Input Shaft

Input Shaft

• Removing and installing 3rd to 6th speed selector gears is described in chapter on disassembling and assembling transmission. Refer to => [ Transmission ] Transmission.

Special tools, testers and auxiliary items required

• Feeler gauge

Detaching needle roller bearing from input shaft and installing needle roller bearing onto input shaft





Removing needle roller bearing:

- Bend open needle roller bearing at separating point - arrow B - far enough for it to be detached from input shaft (do not bend open more than necessary).

Installing needle roller bearing:

• The shoulder - arrow A - faces toward splines for 2nd gear.

- Only bend open needle roller bearing at separating point - arrow B - far enough for it to be guided over input shaft and onto its seat - arrow C -.

Inserting spring in selector gear





The bent end of spring - arrow - must be hooked into hole in selector gear.

Checking synchro-ring for wear





- Press synchro-ring into locking collar and measure gap - a - at positions - A -, - B - and - C - using feeler gauge.

- Add measured values and divide by 3.

• The determined value should not exceed 0.45 mm.

Installation position of circlips





• The circlips - 1 - and - 2 - secure input shaft ball bearing.

Determining thickness => [ Determining circlips for input
shaft ball bearing ] Adjustments.

• The circlip - 3 - secures needle bearing for 3rd speed selector gear and 3rd and 4th gear synchronizing hub.

Thickness: 2.00 mm.

• The circlip - 4 - secures 3rd and 4th gear synchronizing hub.

Determining thickness, refer to => [ Determining thickness of circlip for synchronizing hub for 3rd and 4th gear ]

Determining thickness of circlip for synchronizing hub for 3rd and 4th gear





• Press synchronizing hub onto stop.

- Determine thickest circlip that will just fit and install it. For part no.

The following circlips are available:
