1. Remove rear caliper and hang out of the way
2. Remove rear wheel axle nut and adjuster nuts, and disc (Shop manual section 7-12)
3. Remove sprocket nuts (x6) with wheel off bike ensuring nuts are loosened in criss-cross pattern around the sprocket. Remove sprocket NOTE ORIENTATION
4. Remove shaft, spacers, rear dust seals and bearings; use long screwdriver to tap out bearings making sure to tap around the bearing evenly when pushing out otherwise inside of wheel can be damaged or bearings become stuck (at an angle) in the wheel.
5. Apply lithium soap base grease liberally to axle, bearing and a bit around the seal lips.
6. Replace bearings; use socket of just 1 or 2 mm smaller than the bearing outer race diameter and use this to gently tap the bearing into place. Insert new dust seals.

6. Fit new rear sprocket (noting correct orientation) and reassemble rear wheel components remembering to use criss-cross pattern when tightening sprocket nuts. Sprocket nuts to 60Nm. Put wheel to one side
7. Break chain with tool using correct pin size to ensure pin travels through link hole when pushing pin out
8. Remove gear selector MAKE NOTE OF NOTCH MARK LINEUP
9. Remove the front drive sprocket cover (4-2). Remove cover nuts in criss-cross pattern around the cover. Remove cover gently so as to be able to reuse gasket.
10. Remove sprocket nut and washer (NOTE ORIENTATION). To assist removing nut place wood between the wheel to prevent shaft turning; use wood that is not hard so as to mark the wheel. Use wrench or socket with pipe or extension attached so as to gain max leverage. Whilst applying tuning force push down on the shaft end of the socket/wrench.
11. Fit new UPGRADED sprocket and nut/washer (USING CORRECT ORIENTATION) kit
