[GreenKeys] M28 motor won't start

[Steve Ripper]

Duncan:

Part number 122245 = FSC (Federal Supply Code) 5910-00-184-3773.
The exact replacement can be found if you use the FSC part number.
I found several places that listed them as available, but no price provided.
I suspect that most of the sources will want a small fortune for the exact
replacement.
This site has the physical and electrical specs.

Suggest using this information to help you locate a suitable (cost
effective) replacement.

The AWA Museum has a M28 KSR who's LM3 motor does not always start - just
wiggles a little. If you reach in and give it a push, it then runs OK.  I
assume the problem is either the motor start capacitor or the relay
contacts.  Is either one more likely to fail??

Could the relay contacts just need cleaning?

Bul. 295 says capacitor is #122245; 43-52UF.  Any suggested sources for the
starting capacitor? Grainger has one, but looks like it might be too big in
diameter.

Thanks,

Duncan
