AUTOMATIC TRANSAXLE AND TRANSFER ASSEMBLY


BUE051700000A09

Precaution

General notes

1. Select the adjustment shims, referring to Bearing Preload.

2. If the drive plates or 2-4 brake band are replaced with new ones, soak the new part in ATF for at least two hours before installation.

3. Before assembly, apply ATF to all seal rings, rotating parts, O-rings, and sliding parts.

4. All O-rings, seals, and gaskets must be replaced with the new ones included in the overhaul kit.

5. Use petroleum jelly, not grease, when assembling again.

6. When it is necessary to replace a bushing, replace the subassembly that includes that bushing.

7. Assemble the housing within 10 minutes after applying sealant, and allow it to cure for at least 30 minutes after assembly before filling the transaxle with ATF.

Warning
• Although the stand has a self-locking brake system, there is a possibility that the brake may not hold when the transaxle is held in a lopsided position on the stand. This would cause the transaxle to turn suddenly, causing serious injury. Never keep the transaxle tilted to one side. Always hold the rotating handle firmly when turning the transaxle.
