Hi I have gotten parts of the Willhoit band saw to come apart with penetrating oil and gentle application of the propane torch but I am stuck as it were at the bottom wheel and pulley. After carefully looking down the setscrew hole in the pulley it does look like it had spun on the shaft, not badly it rotates freely and I can move it axially about 1/16-1/8 inch but then it locks up. I also don’t have a three or even a two jaw puller and I can’t see where I could even get a grip on this since the hub is right against the base casting. The pulley is a zinc casting and I would rather not have to find a replacement or damage the bearings.
So my idea is to plug the keyway in the pulley (no keyway in shaft) find something that fits over the hub of the pulley like a piece of PVC pipe or a copper fitting and clamp it in place with a hose clamp and some thin rubber from a glove or wrap of newspaper. Fill the pipe or fitting with grease and with a reduced diameter tube attached to it and force grease in until it crawls off the shaft. I used to do this with my thumb to get clutch pilot bushings out of flywheels. Wish I had a grease gun I could just put a Zerk fitting on it and pump it off.
I already tried to remove the lower band wheel and ran into the same problem, that has a aluminum hub shaped like a top hat with the brim to the inside, when I started to move it the hub started to separate and I did not want to mess that up so I tapped it back with a wood block. I don’t want to press the shaft since I can’t see how the bearings are retained in the frame and it’s all cast aluminum.
Suggestions?
