Note:

Drive pinion and hollow shaft can be removed
complete if the 6th speed gear can be easily
pried off.
If it is necessary to press off the 6th speed
gear, the drive pinion must be pulled out of the
hollow shaft.

- Remove drive pinion circlip.

Note:
Carefully protect bearings from dirt, clean if necessary. - Pull drive pinion out of hollow shaft -D-, when doing this catch tapered
rollers -A- (Qty. 23).
- Take off corrugated spring -B- and needle ring -C-.

- Check bearing to ensure it is complete:
1 - Flange ring (tapered contact surface to tapered rollers)
2 - Tapered rollers (Qty. 23) with larger diameter facing towards drive
pinion head
3 - Support ring (tapered contact surface to tapered rollers)
4 - Corrugated spring
5 - Circlip for tapered roller bearing for drive pinion

Note:
Because of the type of fit, it may be possible to press gear off easily. - Press off 6th speed gear.
- Take hollow shaft or drive pinion and hollow shaft with selector rod and
selector fork for 1st and 2nd gear out of bearing plate.
