Oil and Chemical Type

Rear differential oil
Type: MAZDA LONG LIFE HYPOID GEAR OIL SG1

Sealant
Type: TB1217C or equivalent

WARNING:

The engine stand is equipped with a self-lock mechanism, however, if the rear differential is in a tilted condition, the self-lock mechanism could become inoperative. If the rear differential unexpectedly rotates it could cause injury, therefore do not maintain the rear differential in a tilted condition. When turning the rear differential, grasp the rotation handle firmly.

CAUTION:

Clean away the old sealant before applying the new sealant.
Install the rear cover before the applied sealant starts to harden.
Allow the sealant to set at least 30 minutes after installation before filling the differential with the specified oil.

Assemble in the order indicated in the table.
