The following summary by Milt Webb is
very thorough. It may keep you mighty busy for awhile, but it
should have you ready to tour. If you want a PDF of the original
article including the illustrations, it's here.
GETTING IT READY FOR DURABLE TOURING
Yep, it takes more than a can of gas and a new battery to get a
mothball 'T' [10-50 years storage] ready to go on the road!
You always hear, "It ran OK 10 years ago!" In my experience, it
takes all the checks, cleaning, repairs, and adjustments outlined
below to get through the first mile!
Here's how!
STARTING SYSTEM
Install a new 6-volt battery, negative to ground. Remove and clean
ground strap bolt on the frame. Install a ground strap from the
bolt at the emergency brake cross shaft bracket to the bottom
U-joint cover bolt on the crankcase. Use a heavy woven-style cable
or a #1 gauge cable with flat ends. Loosen one bolt on the starter
and re-tighten. This breaks corrosion, if any.
Remove and disassemble the starter switch. Sand the contacts to
shiny clean. Remove starter cable nut at starter. Tighten bottom
nut to just snug. These are pinned and soldered on the inside.
Sometimes the solder joint breaks loose and the pin pulls out
easily if over-tightened.
Install new #1 gauge cables, from the battery to the switch and
from the switch to the starter. Old cables are usually corroded
even when you cannot see the green.
Caution: Do not use 12 volt cables [number 4 or 6 gauge]. 12-volt
cables will get warm or hot during crank, plus the cranking may be
very slow.
It is best to test the starting system with a digital voltmeter.
For best results, acceptable voltage drop during cranking readings
are:
Cable, batt. to starter switch 0.2 volt max
Starter switch, post-post 0.2 volt max
Cable, starter switch to starter0.2 volt max
Cable, batt. neg.[-] to engine0.2 volt max
Batt. pos. [ +] to neg. [-] 4.5 min [cold]
Battery, positive to negative5.0 min [hot]
Starter draw 400 amps max
See Figure 1 on "How to Make Voltage Drop Measurements".
For better starter switch durability, install a '48 Ford 6-volt
starter solenoid. Use the 'T' starter switch for the solenoid
'control' switch to ground.
If the starter is 'sluggish' at this point, try spraying some
electronic or motor cleaner on the starter commutator during
crank. If the current draw is over 400 amps, have the starter
re-built.
During re-build, install a seal in the end of the starter mount
housing. See Figure 3 for how to. This will prevent massive oil
leaks out of the starter.
Test starter after re-build by hooking the starter post to a
6-volt battery plus (+) terminal with heavy jumper cables. Hold
the starter on the floor. Connect the negative (-) terminal to the
starter at the mounting bolt flange. Run starter motor [no load].
Grasp the starter shaft and hold to slow down the shaft. If you
can slow it down some, but can't stop it, the starter is good. If
you can stop it [shaft], it won't crank engine. During this test,
the amps will go up to 75 at around 4.3 volts.
IGNITION
The commutator [timer], coils, and coil box are usually in need of
cleaning, adjusting, and tightening. Corrosion takes its toll from
sitting.
Clean the timer and roller [or brush] with solvent and sand the
grounding bars to shiny clean. Sand the roller or brush tip. Sand
the brush-type commutator bars and clean with solvent.
Check the wiring from the commutator to the coil primary for
shorts and opens by disconnecting both ends. for testing.
Re-install wires to commutator, routing them so they will not
touch metal or kink when advancing or retarding the spark.
On roller-type commutators, oil rotor and commutator bars
liberally with motor oil upon re-assembly. On brush-type
commutators. I recommend leaving the brush and commutator strips
dry.
Disassemble the coil box connectors. Clean all the hardware in
muriatic swimming pool acid [goggles and gloves]. It is best to
solder the contacts to the small carriage bolts . Install new wood
[kit from 'T' suppliers]. Treat the wood with water sealer, but do
not paint the wood, especially with black paint. Painting may
cause shorts. Black paint has charcoal, a conductor!
I strongly recommend you let a professional restore the coils,
installing new points and modern condensers, and adjusting to the
correct current draw. You will more than likely have reasonable
trouble-free operation. Adjusting the gap to a 'strong buzz' does
not guarantee good spark.
