I rebuilt mine with nos rust free shaft, gears and gaskets. The ground side of the idler gear is oriented towards the cover as per the book and payed special attention to all details. Once I got it all together it seems a little bit harder to turn than I expected. So I did it all over again and same thing. It's not rough but just in one spot on every rotation there is a 'high spot' -I don't know does this seem the norm until these break in or..?

You may need a thicker gasket.

You might try spinning it in a bucket of oil with a drill first and see if it frees up.

If it's a noticeable area, dress the high point down with a diamond dust needle file. A tiny high spot should wear in pretty quickly.

I ended up taking it back apart and finding exactly where the 'high spot' was and dressing it a tad by either scraping with the edge of my old tool box knife or a very fine file. It now spins true. The thing had apparently been bumped along an edge of one of the teeth in all it's years of sitting in the og paper wrap. I did put it in oil and run it and that was when I 'knew' something was definitely amiss. All is well now and thanks again:) freezerburn | | |
