Differential Case Reassembly: Hydra-Lok ®
The WJ44-4 axle also may be equipped with the
Spicer Hydra-Lok differential assembly. The Hydra-
Lok unit itself is not field serviceable (Figure 76).
However, care must be taken when removing the
differential case and reinstalling it in the carrier to
avoid damaging the plenum.
1. Carefully remove the Hydra-Lok differential
assembly from the carrier (Figure 77).
2. Remove the bearing from the case using Miller
tool adapters 8353 (Figure 78).
Be sure the tab on each adapter
fits in the plenum windows around the bearing
on the flange side.
3. Remove the bearing from the button side of
the case using the same tooling.
NOTE: To order a new Hydra-Lok differential or
other Spicer components, the bill of material
number must be checked. This number may be
found on a bar code label on the carrier snout
behind the pinion flange yoke, on a strip tag
between the bolts on the cover plate, or stamped
on the right axle tube when looking at the cover
plate (Figure 79). Figure 76
