damage camshaft bearings. Reverse removal procedure to complete
installation. Tighten bolts to specification.
Camshaft Bearing
Replace camshaft bearings using camshaft bearing
remover/installer. Ensure oil holes are aligned after installation.
OIL PAN
See OIL PAN REMOVAL at end of ENGINE section.
PISTON & ROD
NOTE: Mark piston cylinder location for reassembly reference.
Install pistons in original cylinder location.
Removal
1) Remove cylinder head. See CYLINDER HEAD in this article.
Remove oil pan. See OIL PAN REMOVAL at end of ENGINE section. Remove
ridge or deposits from cylinder bore.
2) Mark connecting rod and piston for cylinder
identification. Remove bearing cap. Remove piston and rod assembly.
CAUTION: Arrows on top of piston must point toward front of engine.
Oil squirt holes in connecting rod must face camshaft side
of engine.

* The lock inhibitor assembly consists of a lever that engages
lock levers (preventing locking of steering shaft), a button
to operate lever and a return spring. Assembly is attached to
lock housing in same location as shift gate is on column
shift. Lower steering shaft bearing is mounted in an aluminum
support.
* A spring is attached between shift housing and column jacket.
This spring keeps housing rotated counterclockwise against
rubber bumper.
OVERHAUL
STANDARD COLUMN
NOTE: All columns are similar except for appearance of covers.
Some models use ignition key light, while others do not.
Disassembly and reassembly procedures cover all models. Some
procedures may not apply to every steering column.
Disassembly
1) Pry out wiring trough retainers. Lift off trough. New
retainers may be required for reassembly. Use masking tape to protect
paint and a deep socket to back-up housing. Drive retaining roll pin
out with a punch to remove shift lever.
2) Remove breakaway capsules. Secure column in vise by
clamping at column bracket. DO NOT distort column. Remove turn signal
lever cover-to-lock housing attaching screws. Remove cover. Remove
wiper/washer switch assembly. Pull switch cover up wiper/washer lever.
Remove lever sleeve-to-switch attaching screws.
3) Rotate wiper/washer shaft to full clockwise position.
Remove shaft from switch. Remove turn signal switch and upper bearing
retaining screws. Remove retainer. Lift switch upward out of way.
Unclip horn ground wire. Remove ignition key light retaining screw.
Lift ignition key light out of way.
4) Remove bearing housing-to-lock attaching screws. Remove
snap ring from upper end of steering shaft. Remove bearing housing
from shaft. Remove lock plate spring and lock plate from shaft. Remove
shaft through lower end of column.
5) Remove ignition key. Remove warning switch retaining
screw. Lift out key warning switch. Remove 2 ignition switch-to-column
jacket retaining screws. See Fig. 2. Remove ignition switch by
rotating switch 90 degrees on actuator rod. Remove 2 dimmer switch
retaining screws. Disengage dimmer switch from rod.
