Warning!
- Make sure the motorcycle is stabilised and adequately supported.
- A correctly supported motorcycle will help prevent it from falling.
- An unstable motorcycle may fall, causing injury to the operator or damage to the motorcycle.
Note: The input and output shafts may be removed from the upper crankcase after first separating the lower crankcase from the upper. The rear needle roller bearing on the input shaft remains in the crankcase on removal of the shaft.
Perform the following operations:
1. Lift the output shaft from the upper crankcase, noting the orientation of each bearing, their circlips and dowels.
2. Remove the selector shafts, forks and selector drum (see Selector forks and drum - removal).
Note: The input shaft bearing housing fixings may not be reused but should be retained for use during installation of the input shaft.
3. Release the three fixings securing the input shaft bearing housing to the upper crankcase.
