Refer to Group 14, Fuel System, for the proper pro­
cedures.
(10) If the engine is hot, remove the cylinder head
bolts in the sequence shown in Fig. 7..The removal sequence is not important if the engine is cold. There
are 3 sizes of head bolts. Note the position of each
bolt for future installation.
(11) Remove the cylinder head and gasket from the
cylinder block.

INSPECTION
Remove the cup plugs and inspect the coolant pas­

sages.
A large build up of rust and lime will require
removal of the cylinder block for cleaning in a hot
tank.
Inspect the cylinder bores for damage or excessive
wear. Rotate the crankshaft so the piston is at Bot­
tom Dead Center (BDC) to inspect the bores. Measure the cylinder bores (Fig. 8). DO NOT pro­
ceed with in-chassis repair if the bores are damaged
or worn beyond the limits (refer to Cylinder Bore Re­
pair - Cylinder Block).
Check the top surface for damage caused by the
cylinder head gasket leaking between cylinders.
Inspect the block and head surface for nicks, ero­
sion, etc. Check the head distortion (Fig. 9). The distortion of
the combustion deck face is not to exceed 0.010 mm (0.0004 inch) in any 50.8 mm (2.00 inch) diameter.
Overall variation end to end or side to side 0.30 mm (0.012 inch).
(3) Disconnect the radiator and heater hoses (refer
to Group 7, Cooling System). (4) Remove the turbocharger.
(5) Remove the exhaust manifold (Fig. 4).

OVERHAUL SERVICE
INFORMATION

Inspect all the transmission bushings during over­
haul. Bushing condition is important as worn, scored
bushings contribute to low pressures, clutch slip and accelerated wear of other components. Do not replace
bushings as a matter of course. Replace bushings
only when actually worn or scored. Use recommended tools to replace bushings. The
tools are sized and designed to remove, install and seat bushings correctly, The bushing replacement
tools are included in Bushing Tool Set C-3887-B. The
tool set is manufactured by the Miller Tool Co. and is available through the dealer tool program. Pre-sized service bushings are available for re­
placement purposes. Only the sun gear bushings are
not serviced. Low cost of the sun gear assembly
makes it easier to simply replace the gear and bush­
ings as an assembly. Heli-Coil inserts are recommended for repairing
damaged, stripped or worn threads in aluminum

parts.
These inserts are available from most automo­
tive jobbers. Stainless steel inserts are preferred. The use of crocus cloth is permissible where neces­
sary, providing it is used carefully. When used on
valves, use extreme care to avoid rounding off sharp
edges.
Sharp edges are vital as they prevent foreign
matter from getting between the valve and valve

bore.

Do not reuse oil seals, gaskets, seal rings, or
O-rings during overhaul. Replace these parts as a
matter of course. Also do not reuse snap rings or
E-clips that are bent or distorted. Replace these parts as well.
Lubricate transmission parts with Mopar ATF

Plus,
Type 7176, or Dexron II™ transmission fluid during overhaul and assembly.
Use Ru-Glyde or Door Eze to lubricate clutch pis­
ton seals. Use petroleum jelly to lubricate O-rings and thrust washers. Petroleum jelly can also be used
to hold parts in place during reassembly.

TRANSMISSION
CASE
CLEAN1N8
AND
INSPECTION

Clean the case in a solvent tank. Flush the case
bores and fluid passages thoroughly with solvent. Dry the case and all fluid passages with compressed
air. Be sure all solvent is removed from the case and
that all fluid passages are clear. Do not use shop towels or rags to dry the case
(or any other transmission component) unless
they are made from lint-free materials. Lint will
readily adhere to case surfaces and transmission
components and will circulate throughout the
transmission after assembly. A sufficient quan­
tity of lint can block fluid passages and interfere
with valve body operation. Inspect the case for cracks, porous spots, worn

bores,
or damaged threads. Damaged threads can be repaired with Helicoil thread inserts. However, the
case will have to be replaced if it exhibits any type of
damage or wear.
Lubricate the front band adjusting screw threads
with petroleum jelly and thread the screw part-way into the case. Be sure the screw turns freely.
Remount the case in Repair Stand C-3750-B after
cleaning and inspection.

DISASSEMBLING OVERRUNNING CLUTCH/ LOW-REVERSE DRUM
If the clutch assembly came out with the low-re­
verse drum, thread two clutch cam bolts into the cam. Then lift the cam out of the drum with the bolts (Fig. 29). Rotate the cam back and forth to ease re­
moval if necessary. Remove the clutch roller and spring assembly from the race afterward.
Fig, 29 Removing Overrunning Clutch From Low- Reverse Drum—32RH
CLEANING AND INSPECTION Clean the overrunning clutch assembly, clutch
cam, low-reverse drum and rear support in solvent.
Dry them with compressed air after cleaning. Inspect condition of each clutch part after cleaning.
Replace the overrunning clutch roller and spring as­ sembly if any rollers or springs are worn or dam­
aged, or if the roller cage is distorted, or damaged.
Replace the cam if worn, cracked or damaged.
Replace the low-reverse drum if the clutch race,
roller surface or inside diameter is scored, worn or damaged. Do not remove the clutch race from the
low-reverse drum under any circumstances. Re­ place the drum and race as an assembly if either component is damaged.
Examine the rear support carefully for wear,
cracks, scoring or other damage. Be sure the support
hub is a snug fit in the case and drum. Replace the support if worn or damaged.
