Thanks to Rick Cavallaro for explaining and taking pictures (see PDF)
Disclaimer: I am NOT an expert mechanic. If something looks or sounds wrong in these directions, it probably is. I’d be happy to receive any tips or feedback on how to improve this (firstname.lastname@example.org )
Special tools needed:
- Circlip pliers
- Blind bearing puller
- Spanner and pinion holder (homemade – see Fig. 2)
- Arbor press (bench vice or drill press may suffice)
