JD322 Freewheeling

cef2lion · Jul 7, 2003

My JD322 going down hill runs away more than I thought normal. In my garage I shut it off and tried to push it and I could without much effort. I checked the freewheel valves and they were clean and not worn looking. I replaced all the O rings on them.

I bought the unit used in the Spring. I changed the hydro fluid and filter. I think it had still been using type F fluid. I switched to what Deere recommended.

I'm not sure if the tractor was ever towed without the freewheel lever engaged and what damage that could do? I was wondering if there is something else I might check to correct this or do I have a worn hydro unit? It operates ok in all other respects.

Just a thought, but perhaps the drive belt to the hydro unit is slipping? I don't know if that would cause the symptoms you describe or not, but it will on a gear drive (don't ask me how I know /forums/images/graemlins/tongue.gif)

The 322 uses a drive shaft and not a drive belt. I watch the drive shaft while I'm pushing it and it is not turning. The Tech manual says to check the freewheel check valves to make sure they are not sticking or have debris in them. I have done that so it has to be something else.

I removed and cleaned the implement and charge relief valves this evening. Afterwards I moved the tractor back and forth a bit pressing the freewheel hydro valves. All of a sudden I was not able to move the tractor unless I engaged the freewheel lever. It is working as expected now. Something in one of those valves I checked must have been where the issue was.