Clean or replace the spark plugs and adjust the gap to 0.025
inches.
You may want to compare the cost of a distributor to 'T' coil
repair. If you're showing your 'T', stay with the original coils
and timer to maintain authenticity. If you want a driver
[durability and smoother acceleration] purchase a distributor,
6-volt coil, and plug wires.
[I'll interrupt Milt here with a contrary opinion. There is
a popular superstition that a distributor is "more reliable"
than a timer and coils. My experience has been the opposite. I
have been stuck by the side of the road several times by
distributor trouble in other vehicles. I can recall only once
when I had similar trouble with the original Model T ignition
system (a bad timer brush). I have not been on a lot of tours,
but I have been told by some who have that the car which
experiences ignition trouble/breakdown is most often the one
converted to a disturbutor, as the late
Ralph Ricks called it. I believe the "more reliable"
legend is bogus. ~ SJ]
If using a distributor, disconnect the 'T' coil box primary wire
and connect it to the new 6-volt coil + terminal. Connect the coil
°© terminal to the distributor. Use number 14-gauge wire for all
primary wire hook up.
If your 'T' is a 12-volt system, install a 'dropping' resistor to
cut the voltage from 12 to nine.
Adjust the point gap to 0.017 inches if no specification is
provided.
The distributor turns clockwise. Remove number one plug and turn
crank to TDC on the compression stroke. Retard the spark lever,
turn the distributor body in the counter-clockwise direction until
the points just start to open. This is the retarded firing
position on number one cylinder [TDC].
Install the advance linkage and adjust the rod length with the
spark control lever in the retard position to match the retard
position of the distributor. Tighten distributor housing clamp
bolt.
Check advance linkage for binding.
If your new distributor has advance weights, retard to start, then
advance the spark by moving the lever down 1⁄2 inch from the
retard position. The automatic advance will take care of
additional distributor advance at higher RPM.
ENGINE CHECKS
Remove all four plugs and measure the compression. Continually
crank the engine until the compression pressure has built up four
times. Record the compression pressure of each cylinder. A good
'T' engine [cold] will crank 50 psi on each cylinder. 45 psi is
OK. 25 psi is a worn engine or bad valves and there may not be
enough power to propel the car. If the compression pressure varies
over 5 psi from cylinder to cylinder, grind the valves and set the
tappet clearance to around 0.012 inches.
If there's no starter, remove all four plugs. Crank each cylinder
through compression with your thumb covering the plug hole. If the
pressure is about equal in all cylinders, the valves are probably
OK. Also, visually look down each plug hole at top of valves. If
they are the same color, the odds are they're good enough to start
the engine.
Drain the oil. Install four quarts of 20-50 weight oil. Check for
dripping out of the top oil level petcock.
If the old oil is 'jelly' or 'syrup' let it drain overnight.
Install pan plug using a small amount of RTV gasket maker on
washer.
If equipped with an external oiler, disassemble and verify it's
not plugged up.
After start up, let engine warm up for one minute at around 1000
RPM.
Increase the RPM to 1500 and hold it steady. Then, short each
cylinder, one at a time, to detect rod bearing knock. If the rod
knock(s) goes away with a warm engine, the rods are slightly
loose. If the rod knock(s) continues with a warm engine, adjust
the rods to 0.002 inches clearance and install Chevrolet-style oil
dippers ["T" supply houses stock the dippers].
Refer to the 'Engine Manual' published by MTFCA for detailed
procedures.
Drain water and re-fill. Add a cup of StaLube 'soluble oil'.
If the tubes are rusted on the top end, remove radiator and have
it professionally checked and flushed at a radiator shop.
FUEL SYSTEM
In the fuel system, checks include the fuel tank, fuel lines,
filter, carburetor, and intake manifold leaks.
Start at the fuel tank. If it's full of flakey rust inside, or
there is 'algae' and\or it has rust holes in the bottom, have it
restored professionally or replace it.
Disassemble the fuel sediment bowl, clean in muriatic acid and
replace the filter screen.
Set up sediment bowl in vice. Loosen front fitting. Use a propane
torch to heat bowl casting.
