FILTER - ENGINE OIL
REMOVAL
All engines are equipped with a high quality full-flow,
disposable type oil filter. DaimlerChrysler Corporation
recommends a Mopar
or equivalent oil filter be used.
1. Position a drain pan under the oil filter.
2. Using a suitable oil filter wrench loosen filter.
3. Rotate the oil filter counterclockwise to remove it
from the cylinder block oil filter boss.
4. When filter separates from cylinder block oil filter
boss, tip gasket end upward to minimize oil spill.
Remove filter from vehicle.
NOTE: Make sure filter gasket was removed with
filter.
5. With a wiping cloth, clean the gasket sealing sur-
face of oil and grime.
INSTALLATION
1. Lightly lubricate oil filter gasket (2) with engine oil.
2. Thread filter (3) onto adapter nipple. When gasket
makes contact with sealing surface, hand tighten
filter one full turn, do not over tighten.
3. Add oil, verify crankcase oil level and start engine.
Inspect for oil leaks.

STANDARD PROCEDURE
STANDARD PROCEDURE - MEASURING TIMING CHAIN WEAR
NOTE: This procedure must be performed with the
timing chain cover removed.
1.Removethetimingchaincover.(Referto9-
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - REMOVAL).
2. To determine if the secondary timing chains are
worn, rotate the engine clockwise until maximum
tensioner piston (2) extension is obtained. Measure
the distance between the secondary timing chain
tensioner housing and the step ledge on the piston.
The measurement at point (A) must be less than
15mm (0.5906 inches).
3. If the measurement exceeds the specification the
secondary timing chains are worn and require
replacement. (Refer to 9 - ENGINE/VALVE TIM-
ING/TIMING BELT/CHAIN AND SPROCKETS -
REMOVAL).
NOTE: If the secondary chains are to be replaced
the primary chain must also be replaced.
STANDARD PROCEDURE - ENGINE TIMING - VERIFICATION
CAUTION: The 4.7L is a non free-wheeling design engine. Therefore, correct engine timing is critical.
NOTE: Components referred to as left hand or right hand are as viewed from thedriverspositioninsidethe
vehicle.
NOTE: The blue link plates on the chains and the dots on the camshaft drive sprockets may not line up
during the timing verification procedure. The blue link plates are lined up with the sprocket dots only when
re-timing the complete timing drive.Once the timing drive is rotated bluelink-to-dot alignment is no longer
valid.
Engine base timing can be verified by the following procedure:
1. Remove the cylinder head covers (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDERHEADCOVER(S)-
REMOVAL).

2. Using a mirror, locate the TDC arrow on the front
cover. Rotate the crankshaft until the mark on the
crankshaft damper is aligned with the TDC arrow
on the front cover. The engine is now at TDC.
3. Note the location of the V8 mark stamped into the camshaft drive gears. IftheV8markoneachcamshaftdrive
gear is at the twelve o’clock position, the engine is at TDC (cylinder #1) onthe exhaust stroke. If the V8 mark on
each gear is at the six o’clock position, the engine is at TDC (cylinder #1) on the compression stroke.
4. If both of the camshaft drive gears are off in the same or opposite directions, the primary chain or both second-
ary chains are at fault. Refer to Timing Chain and Sprockets procedure in this section.
5. If only one of the camshaft drive gears is off and the other is correct, theproblem is confined to one secondary
chain. Refer to Single camshaft timing, in this procedure.
6. If both camshaft drive gear V8 marks are at the twelve o’clock or the six o’clock position the engine base timing
is correct. Reinstall the cylinder head covers.
SINGLE CAMSHAFT TIMING
NOTE: to adjust the timing on one camshaft, peform the following procedure.

TIMING CHAIN & SPROCKETS
REMOVAL
1. Disconnect negative cable from battery.
2. Drain cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).
3. Remove right and left cylinder head covers (Refer
to 9 - ENGINE/CYLINDER HEAD/CYLINDER
HEAD COVER(S) - REMOVAL).
4. Remove radiator fan shroud.
5. Rotate engine until timing mark (2) on crankshaft
damper aligns with TDC mark on timing chain
cover (2) (#1 cylinder exhaust stroke) and the cam-
shaft sprocket “V8” marks are at the 12 o’clock
position (1,2).

CAUTION: Care should be taken not to damage
camshaft target wheel. Do not hold target wheel
while loosening or tightening camshaft sprocket.
Do not place the target wheel near a magnetic
source of any kind. A damaged or magnetized tar-
get wheel could cause a vehicle no start condition.
CAUTION: Do not forcefully rotate the camshafts
or crankshaft independently of each other. Damag-
ing intake valve to piston contact will occur.
Ensure negative battery cable is disconnected to
guard against accidental starter engagement.
13. Remove left and right camshaft sprocket bolts.
14. While holding the left camshaft steel tube with
adjustable pliers (1), remove the left camshaft
sprocket. Slowly rotate the camshaft approxi-
mately 15 degrees clockwise to a neutral position.
15. While holding the right camshaft steel tube with
adjustable pliers (1), remove the right camshaft
sprocket. Slowly rotate the camshaft approxi-
mately 45 degrees counterclockwise to a neutral
position.
16. Remove idler sprocket assembly bolt.
17. Slide the idler sprocket assembly and crank
sprocket forward simultaneously to remove the
primary and secondary chains.
18. Remove both pivoting tensioner arms and chain
guides.
19. Remove chain tensioner.

7. Install both secondary chains onto the idler
sprocket. Align two plated links on the secondary
chains to be visible through the two lower openings
on the idler sprocket (4 o’clock and 8 o’clock).
Once the secondary timing chains are installed,
position special tool 8515 (6) to hold chains in
place for installation.
8. Align primary chain double plated links with the tim-
ingmarkat12o’clock(1)ontheidlersprocket.
Align the primary chain single plated link with the
timing mark at 6 o’clock on the crankshaft sprocket
(3).
9. Lubricate idler shaft and bushings with clean
engine oil.
10. Install all chains, crankshaft sprocket, and idler
sprocket as an assembly. After guiding both sec-
ondary chains through the block and cylinder
head openings, affix chains with a elastic strap or
the equivalent, This will maintain tension on
chains to aid in installation.
NOTE: It will be necessary to slightly rotate cam-
shafts for sprocket installation.
11. Align left camshaft sprocket “L” dot to plated link
on chain.
12. Align right camshaft sprocket “R” dot to plated link
on chain.
CAUTION: Remove excess oil from the camshaft
sprocket bolt. Failure to do so can result in over-
torque of bolt resulting in bolt failure.
13. Remove Special Tool 8515, then attach both sprockets to camshafts. Remove excess oil from bolts, then Install
sprocket bolts, but do not tighten at this time.
14. Verify that all plated links are aligned with the marks on all sprocketsand the “V8” marks on camshaft sprockets
are at the 12 o’clock position.
CAUTION: Ensure the plate between the left secondary chain tensioner and block is correctly installed.
15. Install both secondary chain tensioners. Tighten bolts to 28 Nꞏm (250 in. lbs.).
