REASSEMBLY

Caution1. Never reuse the gasket, O-ring, oil seal etc. Always replace with

a new one when reassembling.2. Never use grease other than blue petrolatum jelly and white

Vaseline.3. Apply ATF to friction components, rotating parts, and sliding

parts before installation. Immerse a new clutch disc or brakedisc in ATF for at least two hours before assembling them.

4. Never apply sealant or adhesive to gaskets.5. When replacing a bushing, replace the assembly which it

belongs to.6. Never use any cloth gloves or any rags during reassembly. Use

nylon cloth or paper towels if you need to use something.7. Change the oil in the cooler system.

(1) Use the special tool to tap the differential bearing outer race in thetransmission case.

(2) Use the special tool to tap the differential bearing outer race in the

transmission case.(3) Install the used spacer and snap ring.

(4) Install the low-reverse brake piston, return spring and one-wayclutch inner race , transfer drive gear , O-ring, spring retainer.

(5) Use the special tools to install the snap ring.
