• To measure accurately, place only the idle
gear on the blocks and do not allow the
reduction gear component rotation part to
contact the blocks.
2. Holding the idle gear by hand, verify that the
preload scale reading is within the specification.
• If not as specified, replace the reduction gear
component.

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 subcomponent that includes the 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.
