Reducing Cannon Pinion Clutching Pressure


Recommended Posts

Hi , Connection problem, so preveois post was short.

If you are talking of excessive friction between canon pinion and it's  driver wheel, normally no more than  oiling ( tiniest bit)  should do, however, if the tube section of canon pinion is sqeezed /damaged so much to make contact/friction  from inside of the tube, I would vote for replacement. Plenty of eta 2836 parts on various sites.

The tube of the pinion isn’t damaged but it seems to be excessively tight where it is attached to the driver wheel. It is so tight that the minute wheel will pop off if I attempt to use the setting wheel.

I will take the whole assemble off and see what I can see when I get the time.

Thank you for your considered input. It is appreciated.

I wonder if there is maybe a build up of oil oil or corrosion in there. You could try polishing it with an abrasive like autosol or brasso and then thoroughly cleaning before lubricating again. Or just buy a new part for £5.

Hi Joe

I took it out and it was full of crap. I cleaned it and put some grease on it and it eased it a lot. I am cleaning it again and I will grease it again and put it back and see how it goes but it turns MUCH more easily now than it did before.

It took a x15 loupe to see all the filth!

    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
    • Isn't that the same guy who told Zelenskyy to escalate the war with Russia/Putin when they already had a peace deal? 2 years later and we have half a million young Ukranian boys dead. He doesn't seem very clever...
    • Thanks guys.  quick question. For automatic movement, particularly this one. can I power down the main spring by pushing this rachet down?  i've gotten pretty used to SW210 and powering down a manual movement. But so far i've only been waiting for the auto movement to run out of juice before opening the case.     
    • @Murks the problem you have mate is most watch cases out there to buy are for Seiko NH3X, ETA 2824 and maybe Myota 8XXX movements, oh also the big ETA 6978/9 movements which the dials start around 28.5mm. You might find one on a Google search but I suspect your main chance will be buying cheap quartz ladies watches and hopefully find one of the right size and condition that is acceptable. 😞   Tom
    • The anchor pin should be perpendicular when the anchor is sat on a flat surface and if you post a close up picture of the backplate I will be able to tell you the correct torsion spring , running fast or slow is usually wrong Torsion spring. Here is a video from my YouTube channel showing how I set the beat
