BEARING
REMOVAL & INSTALLATION
It is recommended for a machine shop to perform these procedures.
To remove the camshaft bearings, the ca mshaft lifters, flywheel, rear camshaft
expansion plug, and cranks haft must be removed.
Camshaft bearings can be replaced wi th engine completely or partially
disassembled. To replace bearings without complete disassembly remove the
camshaft and crankshaft leaving cylinder heads attached and pistons in place.
Before removing crankshaft, tape threads of connecting rod bolts to prevent
damage to crankshaft. Fasten connecting rods against sides of engine so they
will not be in the way while replacing camshaft bearings.
If excessive wear is indicated, or if the engine is being completely rebuilt,
camshaft bearings should be replaced as follows: Drive the camshaft rear plug
from the block. Assemble the removal puller with its shoulder on the bearing to
be removed. Gradually tighten the puller nut until bearing is removed. Remove
remaining bearings, leaving the front and rear for last. To remove front and rear
bearings, reverse position of the tool, so as to pull the bearings in toward the
center of the block. Leave the tool in th is position, pilot the new front and rear
bearings on the installer, and pull them into position as follows:
• 4 cylinder engines: Ensure oil holes are properly aligned.
• V6 engines: Ensure the rear and intermediate bearing oil holes are
aligned between the 2 and 3 o'clock po sitions and the front bearing oil
holes are at 1:00 and between 2 and 3 o'clock positions.
• V8 engines: Ensure the No. 1 (f ront) camshaft bearing holes are an
equal distance from the 6 o'clock pos ition. The No. 2 through 4 inner
bearing holes must be posit ioned at the 5 o'clock position towards the left
side (drivers) of the engine, even wit h the bottom of the cylinder bore.
The No. 5 bearing oil holes must be positioned at 12 o'clock.
Return the tool to its original position and pull remaining bearings into position.

Ensure that oil holes are properly al
igned. Replace camshaft rear plug, and
stake it into position to aid retention.
INSPECTION
CAMSHAFT LOBE LIFT
Check the lift of each lobe in consecutiv e order and make a note of the reading.
1. Remove the fresh air inlet tube a nd the air cleaner. Remove the heater
hose and crankcase ventilation hoses. Remove valve rocker arm
cover(s).
2. Remove the rocker arm stud nut or fulcrum bolts, fulcrum seat and rocker
arm.
3. Make sure the pushrod is in the valve tappet socket. Install a dial indicator so that the actuating poin t of the indicator is in the pushrod
socket (or the indicator ball socket adapter tool is on the end of the
pushrod) and in the same plane as the pushrod movement.
4. Disable the ignition and fuel systems.
5. Install a remote starter switch. Crank the engine with the ignition and fuel
system disabled. Turn the crankshaft ov er until the tappet is on the base
circle of the camshaft lobe. At this position, the pushrod will be in its
lowest position.
6. Zero the dial indicator. Continue to rotate the crankshaft slowly until the
pushrod is in the fully raised position.
7. Compare the total lift recorded on the dial indicator with the specification
shown on the Camshaft Specification chart.
To check the accuracy of the original in dicator reading, continue to rotate the
crankshaft until the indicator reads zero. If the lift on any lobe is below specified
wear limits listed, the ca mshaft and the valve tappet operating on the worn
lobe(s) must be replaced.
8. Install the rocker arm, fulcrum seat and stud nut or fulcrum bolts. Adjust
the valves, if required (r efer to the valves procedure in this section).
9. Install the valve rocker arm cover(s) and the air cleaner.
CAMSHAFT END PLAY
On all gasoline V8 engi nes, prying against the aluminum-nylon camshaft
sprocket, with the valve train load on t he camshaft, can break or damage the
sprocket. Therefore, the rocker arm adj usting nuts must be backed off, or the
rocker arm and shaft assembly must be loosened sufficiently to free the
camshaft. After checking the camshaft e nd play, check the valve clearance.
Adjust if required (refer to procedure in this section).
1. Push the camshaft toward the rear of the engine. Install a dial indicator or
equivalent so that the indicator point is on the camshaft sprocket
attaching screw.

1. Remove the intake manifold, valve
cover and pushrod cover (4-cylinder).
Disassemble the rocker arms and remove the pushrods.
2. Remove the lifters. If they are coat ed with varnish, clean with carburetor
cleaning solvent.
3. If installing new lifters or you have disassembled the lifters, they must be
primed before installation. Submer ge the lifters in SAE 10 oil and
carefully push down on the plunger with a
1/8 in. (3mm) drift. Hold the
plunger down (DO NOT pum p), then release the plunger slowly. The lifter
is now primed.
4. Coat the bottoms of the lifters wit h Molykote® before installation. Install
the lifters and pushrods into the e ngine in their original position.
5. Install the rocker arms and adjust the valves. Complete the installation by
reversing the removal procedure.
FREEZE PLUGS
REMOVAL & INSTALLATION
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.
1. Disconnect the negative battery cable.
2. Drain the cooling system.
3. Raise and support the vehicle safely.
4. Remove the coolant drain plug on t he side of the block, if equipped. If not
you can use a punch to put a small ho le in the center of the freeze plug
that is being replaced.
5. Remove all components in order to gain access to the freeze plug(s).
6. Using a punch, tap the bottom corner of the freeze plug to cock it in the
bore. Remove the plug using pliers.
7. Clean the freeze plug hole and c oat the new plug with sealer.
8. Using a suitable tool, install the freeze plug into the block.
9. Connect the negative battery cable, fill the cooling system, start the
engine and check for leaks.
