PelPro 130b jamming problems

[little-willie]

Our PelPro 130B, which we have had for quite a few years, has been running fine until yesterday morning. We heard a loud snap, and soon the stove shut down. It had sheared the drive pin.
A couple of weeks ago, we had heard a "scraping" noise and vacuumed all of the fines out, the noise lessened but was still there some.
Back to yesterday, I tore it apart, dropped the motor out, and found that I couldn't manually turn the auger, even with a punch inserted thru the pin holes.
Removed the auger cover, cleaned it all spotlessly, found some play in the bushings, replaced those (I had some spares here), reassembled it, auger spins effortlessly by hand, installed motor and pellets, and it still jams TIGHT.
It will drop some pellets, but then jams tightly enough, that I can't manually rotate it by turning the motor body.
We have NOT changed pellet brands, and have been running the same brand for several years, burning over 2 tons, already this year.

The Auger motor you will not be able to turn by hand due to the gearing. It may be time to pull the auger itself out of the stove and verify it is “true”. Inspection of the auger feed Shute would be the next thing I checked, look for warn/torn sheet metal or wear of the shut/tube. Then look at the bushings to see if they are worn out.

I'm not trying to turn the auger MOTOR by hand, I was trying to turn the disconnected auger, by itself.
I had it completely disassembled, I replaced to auger bushings, but didn't rotate the auger on a flat surface, to make sure that it was running true and straight.
There was some scuffing on the chute cover, I wire wheeled them smooth and installed the cover "upside down", it seems to work much better now.
I will probably order a new auger.

To anyone interested, the problem appears to be wear on the auger and cover.
I smoothed the cover, with a fine wire wheel, then installed it upside down, and that seems to take care of it.
I will order and replace the auger, I haven't located a replacement cover, so hopefully replacing the auger will tighten things up enough to fix it permanently.
