Replacing gears on Singer T&S 635
The gears are slightly worn on my T&S 635 so that the machine will not sew. I have grown to really enjoy using this machine so I would very much like to get it fixed. I have found a set of gears that I believe will fit this machine on ebay but I do not know how to get the old ones off and replace the new ones. Has anyone on this board done something like that and would you be willing to show a few pictures of this procedure?
