REPAIR INSTRUCTIONS, PART 1
REASSEMBLY
Refer back to Figure 306.
1. Install the one-piece pump gear/shaft and
thrust washer in the housing and check for
free spin.
2. Install the key in the pump gear shaft.
3. Place the driven gear on the shaft, aligning
the slot with the shaft key. Then, press the
driven gear onto the shaft.
4. Install the washer and self-locking nut on the
shaft. Tighten the nut to specification,
60 lb-ft (81 N폷m), using torque wrench
J 24407, or equivalent.
5. Install the idler gear on the housing shaft.
6. Apply Loctite
®
271 to the threads of the
cover capscrews and install the cover.
Tighten the capscrews to specification,
15 lb-ft (20 N폷m).
7. Install the oil pressure relief valve plunger in
the relief valve housing.
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 in
the relief valve housing.
9. Clean the relief valve cap and pressure relief
spacers (if equipped with spacers at
disassembly). Install the spacers over the
cap threads (if required for cold pressure
relief) and install the cap in the bore of the oil
pump housing cover. Tighten the pressure
relief cap to specifications.
10. Apply Loctite
®
271 to the threads of the
pump inlet flange plate capscrews. Install
the flange plate and gasket on the housing
and secure the flange plate with the
capscrews.
11. Apply Loctite
®
271 to the threads of the oil
inlet (pickup) tube capscrews. Install the
inlet tube and screen assembly. Secure the
assembly with the capscrews.
Because the inlet tube must be in a vertical
position when installed in the engine, the
mounting flange bolt pattern is offset 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.