Reassemble and install the sediment bowl into the tank. Use
aviation, gas-resistant sealant on the threads. Do not get sealant
inside gas passages. Do not use 'Teflon' tape. Gasoline will
dissolve the tape, and it may get inside, causing flooding
problems.
Pour in one gallon of gas and test for leaks and flow out the
sediment bowl. Install the gas line over the frame rail. Route the
fuel line under the splash shield parallel to the frame rail.
Route fuel line between firewall and frame rail adjacent to
firewall to frame bracket. This routing will minimize heat
transfer into fuel line. Other routings may cause fuel foaming
['vapor lock'].
Disassemble carburetor and clean in carburetor cleaner. If float
needle valve seat is 'frozen' in the carburetor top, leave it
alone. Use old needle valve.
If the needle valve seat can be removed, replace it with a new
'Viton' tip needle and seat or a double check ball-style valve
[Grose Jet].
Test the float [brass] in hot water. If small bubbles escape while
immersed, the float is defective. Replace it!
The older carburetors use a cork float. If intact, sand lightly
with 320 grit sand paper. Coat with gas-resistant epoxy [Hobby
Poxy #1]. Wipe off excess before the epoxy cures. Coat a second
time. Wipe again. Check weight before and after each coating. Less
than 0.1 ounce increase in weight is OK. If more, start again with
a new cork float [available from 'T' parts suppliers].
A new cork float must be coated with very light coats of
gas-resistant epoxy. The same technique discussed above applies to
new cork floats.
Gas-resistant- Try it out; soak a small amount of cured epoxy in
gas. It if softens, try another brand. If the float gets too
heavy, it will sink, causing flooding!
Adjust the float to specification. Turn carburetor upside-down.
Usually, if the float is 'level' with the top surface of
carburetor, the float level is OK.
Re-assemble and install carburetor. Adjust needle valve to one
turn open from seat. Most 'Ts' run at around 1⁄2 to 3⁄4 turn.
If adjustment is a lot different than this on NH carburetors,
something may be wrong with the carburetor or float. Review the
Ford 'T' Service Manual or the Carburetor Manual published by the
MTFCA.
TRANSMISSION
By now, you know if 'neutral' has a slight drag which is normal.
In some cases, long storage and some oils will allow the clutch
disks to 'seize up', caused by 'congealing' of the old oil. If
this occurs, jack up one rear wheel so a 'neutral' will be
available for easy start up.
To test for neutral [before start up] pull the emergency brake
lever all the way back [neutral and rear wheel brake]. If it
cranks with the starter, neutral is OK. If not, pull the engine
through with the hand crank. If no neutral, then try and free up
after start up [see 'Run Start up' later in this text].
If neutral is OK, check the pedal adjustments next. Low gear pedal
should tighten the band just before hitting the floor board. The
high gear lever should begin to engage the clutch shaft lever for
neutral about midway between all the way down and the vertical
position. The rear wheel brakes should not drag at this point.
Pull the brake lever to vertical position; both rear wheels should
have an equal heavy drag [see Rear Axle Drive Shaft and Brake
Adjustment].
The transmission brake pedal should engage about one inch above
the floor board.
The reverse band should engage about halfway between full up and
the floor board.
If band adjustment cannot be obtained, review the Ford 'T' Service
Manual or the Transmission Manual [MTFCA] for relining and
adjustment procedures.
STEERING AND FRONT AXLE
Start with the steering gear. Remove the steering wheel and
steering gear cover. Pack with moly chassis lube or wheel bearing
grease. Lube steering collar [lower part] with grease cup.
Check the pitman arm on the shaft. Many times this nut and arm are
loose on the steering shaft. Check woodruff key for slop. Oil
threads and tighten to around 75 pound feet torque and re-install
the cotter pin.
Test the drag link ball caps for looseness by turning the steering
wheel free play [wheels on ground]. Put your finger between the
cap and the steering arm. If there is 'slop' [more than 1\32
inch], remove cap and grind flat face. Re-install cap and re-check
for clearance [less than 1\32 inch]. If OK, disassemble, grease
with moly lube, tighten bolts and jamb nuts, insert cotter pins.
Test for binding (lock to lock) with wheels off the ground.
If drag link binds, loosen bolts slightly, tighten jamb nuts, and
insert new cotter pins. Check for binding again. Repeat drag link
cap check on the right end steering link.
