GC 2300 hydraulic issues

[Fragger]

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.

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.

no DMW when I lift the 3 pt handle it does nothing to the actuator i will get some pics tomorrow..Thank you for your responses ;;
no cdaigle it comes out of the rear end.

I was unloading it from the trailer when it failed but cant see what I may have boogered up,,

DMW i do not believe we have the same pump here is a diagram of my GC2300 TRACTOR PRIOR S/N JNA25201 Login

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.

I wish I had been paid for all the times I took something apart only to find nothing wrong with it. You sure you’ve for sure identified the problem? Your suggested fix here sounds not so great. What do you mean by the Japanese are not cooperating? AGCO is not a Japanese company and AGCO is responsible for getting the Iseki parts. Sounds like it may be your dealer who is not cooperating. Tried other part sources?

Not sure what you mean by, "pulled the cover off the pump".

You mean disassembled the pump? Or, you pulled it from the housing, and inspected the shaft, and transmission gear?

The photo you posted, is labeled invalid.

Pulled it from the housing and inspected the shaft splines and the gear ll looked good neighbor who is one more French fry closer t o happy meal than me said probably had a stuck relieve valve .

 

[Fragger]

can anyone recommend a good repair manual with diagrams??

 

[irvingj]

Can't say it's "good," but the MF manual might be your best bet. I got a full set with my 2310 from the dealer when I bought it. I could help with pics of certain sections if you need it.

 

[ray66v]

I seriously doubt the existence of any independent versions of a GC2300 repair manual.

The only difference is the price, because of who you get it from, and in what format.

Thanks guys!!! ok it appears to be the 3 pt cylinder seal the tractor will drive I removed all the accessories and pulled the back off the pump; the gears splines and gears looked perfect compared to the last pump I pulled off. the fellow I talked to said if I could lift the3 point with no resistance then my seal was shot so I did and It is .
SO the diagram for the 3 pt cylinder would be appreciated if anyone has a good illustration.
