This seller on https://www.ebay.com has the whitfield auger bushing. I got one just to have on hand.
Replacement motor from GRANGER... $89 ! for many stoves including Whitfield.
Grainger's motor has
100in-lb torque and is much beefier (maybe 30% more coils and plates) than
the original, if eyeballing the size is valid. My Whitfield gear motor
electric wires are the same color; it does not matter which spade connector
is attached to either motor side, it is "60hz alternating". This motor is
not as silent as the original, but it certainly is a capable replacement. I
got to where I could take the motor on and off in less than 5min.
I did add a nylon washer
(to augment the blue spacer) to the shaft of the rotor on the old gear
motor; that did not help. It was a good tip to check it.
I did several things to
reduce the torque requirement, as in preventing the pellets from jamming. A
key discovery is that the auger needs a washer to get it as high up the
shaft as possible. The pellets would jam at both the bottom of the auger and
at the top of the augur. You need al the clearance you can get to prevent
pellets from being crushed by one mechanism or another at each end of
the augur. While the band-aids worked for a while, feeding was still not
reliable with the old weakened motor. I eventually came to believe that the
gearmotor was stalling due to a loss of torque, even thaough the torque felt
great when if test it against my own "hand resistance" on a bench. I MUST BE
GETTING OLD AND WEAK myself! I am not sure why aging loses torque as this
motor does not have magnets to degrade.
