I have a 2017 PowerStar T4.75 at work and have developed a pretty bad hydraulic leak at the remote valves on the back, it's a stack of 3. I can't really see exactly where the leak is coming from but I have a steady stream coming from behind the bottom valve. I've checked all the bolts that clamp the stack together and the bolts that clamp the port plate to the valve body and all are tight. I can't get any movement of the valve assembly by tugging on it, everything seems tight. I found a blow up diagram online and it appears the only points that could leak are the seams between the valve body stack and the plate that has the quick connect ports attached. Does anyone know of any other possible points?
My plan of attack is to first remove the port plates one by one and check the seals and then if necessary pull the stack apart and do the same. Any other suggestions?
The leak is a steady stream that has gotten progressively worse since first discovered, we ran it just long enough to drive it about 4 miles back to the shop. The rate is fast enough now to make an unbroken stream to the ground from the drawbar about 1/16" wide.
