D. Rotate the pliers and monitor the dial indicator
reading to check gearbox backlash. Allowable back-
lash is from 0.006” to 0.013” (0.16 to 0.33 mm).
E. If backlash adjustment is necessary, remove gas-
ket(s) from between quill and gearbox housing to de-
crease backlash. Increase backlash by installing
additional gasket(s). Recheck backlash after any
gasket change. Repeat process until backlash is cor-
rect.

After backlash is correct, check gear pattern to as-

E. Ideal pattern should cover from 40% to 80% of the
gear face width (Fig. 43). The contact area should be
in the center of each tooth and extend from 20% to

of the gear face height. The pattern should not
run off the tooth heel, toe or top.
F. If necessary, adjust the number of soft shim(s)
between housing and inner bearing cone to correct
gear pattern. Make sure to also check and adjust
cross shaft end play.
