CLEANING
1. Wash all parts in a suitable solvent.
INSPECTION
CAUTION: Oil pump pressure relief valve and
spring should not be removed from the oil pump.
If these components are disassembled and or
removed from the pump the entire oil pump
assembly must be replaced.
1. Clean all parts thoroughly. Mating surface of the oil
pump housing should be smooth. If the pump cover
is scratched or grooved the oil pump assembly
should be replaced.
2. Lay a straight edge across the pump cover surface
(3). If a 0.025 mm (0.001 in.) feeler gauge (2) can
be inserted between the cover and the straight
edge the oil pump assembly should be replaced.
3. Measure the thickness of the outer rotor. If the
outer rotor thickness measures at 12.005 mm
(0.472 in.) or less the oil pump assembly must be
replaced.

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re-timing the complete timing drive.Once the timing drive is rotated bluelink-to-dot alignment is no longer
valid.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