Hi Larry - I remember the motor mounting plate having slotted holes for adjustment. You could also loctite the gear on the shaft.

I loosened both setscrews (at the key and 90 degrees away from the key), moved the sprocket back to where its hub was in line with the end of the motor shaft, and then re-tightened the setscrews. After running for about 5 seconds, the sproket moved away from the motor once again. I put as much force into the Allen wrenches as I could (I think!).Looking down the chain from the auger end, it appears to run at an angle, with the drive sprocket "out" too far. That is to say, the two sprockets (motor and auger) are not lined up with each other.The drive sproket was new a couple of years ago, purchased from either Jim or Harold, along with a nice new chain. It is possible that it has been rubbing against the housing for some time -- the unit makes quite a racket when running.That raises a few questions:1. Which way should the drive sprocket be installed on the motor shaft, with the hub towards the motor or away from the motor? (Mine is "away".)2. Is it possible that the motor shaft is at slight angle, not perfectly parallel to the rotational axis of the auger? If so, how do you get the motor aligned correctly?This is likely to be cold, dirty, oily, heavy work -- not fun at all! ;-)Many thanks in advance for any advice!Larry Chace, Ithaca, NY I-5 and E15_______________________________________________Elec-trak mailing listElec-trak cosmos phy.tufts.eduhttps://cosmos.phy.tufts.edu/mailman/listinfo/elec-trak |
