• Install the coupling unit within 10 min after applying sealant.

• Allow the sealant to set at least 30 min after installation before filling the differential with the specified oil.

1. Apply sealant to the coupling case surface that contacts the rear differential case.
2. Install the coupling unit to the rear differential so

that the two tabs on the coupling unit engage the
rear differential grooves (two locations).

Warning

• The engine stand is equipped with a self-lock mechanism, however, if the coupling unit is in a

tilted condition, the self-lock mechanism could become inoperative. If the coupling unit
unexpectedly rotates it could cause injury, therefore do not maintain the coupling unit in a tilted
condition. When turning the coupling unit, grasp the rotation handle firmly.
