Disassembly Notes





1. Mount retaining plate 9282 in vise, fit input shaft and undo hexagon-head nut with Special Tool 9105.
2. Use a suitable tool (e.g. Kukko 17-1) to press all parts off the input shaft over the 2nd gear wheel.

Assembly Notes





1. To inspect synchronizing rings, press rings onto the gear wheel tapers and use a feeler gauge to measure gap "A".
- Assembly dimension:
New: 0.9 mm minimum
Wear limit: 0.6 to 0.7 mm

- Transmission shafts without recesses for securing the hexagon nuts have been installed since September 1995.
- Self-locking hexagon nuts are used on these shafts, and these nuts must always be replaced in every transmission repair.
