install the appropriate bearing cups into the
housing and cover. Do not install the seal into the
cover yet. Install the input shaft, 1, and cover, 2,
onto the gearbox, and shim (shim pack thickness
of 0.025″ is a good starting point) between the
housing to obtain the appropriate rolling torque

the cover and install the shaft seal by driving it
into the bore until it seats against the shoulder in
the cover. Grease the seal lip liberally before re-
installing the cover. Apply silicone sealant to the
cover sealing flange, 3; reinstall the cover and
