I took a very close look and sure and behold there was a small bare spot @ 12 o clock in relation to the hub. I went to the hardware store and bought another washer to add to the one present. The wheel spins effortlessly. The second washer that was present must have been ground up when the blade came off now it s off to putting the blade on and tuning it according to Alex Snodgrass.

Gerald… what year is your saw? The reason I ask is that there should not be a washer on that upper wheel – although it is possible that a PO added it when swapping out bearings… The older machines used 87502 bearings, which have an extended inner race (which faces outwards when installed on the wheel). It is possible to replace them with the more common 6202 bearings, as they are the exact same width, bore and diameter but do not have the extended inner race – so to use them, you need to supply a washer to make up for the difference.

I’ve seen many times where people have taken those 87502 (and 87504 on the lower wheel) to a local supplier only to be given the wrong 6202 bearings as replacements. Then they wind up having problems like you describe, and can’t figure out why, since they are positive the ‘expert’ at the store gave them the right bearings ;-)

Cheers,
