Observations on a motor rebuild
Posted: Thu Jun 13, 2019 9:16 am
I have a VV-300 I got for free last week that had a spring slipping so I disassembled and cleaned all the parts. I saw someone tried to repair a broken spring in the past and the spring had simply slipped off the post, so I refiled the spring hole and now I'm back in business. It was also missing the ball bearing for the spindle. When I received the machine the speed knob was turned all the way in to get the correct speed. After cleaning all the parts in kerosene, greasing and assembly I did a test run. What a difference it made!
When I assembled the spring barrels I use a brush to grease the springs as I install them. One rotation installed, apply grease and continue with this method. A little harder this way as the springs want to pop out but it alleviates the need to over grease initially after assembly and allows the springs to be pushed in flush easily.
