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 ( )

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)
