Left-hand crankcase half assembly
- Fit the 2 centring bushings 7x9x10, and install a new seal.
Seal is cut to size only after left-hand crankcase installation.
- Heat left-hand crankcase on an electric hob and assemble it.
- Screw the 7 TCEI screws.
Screws 4, 8 and 10 are M6x40; screws 5, 6, 7 and 9 are M6x35.
- Tighten screws (4-5-6-7) working crossways. Tightening torque 10 Nm /
1.0 Kgm / 7.38 ft/lb.
- Tighten screws (8-9-10) to a torque of 10 Nm / 1.0 Kgm / 7.38 ft/lb.
- Using a plastic hammer, gently tap crankcase at the bearings in order to
release any tension.
- Turn the two shafts to check that they move smoothly.
- Using a sharp knife, cut the protruding seal (11) flush with the edge.
- To prevent any damage to oil seal, wind some adhesive tape around output
shaft square edge (1).
Insulating tape should just reach the square edge in order to be eas-
ily removable after oil seal assembly.
- Slightly grease oil seal lip, and force it inside crankcase.
- Remove insulating tape with extreme care.
