9020 with low hydro power

I have a 9020 with low hydro power.  When I go up a hill or pull something the hydro near the hand control seems to wurr faster like it’s over reving.  The fluid in the rear end is up to level.  Any idea what could be causing the lack in power.  I really think the problem is near the hand control.

The charge pump on your Hydro needs a doctor.

If your lucky t he shear pin broke, cheap fix. If the pump gears are worn you'll need to replace them and there might be some scoring into the case that needs to be resurfaced.

Will the rear 3 point lift a load.

Here's the repair manual.

Where is the shear pin located?  I might as well start there.  The three point hitch works good.  It lifts 200 pounds well.  AKA me.

If you would kindly download the Sundstrand repair manual from this link I've provided it would save me from having to print individual pages as pdf files, then importing them into an image manipulation program to export them as a png image file to upload to the forum as an image file.

The forum does not permit uploading pdf files.

Again here's the link to the Sundstrand repair manual, everything you need to know on that Sundstrand is inside the repair manual.

As it turns out I needed to adjust the clutch. The clutch wasn’t allowing the clutch to fully engage which caused a slipping belt = loss of power.
