![]() I cleaned up the bearing casting with worn scotchbrite. These bearings have a snug friction fit, but do not require any tools to remove/replace. Then I re-bolted the saw to the stand, and moved on to the next moving part, namely the lower wheel, shaft, and bearings. ![]() I could feel and hear the difference - much less vibration throughout the saw. This did 3 things: took up any slight "slop" in the base to mount connection, deleted the harmonic buzz, and provided a wee bit of isolation. So I loosened the motor mount bolts and slid some pipe insulation between the motor frame and mounts (taking a trick from building computers in which I never solid-mount a moving part to the case without isolation). However, the slight motor vibration could be felt throughout the stand and saw and you could hear a harmonic buzz. With the belt off and no sheave (the thing that looks like a pulley wheel) on the shaft, the motor ran very smoothly. ![]() The motor shaft spun very freely, with no wobble and play, so it seemed like the motor bearings were solid. Now that I had a stable platform to work from, I began looking for vibration in every moving part, starting with the motor. With only the motor and lower wheel turning, I could tell a difference. ![]()
