mined, make final assembly of input caps to gearbox
housing.
B. Install both open caps (item 14) (o–ring and seal
not installed on cap) to gearbox housing. Torque cap
screws 8 ft–lb (10.8 N–m) while checking for binding
of shaft. If shaft binds as screws are tightened, add
additional shims.
A. Remove open input caps from housing.
B. Install new o–ring into groove of input cap. Apply
light coat of grease on o–ring and gearbox housing
bore.
C. After both input caps are installed, check end play
of worm (input) shaft. Shaft end play should be .001”
to .003” (.025 to .076 mm). End play can be adjusted
by adding or removing shims from between input
caps and gearbox housing. Total shim thickness at
one input cap should be within .005” (.13 mm) of the
total shim thickness of the other cap.
C. Taking care not to damage o–ring or shims, install
input cap over input shaft and into housing.
D. Apply Loctite #242 to cap screw threads. Install
and torque cap screws 8 ft–lb (10.8 N–m).
