6. Apply grease to the sealing lip on the shaft seal,
and press them into place on each side of the
housing.
NOTICE: The seal must be pressed into place with
a seal installing tool or suitable substitute. The seals
must be flush with the side of the housing, and square
to the shaft. If the seal is driven in with a hammer, it
will be distorted and leak, causing disc module
failure.
7. Apply silicone sealant to the threads of the drain
plug and check plug, and install them into the
housing. Pour 300 ml of Case Akcela 135 H EP
80W90 gear oil through the top opening into the
lower module.
8. Apply a thin bead of silicone sealant to the sealing
flange of the new top cap assembly, and position it
on the lower module assembly with the breather
facing to the right. Apply silicone sealant to the
end of the threads of the top cap retaining bolts,
install them and torque to 113 N⋅m (83 lb ft).
Do not install the disc hub onto the top cap at this
time, unless it is desired to check backlash. To
check backlash, the disc hub must be installed
and torqued to 224 N⋅m (150 lb ft) to seat bevel
shaft against bearings and housing.
Acceptable backlash is 0.005 inch to 0.011 inch. If
backlash is unacceptable, recheck assembly of
the disc module.
