BSA 120 Camshaft removal.

Hi, I'm currently stripping down my 120 and I'm stumped about removing the cam shaft, does anyone have any tips about getting the retaining washer out of the crankcase?

Searching for 120cc BSA rings, and found this, yes I've removed the cam shaft, carefully drove the shaft out from the other side of the engine, but be careful to stop the retaining washer from flying off. I just put some masking tape over it.

Not sure I understand the "....and found this" ?  If you are still looking for rings try

Thanks Paul, I put the post up at the end of December, then forgot about it, then searching today found it and replied to myself. Our local supplier of BSA bits and bobs, cannot get rings as his New Zealand supplier is shutdown with the CV-19. Thanks for the lead as I have the BSA and a Lister Diesel stripped down, and I'm looking for something to do, but I don't want to strip down my Lister D and have three engines in pieces waiting on parts. Thanks again and keep safe.

Paul, Good contact for the rings, we have swapped e-mails a couple of times and as of tonight the rings are ordered, thanks again much appreciated.
