REPAIR INSTRUCTIONS

REASSEMBLY
Refer back to Figure 216.
1. Install the one-piece pump gear/shaft (6)
and thrust washer (15) in the housing and
check for free spin.
2. Install key (5) in the pump gear shaft (6).
3. Place gear (3) on the shaft, aligning the slot
with the shaft key. Press the driven gear on
the shaft.
4. Install washer (2) and self-locking nut (1) on
the shaft. Tighten the nut to specification,
60 lb-ft (81 N•m), using torque wrench
J 24407, or equivalent.
5. Install the idler gear (14) on the housing
shaft.
6. Install cover (7) on the pump and secure the
cover with capscrews. Tighten the
capscrews to specification, 15 lb-ft (20 N•m).
Apply Loctite
®
271 to all capscrews used to
assemble the oil pump.
7. Install the oil pressure relief valve plunger
(11) in the relief valve housing (4).
To maintain correct oil pressure for the various oil
system arrangements, the proper oil pressure
relief valve spring and cap combination must be
used. Using incorrect components may result in
either high or low oil pressure, and contribute to
premature engine damage.
8. Install the oil pressure relief valve spring (12)
in the relief valve housing.
9. Clean the relief valve cap (13) and install it in
the relief valve housing.
10. Install the pump inlet flange plate (9) and
gasket (8) on the housing. Secure the plate
with capscrews (10).
11. Install the oil inlet (pickup) tube and screen
assembly.
Because the inlet tube must be in a vertical
position when installed in the engine, the
mounting flange bolt pattern is off-set to the same
degree as the oil pump-to-cylinder block
mounting angle. The mounting flange of the inlet
tube has four bolt holes marked with an F or R to
distinguish which two holes are used for the front
sump, and which two holes are used for rear
sump applications. Caution must be used to
ensure that the correct mounting holes are used
for the proper sump applications.

PROCEDURES
Oil Cooler Reconditioning
[215 DW]
Early-production engines with the right-side
mounted EECU are equipped with a removable
bundle-type oil cooler that can be disassembled,
inspected and tested, and the bundle replaced if
necessary. The plate-type oil cooler (Figure 220)
on current-production engines with the left-side
mounted EECU cannot be disassembled. Should
it fail, it is replaced as an assembly.

The following disassembly and assembly
procedures apply only for the removable bundle-
type oil cooler.
