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re-timing the complete timing drive.Once the timing drive is rotated bluelink-to-dot alignment is no longer
valid.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).

COVER - TIMING
REMOVAL
1. Disconnect the battery negative cable.
2. Drain cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).
3. Disconnect both heater hoses at timing cover.
4. Disconnect lower radiator hose at engine.
5. Remove crankshaft damper (Refer to 9 - ENGINE/
ENGINE BLOCK/VIBRATION DAMPER -
REMOVAL).
6. Remove accessory drive belt tensioner assembly
(1).
7. Remove the generator and A/C compressor.
CAUTION:The4.7LengineusesanRTVsealer
instead of a gasket to seal the front cover to the
engine block, from the factory. For service, Mopar
Grey Engine RTV sealant must be substituted.
NOTE: It is not necessary to remove the water
pump for timing cover removal.
8. Remove the bolts holding the timing cover to
engine block.
9. Remove cover.

INSTALLATION
CAUTION: Do not use oil based liquids to clean
timing cover or block surfaces. Use only rubbing
alcohol, along with plastic or wooden scrapers.
Use no wire brushes or abrasive wheels or metal
scrapers, or damage to surfaces could result.
1. Clean timing chain cover and block surface using
rubbing alcohol.
CAUTION: The 4.7L can use a special RTV sealer
instead of a carrier gasket to seal the timing cover
to the engine block, from the factory. For service
repairs, Mopar
Grey Engine RTV must be used as
a substitute, if RTV is present. If the front cover
being used has no provisions for the water pas-
sage o-rings, then Mopar
Grey Engine RTV must
be applied around the water passages.
2. Inspect the water passage o-rings, if equipped for
any damage, and replace as necessary.
3. Apply Mopar
Grey Engine RTV sealer to the front
cover following the path above, using a 3 to 4mm
thick bead.
