2. If backlash measurement is more than specified,
remove an existing shim, measure it, and install a
thicker shim.
 NOTE: Continue to remove, measure, and install
until backlash measurement is within tolerance. Note
the following chart.
Backlash Measurement
Under 0.127 mm (0.005 in.)
At 0.127-0.381 mm (0.005-0.015 in.)
Over 0.381 mm (0.015 in.)
3. Once correct gear pattern and backlash are established,
install a new output flange nut (coated with red Loctite
#271) on the output shaft and tighten to 200 ft-lb.
4. Using an appropriate holding fixture and wrench
adapter, install the secondary drive gear nut (threads
coated with red Loctite #271) and tighten to 200 ft-lb.
The output drive assembly is now ready for installa-
tion.
OIL PUMP ASSEMBLY
Disassembling and Inspecting
1. Remove the oil pump cover; then remove the gerotor
set, shaft, and pin (see Disassembling Crankcase Half
in this sub-section).
2. Inspect the crankcase for scoring, discoloration, or
cracks in the gerotor bore. If scored, crankcase assem-
bly must be replaced.
3. Inspect the gerotor set for scoring, discoloration, or
cracks; then using a feeler gauge, check the inner to
outer rotor clearance. If measurements exceed specifi-
cations, the gerotor set must be replaced.
