When I raise the loader it goes very slow up and slower down, to drop a foot it might take15 seconds. If i use the bucket valve with the loader valve it raises and lowers normal speed. I also here some flow noise from the valve like a relief valve is open. Can these valves be rebuilt, where is the relief? looks like a job to get it out so want to make sure its the problem.
Fixed, the aux valve was open
I have a similar problem my bucket goes up when I raise the rpms above idle ,then it stays up and won't come down almost like the linkage is jammed but it's not. Any help would be great as the wait time to get this t300 into the shop is a week to ten days
