There are NO external leaks and NO loss of fluid in the system, so I guess it's time to start trouble shooting to find the internal bypass.  Following some previous postings on the issue, it seems that if it's not the cylinders, then the next logical place would be the dump valve.

At first glance it looks like getting the dump valve changed out could be quite a job.  Anyone that's done it recently care to share some Helpful Hints?

It looks like the only way to get to it, is by disassembling the throttle quadrant, even then it looks tight?

Any advise on that or general trouble shooting advise for the hydraulic system would be GREATLY appreciated!
