My latest tool project. This came from a machinery dealer, I was thinking there would have been less effort to get it going, but.... It was made in 1966, there is that.
The bearings were dry, well... Took it apart. This machine was mostly pressed together, getting the shaft out was going to require a press. I didn't have new bearings so the next best thing was to wash out all the old grease. Drilled a hole in the top and bottom of the shields and then washed the old grease out with PB Blaster, final clean with brake parts cleaner. Everything turned nicely so, re-greased them and sealed the holes with RTV. The idler pulley was pressed onto the shaft, it needed to be pressed off and then back on after greasing.
Somewhere in it's life the motor had been replaced and the pulleys didn't align anymore. Needed to cut slots in the mounting plate so the motor could be slid back. The drive belt was cut almost thru, ordered a new one. Because of the miss alignment of the pulleys the sanding disk shaft stuck out thru the sanding paper, that's not going to work. Getting the motor in the correct position fixed the shaft issue. Also meant the belt wouldn't drag on the sides of the stand and cut itself.
The wiring was interesting as the ground wire was not hooked to anything. The chord cap was hanging on by just the wires and not the strain relief. Install a new cap and chord, also hooked up the ground wire. So much for the machinery dealer checking things out.
Bought a wheel cart so it could be moved around the shop easily, seems to be working to my satisfaction. Most would never go to the trouble or effort to restore these old machines, they will go the distance if given a little service. It's fifty eight years old, should go another.
