I recently aquired a Colchester Chipmaster, it had a very noisy variator. I got quoted a small fortune to have it refurbished, so i fitted a VFD and left it at that. Or so i thought.....
Curiosity got the better of me and I called in a friend to help me strip it so we can both see how it worked.
So opening up the cover plates we found most things in order, except for the "drive cones" that had a severe groove with a rough surface on the running faces. .
Next up was the balls, which were actually in great shape, the photos look a lot worse than the actual surface
The Cover plates and outer bearing race was also in very good nick!
I think this Variator was ran for a bit with a low oil level
Thats why everything except the drive cones is still in very good condition
Well, it helped me get the machine at a good deal
Next we made a arbor to mount the drivecones on with a push on fit and used the tailstock with a hollow centre to keep the drivecone on the arbor.
