GC2300 hydrostatic issue

[not2old]

the less you press the hydro pedal, the more torque that is produced.

I learned something today

Where should I point him to look to pull the valves? We do have the service manuals and parts manual.

They are right at the front of the transmission section, pages 05-3 to 05-6. Probably some photos later on.

Good luck!

We aren’t trying to dig with the FEL. We just can’t move it forward. The FEL has only been used to help level off some of the area as it’s either been hand dug or with the BH. It operates perfectly fine under a cold temperature.

Yes, fluids are proper. Yes the fan works.

I can replicate everything in your video with my GC2300 with underinflated rear tires. Your backhoe is about 200 pounds more than my counterweight, causing more traction/compression on the rear tires not allowing them to spin. The angle of the FEL is directed into the ground, not sraping off the top layer of dirt. If it only happens when hot, i would suggest the tractor fluid being used. That high pitch whine is indicative of poor fluid (at high temperatures) and not the relief valve.
I always cringe when someone says they are using a suitable fluid. Youtube channel Amateur Homesteading posted a 50 maintenance video on a GC1723. They thought it suitable to use a hydraulic oil, and not a tractor hydraulic fluid. They are not the same, but it will work for a while. Don't believe everything you see on the internet.

Just a thought... has the suction strainer been cleaned?

I wondered also but wouldn't that also affect FEL and hoe functions as well as steering?

One VERY weird thing is the previous owner appears to have used RTV on one of the gaskets.

If this was the pump assembly, it may have been from the factory that way.

There are two hydraulic pumps.

If I am remembering it correctly, there is an internal pump is for the drive train, and the external pump operates everything else.

on my gc2400 the manual says steering pump is common with main pump, think that means main pump handles it.



this is all gc2400 service manual states about any pump in system



but with so many changes between gc23xx and gc24xx on wards who knows.

I could be wrong then, it's been a while.

The pumps were letting go now and then, about 20 years ago.

There was a factory defect, and they didn't do the right thing, and recall all the affected units.

just as possible there is difference between gc23xx and gx24xx and we both are correct
