MAINTENANCE
STEP V
Insert Input Shaft with all components down into Main Housing till Inner Bearing Cone is seated into Inner
Bearing Cup. Rotate output shaft back & forth slightly to determine approx. gear back lash. If backlash seems
large, it will be necessary to remove a shim (item # 7 or 8). If not enough backlash is present then add a shim
(item 7 or 8). Proper gear backlash is between.015" to.025".
STEP VI
Input Seal (item # 6) can be installed now or wait till later. With Shims (item # 9&10) lower Input Bearing Cap
(item # 4) down over Input Shaft. Install Bolts (item # 3) into Bearing Cap and tighten them, Check Bearing Pre-
Load. Bearing Preload should be from 12 to 14 pounds of Rolling Torque, if rolling torque is low remove shim
(item# 9 or 10) and if high, add shims. Check backlash of gears again to make sure they are set correctly.
Reshim using shims (items # 7 & 8) as required Once all shims are properly set remove input cap (item # 4)
and apply gasket sealer and reinstall cap and tighten all bolts to recommended torque levels.
STEP VII
Fill Gearbox with Oil, until proper oil level shows on dipstick, Stop and wait about 10 minutes so oil will have
time to run down around Output Shaft bearings then finish filling with oil, This procedure may take longer on
Cold days or Shorter on Hot days. Always recheck Oil Level after gearbox has been run approximately 1/2
hour.
