CLUTCH 7 - 3

1. Remove plug (A), Figure 4, using socket wrench J-472.
FIGURE 4
2. Crank engine slowly until the star on flywheel is aligned
with the timing pointer at the timing inspection hole.
This will bring the drain hole to the bottom of flywheel
and allow complete drainage.
3. Crank engine until the drain hole again appears at the
timing inspection hole and insert 1/3 of a pintof Hud-
sonite Clutch Compound using J-485 Clutch Filler Gun.
4. Install plug (A).
The measuring cup J-486 is calibrated and should be used for
measuring the clutch compound unless the "one shot" 1/3 pint can
is used.
CLUTCH FLUSHING
Following is the method recommended for draining and cleaning
the clutches of Hudson cars in order to remove gum and oxidation
deposits which cause clutch sticking.
It is important that this procedure be closely followed and the
engine run sufficiently to warm up the clutch parts to approxi-
mately 100° before flushing. If the parts are at a low temperature the
solvent will not be effective and on the other hand, if the tempera-
ture is too high, much of it will vaporize
PROCEDURE:
1. Remove flywheel dust pan and turn fly-wheel until drain
plug is at its lowest position. Remove plug and drain out
the old clutch compound.
2. Turn flywheel until clutch filler hole is opposite timing
opening in rear engine plate and with a filler gun, inject
one pintof solvent. (20% carbon tetrachloride and 80%
commercial acetone. Obtainable from drug or chemical
supply houses.)
3. Replace plug and with a stick of the proper length o r a
clutch pedal depressor, hold clutch in disengaged posi-
tion. With engine at rest, permit clutch to remain disen-
gaged for about 10 minutes. Release pedal and turn
flywheel and clutch by hand approximately 1/4 turn,
remaining in this position another 10 minutes.
Repeat this operation depressing clutch pedal and turn-
ing flywheel 1/4 turn each time until a complete revolution
is made. This will give the solvent an opportunity to act on
all the internal clutch parts.
4. Drain clutch again making sure filler opening is at ex-
treme bottom position to remove all solvent. Turn fly-
wheel until filler opening is again exposed at the rear
engine support plate. Introduce 1/3 pintof new Hud-
sonite compound and replace drain plug.
5. Replace flywheel dust pan.
CLUTCH REMOVAL FROM CAR
(Single Lever Type)
1. Remove front seat cushion.
2. Remove the four bolts attaching the bottom of front seat
frame to seat track, remove two screws attaching seat
adjusting lever to seat frame, and remove seat back and
base from car.
