Might seem a little weird, and a long shot to boot, but here goes.
Got one all apart, needed to have the flywheel and pressure plate turned. Flywheel is back on, had to tear the pressure plate apart to have it turned. Ready to put it back together, but can't find the spec on setting finger height. I know it's got to be done with the clutch assembled on the machine, (495 cubic nch 4 cylinder cummins in a 1960 road grader), but we can't find the spec. Guy that's helping says 5/8 of an inch rings a bell, but he's not sure and we can't find a paper trail. Got specs on everything else, springs and the whole nine yards.
Anyone??
