oliver rear pto shims.

Wes Verbal · Dec 14, 2016

Well another aggravating pain. I was running my 77 pto the other day and noticed when i disengage with lever the pto will stop but slowly start to rotate again and ceazy clacking and rubbing noise comes from inside housing. So.... that being said, i removed housing looked at the clutch which seems ok? 😦 the collar seems tight and moved on to the clutch discs and shims. I removed bolts and few shims on all 3 spots to see if clutch needed tightening.i have no service manuel yet so not very sure ? How thick should the clutch disc be or how thin until they need to be replaced?

The shims are used to adjust the clutch, you remove shims to tighten the clutch. Don't throw the shims away! They are expensive! How much snap does it take to engage the PTO clutch?

There are three tiny springs that separate the plates. Did you find them? I'm assuming it's the same clutch as the 50 series.

Yeah i kepts the shims ha. I took the clutch collat fork off it seems little looses ? How much play should they be in the clutch fork ?

The fork shouldn't matter. Once it goes over center and engages,the fork just floats.

The only 50 series that is like that is the 1550 without the dual speed PTO.

Ok. So... how to tell hiw worn the clutch disc are? I will post photos later of it apart.

I don't know what the minimum thickness would be. They have to still have facing on them is all I can say. Add or take out shims until the lever causes the clutch to firmly snap over center.

Ok.... ill tinker with it and see what goes😷

Here's a picture of new discs. Maybe you can compare it to yours.

John Schoenauer · Dec 16, 2016

Should there be the same amount or thickness of shims stacked on each spot?

Thanks John

When I replaced the PTO plates in my 1550 gas I had just the opposite problem,I had to get another set of shims out of a parts 77 to make the new plates work apparently they were thicker than the
original ones.
