| 32mm socket for the clutch centre nut and a 13mm on for the basket ones.
You'll need a holding tool as already suggested. Torque on the centre nut is 186Nm, the basket bolts are 33Nm(?) Use loctite on them all.
If you fit a slipper, depending upon brand, the new centre nut could be a 30mm jobbie. |
