Clark C500 SERIES:
Steering cylinder blowing fluid only at max turn.

Hi guys, I just joined here. I have a Clark C500 45 lift truck Serial # 355 2553 2560. I have never had a problem with the steering cylinder before but now when I turn all the way to where the steering stops and the cylinder is at it's shortest it will blow fluid out of the rod seal end with great pressure. No leaks at any other position. I pulled the cylinder and installed new rod seals but I still have the same issue. I do not understand why it blows out as the seals should keep it contained at all times as long as they are i good condition. The rod is not under size with no scoring. Any ideas as to what may be going on with my truck? Thanks for any help you may provide.

Better to do it right the 1st time then doing it wrong many times.

that is a pretty old truck. you should mic the end of the ram and make sure it is not worn down. and do a pressure test on the steering check relief pressure

I had the cylinder out to replace the rod seals and found no cracks on it anywhere. It blows past the seals as if it is way to much pressure but only at the end of it's stroke. With the new seals in it I never thought that would happen.

Could there be a crack in the end of the cylinder tube where the seal fits or near that area?
