Cannon Pinion Tightening Tool

[Waggy]

I also have the bergeon thing, still getting to know it and what works best. Used it in anger 2 or 3 times with mixed success. Last time I used it I think I over did it and the cannon pinion was too tight, I tried opening it back up with a smoothing broach, but didn't feel 100% correct when manipulating the hands. Anyone have a better way to fix this?

Bergeon 4733 Tightening Tool: This is a more affordable option compared to the pliers type, and it still provides good control and precision for tightening pinions.

All the cannon pinions i have seen have the detent on both sides, i would assume to keep it central to the center wheel arbor. Be sure to tighten at the same position and use a restricting rod inside the cannon pinion to prevent over tightening, carefully broach out if that happens.

Excellent. Thankyou very much.
