Reassembling the crankcase halves
The crankcase halves must be in good condition and perfectly clean. The mating surfaces must be perfectly flat and free from burrs.
Reassembling the clutch-side crankcase half (13)
The following parts must be present on the internal side of the crankcase half:
-
the secondary shaft bearing (17): apply grease on the bearing rollers. Fit the inner race (N) removed previously from the bearing. Apply grease to the inner race;
-
the primary shaft bearing (21), secured with screws (31) and retaining spacers (32): apply recommended threadlocker to screws (31), and tighten them to a torque of 10 Nm (Min. 9 Nm - Max. 11 Nm);
-
the roller bearing (19) with circlip (33) installed in correspondence with the end of the timing layshaft.
Reassembling the generator-side crankcase half (12)
The following parts must be present on the internal side of the crankcase half:
-
the double race ball bearing (16) supporting the selector fork shaft. If removed, apply recommended threadlocker on screws (34). Start screws (34) with retaining spacers (35). Tighten screws (34) to a torque of 10 Nm (Min. 9 Nm - Max. 11 Nm).
-
gearbox primary shaft end bearing (20) with inner spacer (22): apply grease to the bearing rollers. Fit the inner race (R) removed previously from the bearing. Apply grease to the inner race.
-
the main bearing (14).
-
the ball bearing (18) with circlip (33), in correspondence with the timing layshaft, aiming it so that the closed side of the plastic roller cage faces the crankcase half.
Note
Bearings do not have a specific mounting position (except main bearings), however it is good practice to install the bearings so that side bearing with the writing is facing upwards.
