These Atwood camper jacks must be 9 years old now. One refused to budge today and using the manual crank was nearly impossible. I removed the motor off the head and the jack screw now works fine, so...
Good info. The motor is actually marked 75721 but Atwood told me the number had been superseded by 75625. And the cover is available as 87663.
I think I'll just buy a new motor and tear mine down for repair as a spare. Or if anyone can recommend an electric motor shop known to have experience with these, please fwd.
