slipping splitter valve

[msjanket]

I had to put a new engine on my 10 year old splitter today. Same size, etc. I revved it up some and noticed that the return handle would not engage and stay in place. Instead, it popped shut and the piston stopped going backward. I think I was running more rpm's on the new engine that the other one which appears to have been running slower, even though "flat out". Is my control valve adjustable to this new rpm level such that it won't pop out when I try to put it in the reverse position and have it stay there until the piston goes fully back? thanks, all

I think you have the problem figured. They kick out in response to pressure. If the kickout pressure is adjustable, bump it up a bit and it should cure the problem. If not adjustable, look for any restrictions that can be reduced. How heavy is the oil you are running?

Voila! i tighted up the adjustable fitting on my Prince valve and now it works great. I can use higher rpm's, get more gpm, faster return, and no tripping of the valve detent prematurely. It's a win-win situation. I plan to get a pressure gauge, insert it between the pump and valve intake, and make sure I don't exceed hose or valve/cylinder pressure limits.

That kick off setting should be independant of the main system pressure relief valve but a gauge is a good idea. No use having the kickoff set any higher than you need.

Might need to do something similar on my valve. I added another Bobcat and the new one has hi-flow hydraulics. Makes it nicer to split, but doesn't want to stay. I have to manually hold it. I appreciate the input. Didn't even think about the change in pressure.
