4. Install a new seal (F), output yoke (G), and nut (H)
and tighten to 74 ft-lb.
NOTE: Do not use a new lock nut at this time as
this procedure may have to be repeated.
5. Place the assembled shaft into the left crankshaft
case; then lightly coat the gear teeth with machinist's
lay-out dye. Rotate the shafts through several rota-
tions in both directions. Gear contact should extend
from the root to the top of the gear teeth.

7. After correct tooth contact is established, proceed to
Checking Backlash in this sub-section.
Checking Backlash
1. If removed, install the secondary drive/bevel gear
shaft into the crankcase; then tighten the nut to 59 ft-
lb.

2. Install the secondary drive bearing support; then
install the secondary driven output shaft into the
crankcase.
3. Mount the dial indicator so the tip is contacting a
tooth on the secondary drive bevel gear.
4. While rocking the drive bevel gear back and forth,
note the maximum backlash reading on the gauge.

5. Acceptable backlash range is 0.115-0.390 mm
(0.005-0.015 in.).
NOTE: If backlash measurement is within the
acceptable range, no correction is necessary.
 NOTE: After backlash and tooth contact are within
specifications, apply red Loctite #271 to the drive-
shaft threads and driven output shaft threads; then
using new nuts, tighten the output shaft nut to 59 ft-lb
and the output yoke nut to 74 ft-lb.
