Engine/Primary Transmission

7

Fit the inner chaincase securing tab washers and set screws and squeeze over the locking tabs using a grip wrench as shown in Fig. C42.

8

Assemble the clutch location spacer, recessed portion towards the gearbox, followed by the spacing washer. The purpose of the spacing washers is to align accurately the clutch sprocket with the engine sprocket.

9

Assemble the engine sprocket and clutch sprocket to the triple row chain ready for fitting.

Offer the engine sprocket, clutch sprocket and primary chain as a set, feeding the stator through between the chain runs. The stator is still attached to the inner chaincase by the lead passing through the chaincase grommet.

11

At this stage push the engine sprocket fully home over the woodruff key, if necessary using a tubular drift to push the sprocket fully home. At the same time the clutch will need to be pushed home firmly over the splines of the mainshaft.

12

Fit the clutch centre securing nut and single spring washer (early) or nut and tab washer (late models) in the case of the tab washer engaging the ends, in the 2 holes in the clutch centre.

13

Loosely position the rear brake pedal and footrest, apply the rear brake fully and tighten the clutch centre nut. The correct torque for the clutch centre nut is 70 Ibs./ft. (9.678 Kg/m). Squeeze the centre portion of the tab washer to 2 flats on the nut (late models). Proceed to assemble the clutch.

14

If for any reason the clutch plates have been removed from the housing, re-assemble these, an inner splined friction plate first into the housing, followed by a plain steel alternately, finishing with the robust iron pressure plate.

15

The clutch diaphragm spring should be assembled to the spring tool and tensioned as shown earlier in Fig. C13 until the diaphragm spring is flat.

16

Offer the diaphragm spring on the tool to the clutch housing and push home as far as possible.

17

Enter one end of the clutch spring circlip and continue to wind the remainder of the spring into the housing as shown in Fig. C43.

When the spring circlip is well bedded into the housing all-round, remove the spring tool by slackening the centre bolt.

19

Fit the clutch push rod adjuster screw and lock nut.
