Progress comes to he who battles on. Got the case off, and rebuilt the other side. The genny came to bits easily, and the ‘special tool’ listed to remove the rotor is not really needed. Just an M10 screw with 100mm of thread and the end reduced down to 7.5mm on the bench grinder. Impact gun the bolt in and the rotor falls off. Easy peasy.
So, do I strip the clutch down to free the plates or just chuck it together and hope for the best?
