Hello there!

please help! I’m stripping an as1950/51 movement,  and I’m stuck on removing the friction pinion from the second wheel. Can anybody suggest safe way to remove this? There is a small circular lip superficially but I can’t get access...how to proceed? What to use?

thanks everyone!

Welcome to the forum tony.

I check the friction on canon pinion prior to disassembly, specially these offset ones, as it might need a bit of tightening.

Remove the clip, the pinion should come off of the arbour with ease, some folks use a hand remover, some push on the arbour pivot and if you got a staking set you get a neater result, clean & clean , apply grease and reinstal. 

Good luck

Thank you for your introduction and welcome to this friendly forum.

If the wheel and pinion are working OK. I would leave it alone, removing it can cause trouble. If you have a cleaning machine it will clean perfectly well and as Nicejoe has said just apply grease, just a tiny bit and work it around or you can use a tiny jop of oil.

Hi Tony and welcome to the forum. It's nice to finally meet someone from the same profession. I consider myself semi-retired since the start of Covid-19. This pandemic has really wreaked havoc on Dentistry. It's no longer fun going in to the office anymore, especially when you have to don full PPE just to do a simple prophylaxis. And I do not think things will ever go back to normal.

Cheers and stay safe. :thumbsu:

 Thanks for your replies guys, really helpful.  I’m initially going to take a conservative approach as suggested and grease in situ if I can. I did check the hand setting before stripping down, and it seems ok...

cheers! TonyG
