2320 - How do i stop this leak

[thatguy]

Sort of thinking #25?

That was my first thought.. Then i realized that is a bolt.. My problem is a nut on a stud..

BUT it could be in the area #8 BUT its not shown on the diagram .. that looks like it may be in the correct area (below and to the left of the solenoid..

I think I stand corrected. If I really had to guess would would say #1??
Is your fluid level to high?

I have idea what part of the tractor I am even looking at there...

 

[ccsial]

Gasket (#7) has broached, permitting hydraulic fluid to escape via the bolt hole. Cheap part, expensive repair. Could have been defective since new, and just took some time and pressure to eventually broach. If you're no longer under warranty, I'd first get the tools necessary to remove the nut. Then buy (a) a rubberized crush washer and (b) some oil-resistant sealant. Sealant can be found at most auto parts stores, washer at high performance shop or motorcycle shop.

Apply the sealant, install the washer, crush it down with the hex nut. Remove nut, add lock washer, replace nut.

I would agree this is the most likely.

Thanks everyone.. Several have mentioned a gasket issue that is allowing fluid to escape..

I think I will try 'greg_g' suggestion and see how that works.. Assuming I can get that nut off..

The fluid level is about half a way in the window with the 3pt down..

Luckily the leak is not pouring out.. So I may just have to live with it and keep an eye on the fluid level..

thanks to everyone for all your time and efforts..

I would also agree with greg_g as a first defense and reasonable to try. Hopefully can do with a socket and flex joint. Before removing, I'd check the torque first to determine if it was just a loose nut. Then after greg-g 's plan, torque to specs.

Will be nice to not have the leak, as they just eat away at you when thinking about your pristine tractor.

Is all the debris under that floorboard from mowing? Would be nice to be able to blow that out (or does it just soak up the oil ? .
Wish you well and hope you post how it goes.
I think I looked at every page of the jdparts to try to help, but didn't get past what you already found.

I am pretty sure both #'s are referring to the same nut.

that nut holds the center plate to the transaxle case. there is no fluid pressure in that area(unless the case vent is plugged).
I think it might be somewhat common, as I think mine is leaking too.

 

[greg_g]

there is no fluid pressure in that area

Yes and no. Perhaps not pump pressure, but hydraulic fluid heats up with use as well. By simple convection, it then heats the air in any voids. Warm air expands, creating it's own pressure. Under these circustances - if there's a weak spot in a gasket - fluid will find it. This is also supported by that the leak doesn't present itself until after the tractor has been running for some time.

yes but it is vented to prevent it from pressurizing and blowing seals/gaskets. with the vent blocked just lowering/ raising the 3pt and or loader can blow seals out.

All that debris is from 300 hr of use - both MMM and rough cutter..

Before I put it all back together I am going to blow all of it off.. I was shocked at how much was around everything.. I need to use the leaf blower under the floorboard way more often that I have (ie never so far).. lol

Still planning my attach of the oozing nut.. Trying to locate a local place to get the rubber crush washer and such before I get too much into it.. BUT I also thought I may run by the JD dealership with the parts diagrams and get their thoughts..

Does anyone see any future issues if I decide to NOT try and repair it? I hate the idea of it leaking, but its so slight I can live with it.. I was really worried that I would find something broken when I got it aparts, its a relief to know that its nothing major..

thanks

Stuff a rag in there so the oil doesn't drip on the floor, and change the "diaper" once in a while.

UPDATE - Well i picked up a set of universal joint sockets yesterday and played with it a little this afternoon.. It is such close space even the 1/4" universal was too long.. I can get a socket on the nut there there is NO room behind it to get a rachet on it.. :-(

I also tried a wrench on it.. You cant even get the socket end on the nut, but you can get the open end on it BUT you can swing the wrench <1.5" at a time if i got it loosened up..

So it appears that unless I take a lot of other parts off I will just have to live with my leak.. I am taking some time off tomorrow, so I will keep playing around and see if i can figure out a fix..

thanks for all the help

Rather than a rubber washer, I would use a copper washer commonly used where brake hoses bolt to brake calipers with a banjo bolt. An Auto Parts store should be able to match to the size you need.

Good luck with the repair. Looks challenging.

 

[thatguy]

Zebrafive - I was at AutoZone and saw those copper washers and wondered if they would work

BUT - I messed with the bolt again this morning and due to the limited access to the area, I just buttoned the tractor back up and will just live with the leak until it gets worse..

Somehow I ended up with 2 bolts from the dash area left over.. oops.. I do know they are from that area because I kept them together..

thanks for all the help.. I really appreciate the brain trust TBN offers..
