open hydraulics

So this is an M100, cab tractor? Has a loader with mid mount cable controlled two spool valve under the right cab door? The hydraulic pumps are under the cab just below the seat? You have a gauge in the pressure line leading to that valve? The loader currently doesn't function at all? Yes/no so far?

Steering, PTO, and transmission circuits (all supplied by the other pump) seem to work okay? So what did the dealer shop claim they did to solve the original problem? You stated it worked ok after that for a while.

it first started having issues with the FEL, slowly creeping down . Took it into the dealer because I was just flat out busy , (huge mistake). Seemed fine at first then eventually it stopped working all together . I pulled the valve apart to find some parts missing (heater plug) . So I got a re seal kit and installed it. Still nothing .

What is the “heater plug” that was missing?

I hooked up my pressure gauge , haven’t been able to get much for pressure . When I ran the unit in the winter , I did notice sort of a wheezing coming from the pump area. It sounded like cavitation , so I checked my plumbing, new filters , all new oil . The pump isn’t making the noise now, so I’m wondering if the pump is cooked ??

Does the pump housing get significantly hotter than the inlet line to the pump?

Which doesn’t make sense because my 3P system works . I will see if I can put the 3P system under load to see if it can actually lift anything . Appreciate all the responses . Thx

I made the assumption that the 3 point working meant it was lifting a load.. so yes check to see if it will lift a load.
