1. Drain and remove the oil pan.
CAUTION - The EPA warns that prolonged contact with used engine oil may
cause a number of skin disorders, incl uding cancer! You should make every
effort to minimize your exposure to used engine oil. Pr otective gloves should be
worn when changing the oil. Wash y our hands and any other exposed skin
areas as soon as possible after exposure to used engine oil. Soap and water, or
waterless hand cleaner should be used.
2. Remove the oil pump-to-rear main bearing cap bolt. Remove the pump
and the extension shaft.
3. Remove the cotter pin, spring and pressure regulator valve.

1. Remove the timing gear cover.
2. With the timing gear cover remov ed, rotate the engine as follows:
a. Place the #1 piston at T.D. C with the marks on the camshaft
sprocket at 6 O'clock and the cranks haft sprocket at 12 0:clock.
b. Make sure the #1 cylinder is on the compression stroke with both
valves closed.
3. Remove the bolts holding the cams haft sprocket to the camshaft. Pull the
camshaft sprocket forward.
4. If the camshaft sprocket will not move, give the sprocket a light blow with
a plastic mallet, on the lower edge. Remove the sprocket and timing
chain.

does not fall into the oil pan.
To install: 6. Install the crankshaft gear about
1/2 inch from the crankshaft stop.
7. Position the chain onto the cam gear, then slide the chain and cam gear
onto the crank gear and camshaft, keepi ng the timing marks aligned at
all times.
8. Install the camshaft gear retaining bolts and tighten.

gear and realign.
2.5L ENGINE

Fig. 4: Timing gear alignment - 2.5L
The 4-cylinder engine uses a gear driven camshaft. To remove the timing gear,
refer to the camshaft removal section. The camshaft must be removed from the
engine so that the timing gear ma y be pressed from the shaft.
WARNING - The thrust plate must be posit ioned so that the woodruff key in the
shaft does not damage it when the shaft is pressed out of the gear. Properly
support the hub of the gear or the gear will be seriously damaged. The
crankshaft gear may be removed with a gear puller while in place in the block.
CRANKSHAFT SPROCKET
REMOVAL & INSTALLATION 1. Remove the front cover and timing chain.
2. To remove the crankshaft sprocket, it may be necessary to remove the
radiator to gain su fficient clearance.
3. Using a puller, remove the crankshaft sprocket.
4. To install, pay attention to the position of the woodruff key. Slide the
sprocket onto the crankshaft.
5. To complete the installation, reverse the removal procedures.

2. Remove the fan, driv
e belts and water pump pul ley. Remove the valve
cover. Loosen the rocker arms and pivot them, then remove the
pushrods.
3. Remove the oil pump driveshaft and gear assembly. This is located
under a small plate secured by two bol ts near the oil filter. Remove the
spark plugs.
4. Mark the position of the distribut or rotor, housing, and engine block.
Remove the distributor.
5. Remove the valve lifters. They are located behind the pushrod cover.
6. Remove the timing gear cover.
7. Insert a screwdriver through the holes in the ti ming gear and remove the
2 camshaft thrust plate screws.
8. Pull the camshaft and gear assembly out through the front of the engine
block.
When removing the camshaft, be careful not to damage the camshaft bearings.
9. If the camshaft is to be removed from the timing gear, place the assembly in an arbor press and s eparate. CAUTION When removing the
timing gear from the camshaft, the thrust plate must be positioned so that
the woodruff key does not damage it.
To install: 10. To install the timing gear to the camshaft, press the assembly together
and measure the end clearance. T here should be 0.0015-0.0050 in.
(0.038-0.127mm) between the thrust plate and the camshaft.
If the clearance is less than 0.0015 in. (0 .038mm), replace the spacer ring; if
more than 0.0050 in. (0.127mm), replace the thrust ring.
11. Lubricate the camshaft, bearings, and lifters. Slide the camshaft
assembly into the engine and align the timing marks of the camshaft gear
and crankshaft gear.
12. Complete the installation by reversing the removal procedure.

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.
