What started this is......new 7.5 st
After unloading I noticed a tiny "knock" when turning
by hand. Not terrible by any means but it was there.
It spun good but a barley noticeable knock.
After bolting up and loading it with 2 space heaters
, one on each leg, I noticed the imbalance growl.
I have it apart now. The front bearing, sealed but with
the inside cover off and rolling around the shaft. It feels
OK but I will replace it. Back bearing seems fine.
The knock you ask ? One of the wound bibbins is a ltttle
loose on its mount...
