Latest Update: I'm back up and running with the help of this forum and Loader Parts Source. Thanks Tazza for suggesting them. I worked mainly thru Don of LPS who provided outstanding customer service with lots of follow-up and updates thruout the process. Being a difficult customer with lots of...

Ok, there is some slight wear on the plate. Thanks, now I know where the issue is.

What I am calling the swash plate is the part that tilts back and forth by the operator control. The area where the most leakage is is where the shoes contact the swash plate. Although smooth, the swash plate does have smooth depressions which I'm guessing is the source of the leak. Although...

Got the machine apart, after capping off the main pump ports, tested each hydrostatic pump with compressed air in the charge oil port. This clearly determined it was the rear pump, as it passed lots of air, the front pump was almost none. Dissasembled pump, found the wear plate not too bad...

I have heard of getting this surface ground and lapped but had no idea that it had to be hardened again. Great information. I will get these pumps apart and contact Levi. To clarify the case drain vs the charge line in my case, the case drain is located on the main pump housing, it captures the...

Hi, it's been awhile since I posted on this and thanks to all who helped so far. To update, my oil temperature is staying very cool, staying below 125F. I did some case drain flow tests, which were all at idle, with warm oil. At idle, it maintains full charge pressure with no load...

For the most part, I just loose charge pressure and get more groaning when under load with warm oil. No noticeable loss in power though. I had one of the hydrostatic pumps apart to replace it's shaft due to the broken off piece of the hydraulic pump was "fused" in it. I didn't observe any...

Yes, no doubt I was lucky to have access to the another machine's auxiliary hydraulics to get the backhoe out of the ditch and folded up for transport! Looking back, I guessing I could have used the logsplitter (with the Briggs motor, not the cordless drill) to provide hydraulics to the backhoe...

The hydraulic pump wore out, locked it up, and snap the input shaft. The hydraulic pump is one of those deals that incorporates the charge pump at the other end, so when the hydraulic shaft broke, charge pump operation ceased. Besides lots of hours, I think I found the likely culprit for the...

Thought I would share this maybe some can add to it. While digging a deep ditch in a muddy area last fall with my attachment backhoe on my Hydra-Mac skidloader, I heard a loud bang and immediately lost all hydraulic pressure and the low charge pressure (for the hydrostatic systems) warning light...
