I need to replace the hour gear on my president and can't find a 10an 21 jewel movement.
I assume you are referring to the hour wheel.
Order by height from Jules Borel and Co.
Around $10 and shipping.
the center-wheel pinion snaped off when i removed hr.wheel, Rusted together. So I will not be able to measure it. This 10an has an odd jewel for that sweeping second hand so I thought I'd get a donor and put the parts in this one. Can't find a 21 jewel though
A Font 1146 10.5L and a Font 324 both use that sweep center wheel.
I don't know about the cannon pinion , but you can get those. The hour wheel should be brass and after soaking, should come off and be usable.
Anyone know if there is a difference between the wheel for a 17J and 21J movement. Are they interchangable?
If it is for the sweep second version of the movement, it will be interchangable.
You must still buy a donor movement , as the parts are obsolete, but it expands your search.
The jewel for the second hand/dial (4th wheel) has a brass bushing surrounding the jewel. The 4th wheel stem is thicker to accomadate the sweepwheel.
There's nothing like a Donor for parts, you get what you need and have the leftovers for later on.
I'm learning all these parts names from The info provided in the info. catalogs here
Thank you my Bulova.
I also just bought a parts interchange booklet.
I'll check to see if I have a 10AN 21J parts movement.
I'll have a look at my collection 10AN's and see if I have a 21J.
I was able to get one that works ,using the interchang book. Great addition to my collection that book. Thanks guys
