Just did a vid on replacing the bandwheel bearings. I noticed a vibration as I sped up the mill, and as it came back to a stop ... like something was wobbling. I guessed that it was the non-driven side. I was right. Haven't run it yet this season, just did this a couple days ago. Need TWO bearings per bandwheel. SKF 6305 2RS 1C3 is the part you need.
gonna post this in the general sawmill forum too