Check and oil the tie rod ends. If more than 1\32 inch clearance,
replace pins and bushings [See Ford 'T' Service Manual for
procedures]. Rebuild kits are available from the 'T' parts supply
houses.
Check the radius rod 'wishbone' ball and cap. If less than 1\64
inch play side-to-side when turning the steering wheel [front
wheels on ground], grease wishbone ball cap, tighten and \or
replace studs, spring, and nuts. The wishbone ball must be tight
in the socket with no side-to-side play.
Safety wire both studs to each other. Do not use cotter pins. Ball
joint studs may work loose and unscrew.
Remove and inspect the front wheel bearings and grease seals.
Clean bearings in solvent ['paint thinner', not lacquer thinner].
Blow dry with air and then wash in solvent, again. If rollers are
pitted, replace bearings and cups [races].
Grease bearings using moly wheel bearing grease. Install inner
wheel bearing and seal. Install wheel on spindle shaft and screw
on outer wheel bearing. The right spindle axle nut and bearing
should be a left-hand [counterclockwise] thread. The left side is
a right-hand thread. Tighten until snug and back off until light
bearing play exists. Install washer and jamb nut. Tighten jamb nut
to line up cotter pin slots. Bearing play should be just snug with
out binding. Turn wheel [off ground]. If it stops abruptly, loosen
jamb nut, loosen bearing nut _ turn, re-tighten jamb nut. If the
wheel turns freely, adjustment is OK.
Lastly, test the spindle and bushings [king pins] for end [up and
down] play and for vertical plane play.
In the vertical plane check [wheels off ground], grab the top and
bottom of the tire and wiggle in and out. If the outer rim moves
in and out more than one inch, look at spindle bushings and wood
spokes [spoke looseness checks in 'wheels' section]. If in and out
movement at spindle [king pin] bushing is more than 1\64 inch
[0.015"] the spindle pin bushings are very loose and should be
replaced.
Next, test the bushing end play [up and down movement in the
vertical plane]. The end play clearance should be zero. Test by
placing a tire iron under the tire [wheels off the ground]. If end
play clearance is greater than 0 [like 0.005" or 0.010", 0.015" is
1\64 inch], remove cotter pin, loosen jamb nut, tighten spindle
bolt 1⁄4 turn, re-tighten jamb nut, and re-test for end play.
The bottom portion of the axle has a thread for the spindle bolt.
If it's stripped, tighten jamb nut to take up end play. The Ford
'T' Service Manual specifies tightening the spindle bolt until
'resistance' to turning exists.
To avoid wheel wobble at low speed, tighten spindle bolt to just
zero end play, as outlined above. If left tight [resistance]
steering will be hard and the car will steer you and you will be
constantly correcting as you travel down the road.
Oil the oil caps at top of spindle bolt with motor oil. If oil
drips to ground out of bottom bushing, oil holes are open. If not,
disassemble spindle bushing bolt, clean oil holes and re-assemble.
Test for end play, align spindle jamb nut, and install cotter pin.
Test for camber, caster, and toe-in ['gather']. Make a 'plumb bob'
with a string and a nut tied to one end. Measure camber by holding
the string at the top outer surface of tire. Move forward until
string clears the hub cap. The horizontal measurement to tire
surface at bottom is three inches [specified in Ford 'T' Service
Manual].
Test the caster [pitch] by holding a carpenter square
perpendicular to the floor and touching the front surface of
bottom spindle\axle area. Measure the distance from the square to
upper edge of spindle\axle area. This measurement should be the
specified 1⁄4 inch on both spindles.
Measure the 'gather' [toe-in] by holding a tape measure the inside
front rim edge about halfway up from the ground. Measure distance
to same spot on other rim. Move the tape measure to the inside
rear rim edge. The 'toe-in' should be around 3\16 - 1⁄4 inch. For
example, if the front measures 53 1⁄2 inches and the back is 53
3⁄4 inches, the toe-in is 1⁄4 inch.
Many times, the toe-in measurement will be 1⁄2 inch toe-in or up
to 1⁄2 inch toe-out! Needles to say, the car will wander all over
if the above measurements are incorrect.
