1. Set the reduction gear component on the two 

blocks as shown in the figure.

Note

• 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.
