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

    • Good to know that Oldhippy is fine.  I wish you a fast recovery, we, the noobs, miss you a lot.
    • Managed to clear the short, cleaned and oiled the movement. Now testing for 24 hours before I case it up. The movement is so small that it's loose in my smallest movement holder.
    • @oldhippy - wishing you all the very best of recoveries
    • Looks like the kind of message that occurs when there are routing issues between your local network and the remote server the site is living on - there can sometimes be 20 or 30 hops and when there are issues some of those hops become unavailable temporarily for some people but for others where there is a different path being used the issues are not manifest. Another explanation, and this used to happen to me a lot with my ISP, is using the ISP DNS servers on your device or router sometimes is not as robust as changing to a public service such as 1.1.1.1 or similar. I was having a terrible time watching Youtube a while back - changed the DNS on my Apple TV to use 1.1.1.1 and problem solved. However, these issues tend to resolve themselves fairly quickly.
    • As mentioned by the other members, it’s a dismantle job clean and inspect the solder joints. It’s an older generation using the paxolin pcb  not the glass fiber ones.
