Fig 12: Identifying Input Shaft, Drive Pinion, Relay Shaft, Shift Rods With Selector Shaft And Selector Forks
- The input shaft -A-, drive pinion -B-, relay shaft -C-, selector rods -D- with selector shaft and selector forks -E- must be carefully pulled out together.
Installing
NOTE:
If input shaft ball bearing, input shaft or the transmission housing are replaced, it is necessary to re-determine the thickness of circlips for input shaft. Refer to
Input shaft, adjusting , adjusting input shaft.
- For easier installation of following components, swing transmission housing into the position shown.
Fig 14: Assemble Input Shaft, Drive Pinion, Relay Shaft, Selector Rods With Shift Rod And Selector Forks
- Assemble input shaft -A-, drive pinion -B-, relay shaft -C-, selector rods -D- with selector shaft and selector forks -E-.
- Install these components together into transmission housing.
NOTE:
Relay shaft -C- and selector shaft can also be installed later. Refer to
Fig 17.

4 - Relay shaft
5 - Detent mechanism
6 - Selector shaft
NOTE:
Shown in illustration with input shaft and drive pinion removed.
- Turn transmission housing and engage 3rd gear (direction of arrow).
- Install relay shaft -A-.
- Insert selector shaft -B- sideways into hole in transmission housing and assemble into mounting eye.
- Turn the selector shaft in direction of arrow.
