Ford 600 pto issue

My father was out brush hogging and I just bought a overrunning clutch and when he tries to change from 2nd to reverse it grinds badly and will not go in. When the pto stops it will finally go into gear, is this how it's supposed to work? Please any suggestions.

ounds like roll pin installed wrong..center it.
 
Is he trying to shift from 2nd to Reverse while the tractor's moving? That's not a good idea no matter whether the PTO is engaged or not. Once the tractor has come to a complete stop he should be able to shift without grinding. If the brakes won't bring it to a complete stop with the clutch in and the PTO engaged, then the ORC isn't doing its job properly.

Did you hit it good with the grease gun once it was installed? The ratcheting mechanism needs to be well lubricated to do its job properly.
 
He says he stopped and tried to shift it but
it kept grinding when he tried to put it in
reverse, I greased the overrunning clutch
and put a bunch of grease inside so I know
that I greased it good.
 
All of my tractors have had live or independent PTO so I only know the theory behind an ORC and have never actually used one.

From what I understand, the ORC is designed to keep the implement from driving the tractor forward when you push in the clutch and apply the brakes. If it can be stopped by the brakes when you push the clutch in with the PTO engaged with the brush hog still spinning then it's doing its job safety-wise.

I guess when you shift it into neutral then there's almost no resistance to the PTO spinning any longer because all it's trying to turn at that point are a shaft and a couple of gears inside the transmission, so it could stop ratcheting and spin the shaft inside the tractor at that point. Although I've never heard of it before. Contact the manufacturer of the ORC ans ask them if that is expected behavior.
