To remove the clutch assembly from the gearbox mainshaft the clutch holding tool (8017) should be used to lock the clutch. The arm of the tool may be locked against the frame or the alternator rotor, but not against the gear cross-over shaft. Loosen the clutch nut (32mm RH thread) to release the clutch inner drum.
The alternator must be released to allow the starter sprocket to be lifted off, should it be required to remove the clutch outer drum. The alternator rotor nut should be removed while the clutch tool is in position (32mm LH thread). Cheek the condition of the bearings in the clutch outer drum before refitting it. This drum fits on the shaft without any spacer behind it. Should the bearings need to be renewed, remove the circlip from around the smaller of the two bearings and press both bearings through from that side.
To remove the starter drive release the alternator rotor nut, see above, and pull off in turn the alternator rotor, thrust washer and sprocket assembly. As the sprocket is removed the chain and front sprocket will pull from the starter bearing plate.
Within the large starter sprocket is a needle roller bearing, which runs on a sleeve which is a push fit on the crankshaft. It is not necessary to remove the alternator feather key to remove these parts.