Review the Ford 'T' Service Manual for detailed procedures to
measure camber, caster, and toe [gather]. Toe is adjustable.
WHEELS
In 1998, the wheels with metal outer rims may be up to 78 years
old! Wood felloe and wood outer rim wheels may be 88 years old!
That's old! If the spokes are loose in any way, consider having
them re-spoked by a professional wheelwright advertised in the
hobby magazines.
The wheel(s) may be slightly out of true in the vertical plane. A
_ inch out of true wobble is OK; but if greater, consider
re-spoking the wheel.
You have read about wheels folding up on curves and causing
accidents. It's worth the price to your family, friends, and
relates, in-laws and outlaws to make safety a top issue!
Do not try shimming, epoxy, or resin to 'tighten' up the spokes.
The heat from the rear brakes may melt the glue to honey, run out
all over the brake, and then collapse!
'NUFF' SAID!
REAR AXLE, DRIVE SHAFT AND BRAKE CHECKS
Test the drive shaft front bushing by removing the drive shaft
housing plugs. Insert a small screwdriver and push up. If it
pushes up 1\64 inch [0.015 inches] the clearance is barely
acceptable the clearance spec for this bushing is 0.002 - 0.006
inches. If the clearance is over 1\64 inches, it's very loose!
This measurement excess may indicate other rear axle wear and
excess end play.
With a screwdriver, move the pin fore and aft to check drive shaft
end play. If over 1\64 inches [0.015"], it's too loose. Although
loose, one can drive the car. Consider re-building the drive shaft
assembly. Check the Ford 'T' Service Manual for overhaul
procedures.
If the drive shaft\U-joint pin is loose, support the bottom of pin
with a _ punch and blocks [hardwood on cement] to the floor. Peen
the top of pin with a 1⁄4 inch punch and a two-pound hammer. Turn
drive shaft 180, and peen the other end. The pin is quite soft.
Grease the drive shaft bushing cup with moly grease, and turn it
in 1⁄2 turn for every trip. The front drive shaft bushing without
grease is a 'high wear' item on a 'T'!
Test the rear axle up and down play with wheels off the ground.
Any play up and down up to 0.005 inches is OK, Test the wheels
with a tire iron on the bottom side of the tire using the iron as
a lever. Lift it up and down. If it's over 0.005 inches, it's
loose! The wear is usually in the bearing axle sleeve upper
outside edge [Part #2509].
To remove wheel hubs, jack up one side. Install a 'knock-out' on
opposite axle shaft. Tighten knock-out. Srike heavy blows on end
of knock-out with a 'sledge' hammer. If really tight, re-check
knock-out. If, after five hard blows, it is not loose, install a
'wheel puller' to remove hub. Most wheel hubs fall off or come
loose with a couple of firm blows.
Remove the bearing [two small screwdrivers] and feel the ridge
wear in the axle sleeve. Remove the race [with puller from 'T'
supply houses]. Install inner axle seals and new 'heat-treated'
sleeves. ['T' supply houses have these parts].
Measure the rear axle bearing diameter with a micrometer. The
standard diameter size of the roller bearing is 0.500 inches. If
it measures 0.495 or more its OK. If it less than 0.495 inches,
replace the bearing.
I personally prefer a bearing 0.002 to 0.003 inches under 0.500
inches.
The looser, the faster the car will go up to an acceptable limit!
While the bearing is out, check the axle end play. If over 1\32
inch [0.031"], it's excessive. If left this way, the axle may
shift in and out causing the drum to rub the brake lining edges.
It may squeal! Check the Ford 'T' Service Manual for correct set
up when re-building the rear axle assembly.
Install inner grease seals [Part #2511] and the bearing sleeves
[there is a left and right sleeve; grease holes must line up!].
Grease the rear axle bearing with heavy duty wheel bearing grease
or moly grease. Install bearings. Tap bearings in lightly and turn
cage back and forth. With old bearings, they will slip in easily.
With new, reproduction bearings, a moderate tap is OK.
When all the way in, the bearings will rotate easily, because the
axle is usually worn from 0.003 to 0.005 inches on the bearing
surface area. If in doubt about the above, review the Ford 'T'
Service Manual for procedures.
