M41 and J type OD bench test. 120-130

Since I have a M41 laying around and I want to find out the condition of the OD my plan is to rig up a motor (like the ancient one I have turning my grindstone and wire wheels), put the tranny in 4th and then apply 12 V to the solinoid through the lockout switch.
Can anyone tell me why this would not work or offer any advice and/or precautions?
Many thanks.

The big precaution is that you DO NOT engage the OD while turning
backward! This can (according to quite a few sources) cause serious
damage.

Check out this site. Definitely one of the best I've ever seen for repair/trouble shooting the J-type.

Got that RIGHT! This is a GREAT writeup. Should be required reading
for all that work on J-type ODs, maybe even Duane (ODGuru) Hoberg!

I would think that ideally you'd want to have a load on it to test it properly. To be honest, I think it would be faster just to put the thing in a car, drive it and see. But maybe there is some way to bench test... I've never tried it.
