Checking Backlash
1. Install the drive bevel gear assembly and driven bevel
gear/output shaft assembly into the crankcase bottom
cover.
2. Mount the dial indicator so the tip is contacting a tooth
on the secondary drive bevel gear.
3. Firmly hold the bearing down and while rocking the
drive bevel gear back and forth, note the maximum
backlash reading on the gauge.
4. Acceptable backlash range is 0.127-0.381 mm
(0.005-0.015 in.).
Correcting Backlash

NOTE: If backlash measurement is within the
acceptable range, no correction is necessary.
1. If backlash measurement is less than specified,
remove an existing shim, measure it, and install a new
thinner shim.

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 estab-
lished, install a new lock nut (coated with red Loctite
#271) on the output yoke and tighten to 200 ft-lb.
Peen the lock nut to the shaft.

2. Inspect the crankcase for scoring, discoloration, or
cracks in the gerotor bore. If scored, crankcase assem-
bly must be replaced.