Check the brake shoe lining. The small 9-inch brakes with lining
is inadequate for hill country, but may be OK for flat country [a
personal opinion]. You may want to consider 'rocky mountain'
brakes.
The 11-inch brakes ['26°©'27 'T'] is much better and adequate for
mountain driving. 'Fade' may still be a problem.
Recently [1997], I had my 11-inch brakes relined with a 'molded
Kevlar' lining used in industrial brake applications. The brand
name is Redco Heavy Duty Woven Lining. This Kevlar lining will
withstand higher temperatures before fade than Model T brake
lining. If it fades, the brakes will recover faster upon cooling.
After 100 miles, the brakes seated and stopping power is superb
with minimum fade.
In either case, have the lining professionally drilled and riveted
with brake machinery. Don't skimp and do it 'by hand'! It will
work loose! There goes your safety factor!
Oil brake arm cam lever bushings. Put a thin film of moly grease
on the cam surface [top and bottom]. Install lining. Disconnect
brake rods.
Prepare rear axles. Remove axle burrs and shine taper surfaces
with 80 grit-type sand paper. Peen the outer end of the axle
keyway. Insert the axle key by tapping into the burr. You don't
want this to move when installing the wheel hub. Clean axle
threads with a _ x 13 [National Fine] die. Tap nut to clean
thread.
Oil axle surface, axle thread, and nut for a better torque.
Slip on hub drum. Rotate wheel. If you hear a metal scraping, it
may be the brake lining edge rubbing the drum. Remove hub and
install an axle shim [Part #2505 SH] coated with oil. Recheck for
scraping sound.
The oiled axle shaft surfaces will provide a better seating of the
hub on the axle. Install the nut, and snug lightly [for now].
Re-install brake rods, oil clevis pins, and install cotter pins.
Adjust the brakes for equal drag. Pull the emergency brake handle
to the vertical position. Test for equal drag on both wheels.
Move brake lever to neutral with no brake. Test for free-wheeling
at rear wheels. The trick is to have the wheels free in neutral
with no brake drag, then pull lever to vertical. The wheels should
have a heavy equal drag to almost locked up with brake lever in
vertical position.
Make sure emergency brake lever and locking pawl doesn't slip. If
it does, replace it [pawl].
In my experience, the rear brakes are, quite often, adjusted too
tight. If tight, the brake applies the instant you pull the lever
into neutral.
As new brake lining high spots wear in, re-adjust rear brakes for
equal drag as outlined above.
If all the above adjusts out as discussed above, tighten brake rod
clevis jam nuts and install cotter pins in clevis pins.
Torque the axle nuts to 75 foot pounds, align the cotter pin
slots, and insert the cotter pin.
Fill the differential case to bottom edge of fill plug hole with
140 weight gear oil.
START UP
Now, for the big test! If all the above has been performed with
good repair practice and adjusted to specification, your car
should start in 5-10 seconds and almost be ready to drive on tour!
The order of start up and drive events are as follows:
Adjust mixture, engine off
Crank and start
Adjust mixture and spark advance
Test for rod knocks
Test transmission band adjustment
Drive car, test shifting
Drive car, test brakes
Drive car, test for 'wabble'
Test for overheating
Drive car on tour!
Turn on gas and adjust mixture rod to one turn open from seated
position. Hook up battery.
With gas at half throttle and spark in full-retarded position,
crank engine for five seconds. During crank, choke for up to two
seconds.
On hand crank models, use the same throttle and retarded spark
settings as previously discussed. With ignition off, pull crank
through three times with full choke. Release choke.
Turn on ignition, leave spark retarded, and crank to start.
Upon start up, be prepared to choke slightly as the engine begins
to rev up. If it's 'sputtering', open choke [no choke] to let it
rev up more. Advance spark to half way on 'Ts' equipped with four
coils and timer. To lean the mixture, turn mixture knob clockwise
until the engine 'smooths out'.
Return to idle slowly. Adjust idle throttle screw and mixture rod
to maintain good idle smoothness.
NOTE: In my experience, the mixture rod will be open around 3⁄4
turns from seated position at 1⁄2 throttle. Idle mixture setting
for a long idle usually requires about 1⁄4 turn more rich
[counter-clockwise] than at 1⁄2 throttle in neutral.
