Much hair pulling and a new valve, the issue remained. The cold weather by-pass i think was about 400 psi.With that in hand, and not knowing what could be causing it as i knew the basic path the oil took led me to believe the hydrostatic pump was messed with and mayby a bearing was replaced but the grease seal was left in still preventing the oil passing through it. I was told that it had an issue ever since a "hydraulic shop" worked on it and couldn't fix it, so it could have been anywhere.Long story short, the hydraulic pump has a small hole near the input shaft that allows charge pressure to come out of the pistom pumps into the gear pump, this hole was not present in the replacement pump. I drilled a hole into the housing, put it back together and it ran perfectly ever since.All of this took me a few months of fiddling, but eventually i got there. It was a basket case machine. The injector pump was sabotaged and one drive motor had dead Orings, it had no power on one side. $5 in Orings and it had all it's power back.</blockquote>
