WD45 overcenter clutch

[RalphWD45]

4 yrs ago I split the tractor, and installed a new clutch in it. I put the 3/32" (or thereabouts) shims back in it, that were originaly there. After trying it out, it had excessive creep, in gear with the clutch released and I didn't like that, so I opened it up again, and added a .010 shim to all 3 points, closed it back up, and still had some creep, but it was better. Now the handle falls out of engagement, at the worst times, like loading manure on a slick surface, when stopping momentarily, means being stuck. I opened it up yesterday and pulled the 3 .010 shims out, and went back to work. It still falls foreward at times, and is only a little bit better.When I read about removing the shims to get more life from the clutch, does that mean that I should remove the 3 thick shims? Will the clutch still work, with those removed?

Ralph, in the manual there is a measurement that is supposed to be maintained for the slip clutch. I don't have my book here or I would give you the measurement. Yes you can remove shims to fix the problem. BTW the shims at each location should be stacked so you can adjust the measurement.

Leonard! where can I obtain shimms that I can stack, with the proper holes to fit? the 3 shims I made out of .010 stock, had rough edges to the sides, and holes. metal shears, and hole punches are not kind to shim stock!

Ralph, if you call Walter Implement, 509 982 2644, in Odessa they are available and can order them. Part numbers are 224542 or 226691. Ask for parts.

To adjust the clutch you remove as many shims as required to get the clutch to have a definite "snap" over center. Some creep is almost normal, especially when the oil is cold.

Leonard, if you still have the original shim packs in place, examine them very closely to see the individual shims. They are very thin and become very compressed over the decades. It may require a razor to separate them.

The service manual calls for a 0.065" clearance between the clutch plates at all points around the discs. This can be measured with a drill bit as a gauge.

The manual instructs to keep the clutch engaged when not in use to keep the oil squeezed from between the plates and minimize drag when the 80W oil is cold. Since the WD45 squeezes three pairs of plates in the space that the WD had only two, it is common to find the drag with high viscosity or cold oil.