During warm up, rev engine to around 1200 RPM. Leave it at a
steady RPM. Listen for knock(s).
Short [with a screwdriver], one spark plug at a time. That
cylinder will drop in RPM. Simultaneously, listen for knock while
plug is shorted. If the knock goes away while shorting out the
cylinder, the rod is loose.
Perform the same test on remaining cylinders.
After a long warm up, perform the same rod knock test, again. If
it still knocks, the rod(s) is\(are) very loose.
In addition, test for center main bearing knock by holding at _
throttle and spark advanced halfway. Short number two and three
spark plug simultaneously. If the knock goes away, adjust the
center main after you adjust the rods. If you have any doubt about
knocks, review the MTFCA Engine Manual for procedures.
To test the transmission bands, set emergency brake and start
engine. Warm up. With emergency brake set, push in low pedal
gently. Listen for a changing transmission 'whine'. This is the
beginning of low band engagement. This point should be around one
°© two inches up from the floorboard surface.
Next, push in reverse pedal with emergency brake set. The pedal
should travel about half-way (1⁄2) to the floorboard surface.
With new, or old transmission bands, start with the above
suggested adjustments. The real test is on the road. The
adjustments may seem on the 'loose' side to you. However, the
loose adjustments will minimize premature failure due to excessive
drag.
If the bands are too tight, they will already be partially
engaged. They may work against each other, and the transmission
may sound like it's binding up. Further the bands may burn and
fail prematurely due to lack of oil [cooling].
Sometimes the clutch disks will not allow a neutral. To test for
neutral while running with one wheel jacked up, pull brake lever
back slowly to neutral. Note RPM change, if any. Then continue to
pull increasing brake drag. Engine RPM should not change and
transmission neutral is OK.
If engine slows down during this maneuver, clutch disks are hung
up and\or oil is congealed on disks' surfaces. Try this brake
on\off procedure for 10 minutes.
If it [neutral] still does not work, change oil again. Repeat
above steps. If it still hangs up, remove, disassemble engine and
transmission to repair clutch.
READY FOR ROAD TEST
Now the big plunge! You're ready for the road!
If you are not experienced, ask an experienced friend who
regularly drives 'Ts' on tours to drive your car the first time.
Slowly, slowly, engage reverse pedal gently and back out of the
driveway. Leave emergency brake in neutral position to hold clutch
pedal in place, while backing up.
Push in low pedal to move forward. Leave emergency brake lever in
neutral. Accelerate to 10 MPH in low, then let up on the throttle
and low pedal.
Let the car coast. Then apply foot brakes, gently. No chatter
during stop- Next accelerate to 10 MPH in low. With your foot
still on low pedal let the brake lever into high gear position
[all the way down]. At 10 MPH, let throttle off slightly and
simultaneously let clutch [high gear] engage by slowly letting up
low pedal.
Note how smooth the shift is! If it chatters, the clutch disks may
be 'hanging up' on the inside of the transmission brake drum
guides.
After 50 miles or so, change the crankcase oil, again. When
bringing your car out of mothballs, the syrupy oil could cause the
hangup and rough shift. New oil may minimize the rough shift.
You have been applying the emergency brake gently, noting pull. At
30 MPH in high gear, let up on throttle and pull emergency brake
to lock the rear wheels [panic stop]. Be prepared for a pull to
right or left.
If it pulls to right, adjust the left clevis pin one turn tighter
and re-install cotter pin. Try panic stop again. If you cannot get
equal pull, re-line emergency brakes as discussed in brake
section.
Test for 'Wabble':
Proceed over chuck holes slowly [5 MPH]. If shimmy develops,
re-check front end looseness and alignment checks, as outlined in
the 'Front Axle' section.
Test the radiator. If it boils on a cool day during these pre-tour
tests, consider a 'flat tube' radiator re-core or a new radiator.
In a good radiator system, water pumps are unnecessary, even on
hot days.
READY FOR TOUR
If all the above works as outlined above, you're now ready for a
durable tour.
Before every tour:
_Fill radiator to 1⁄2 inch from full up
_ Check oil drip out of top petcock
_ Clean timer
_Fill tank with gas
_Turn front drive shaft bushing grease cup one turn.
_Start, warm up, and go on tour!
