Refitting the alternator-side crankcase half

The following parts must be present on the internal side of the crankcase half: the double race ball bearing (9) supporting the selector fork shaft. Apply threadlocker to the screws (11). Fit the retaining plate (10) to the gearbox secondary shaft bearing (9) screwing the screws fully into the chain-side crankcase half (11).

Note

The bearing retaining plate must be positioned so that the countersunk side is facing upwards.

Tighten the screws (11) to a torque of 10 nm (min. 9 Nm - max. 11 Nm) (sect. 3 - 3, Engine torque settings).

Lubricate the ring (6) with denatured alcohol, drive it fully home against the crankcase half, and orient it as shown.

The primary shaft bearing (7) with internal spacer (6), oriented so that the closed side of the plastic roller cage (m) faces The crankcase half: apply grease to the bearing rollers. Fit the inner race (a) removed previously from the bearing. Apply grease to the inner race.

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 the writing is facing upwards.

Fit the mesh filter as described in sect. 4 - 3, Changing the engine oil and filter cartridge.

Important

To avoid damaging the filter, insert it by hand only. Do not use hammers or other metal tools.

Above the mesh filter seat there is a plug (19) which closes off the lubrication oilway. If it is to be renewed, apply the prescribed threadlocker to its threads.

Tighten the plug to a torque of 24 nm (min. 21 Nm - max. 27 Nm) (sect. 3 - 3, Engine torque settings).
