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 output yoke nut (coated with red
Loctite #271) on the output shaft and tighten to 74
ft-lb. Peen the nut to the shaft.
4. Using an appropriate holding fixture and wrench
adapter, install the secondary drive gear nut (threads
coated with red Loctite #271) and tighten to 74 ft-lb.
The output drive assembly is now ready for installa-
tion.
