Fresno Ideaworks, a maker space that I am part of has an Enco knee mill. It has similar problems with both the cross feed and the table lead screws: when cranked counter-clockwise, the nut holding the cross feed crank and the left side crank on the table unwind a little resulting in 1 or 2 turns of "backlash". Obviously this is not correct. On the table lead screw, if we use the tighten the dial nut so that the dial is rubbing on the table, everything is fine for a few turns then the nut will unwind and the giant backlash returns. The same sort of thing is happening with the cross feed lead screw and crank.
Looking at the Enco mill manual/parts list, it lists a couple of "adjusting spacers" in the bearing assemblies for both lead screws. I am guessing that these spacers belong between the thrust bearing and the sleeve that the dials fits on. Then the crank is positioned at the end of the sleeve and the nut is attached. The order of the complete assembly would be bearing, adjusting spacer #1, adjusting spacer #2, sleeve, crank, and nut, with the dial just riding on the sleeve. Unfortunately, these spacer seem to be missing for our machine.
My questions:
1 - Is my guess at how the bearing assemblies are supposed to go together correct?
2 - If so, what might these "adjustment spacers" look like? Are they simply flat washer?
3 - If flat washers what dimensions?
Any and all comments and suggestions will be greatly appreciated.

Bill F.
