Ok so about year or so ago I replaced the auxillary oil pump and last week the front end loader and the 3 point hitch quit working.:dance1: So I remember the last time the power steering also failed but it is still working so does anyone have any ideas what could be the problem.:confused:

Starting with simple checks-Does this GC2300 have rear auxiliary hydraulics added? Sounds like my GC2410 when I have the ear hydraulic hoses mixed up. Check all of your connectors for debris or ceased check balls.

Check the linkage for the 3pt. control lever that it still connected to the valve. GC2300.jpg

It's the [190] TRANSMISSION - POSITION CONTROL . If you still have hydraulics for the transmission and steering, your pump may be ok. The control valve pictured prioritizes flow. I believe transmission first, steering second, FEL/3pt last. If the linkage from the 3pt handle is not shifting the spool in the control valve, it may be stuck open, draining back to tank, so all pressure to the FEL and 3pt is lost. It's an easy visual check, tractor doesn't have to be on. All it takes is 1 cotter pin to fall out.
edit to include correct diagram. Arrow wasn't positioned correctly.

Man, that would be great !! after talking to couple of mechanics they seem to think my pump dumped on me ..I like your analogy though and when I get it jacked up p I will look into that and keep you updated..
Thank you for your advice and support:tractor:

Ok so here is what i plan on doing since the Japanese wont cooperate So I plan on buying a pump from Northern tools and attaching to the front PTO that normally would drive my belly mower .. Would come off the original suction line that goes to the original pump then discharge to the suction of the original pump. Any thoughts or knowledge if this would work ?? basically I would be hooking it in series with the old pump. It would be cheaper and not as hard to install. Thoughts and advice are welcomed !

If the old pump sheared off the drive gear inside the transmission, you still need to do a tear down.

At that point you might as well replace the original parts.
