Leaking hydro fluid Workhorse GT1800

Recommended Posts

Brand new member here, thanks for letting me in!

 

I have an old workhorse gt1800 that I inherited from from father in law. It has always had a small leak, you would have to add oil all along. Last time I tried to use it, it poured oil. I cleaned it up and looked it over best I could, put oil in it and fired it up and when I tried to use the hydro, it was just boiling oil out down in the hole where the lift lever goes in. There is one fitting down in there, its hard to get to and I didnt see it actually leaking but oil was coming from somewhere and I dont see any place else it could be coming out. 

 

I found some talk of that fitting on here on other strings and have decided that might be the worst one to get to on the machine. Does anyone have any advice for me about this leak?

Here's a thread with a LOT of information about GT1800s. 

 

 

 

 

Trina and I built this for friends. 

 

We've had several hydraulic leaks and

We've now chased them all ...

 

@cleat has several excellent threads on machines with your type of Eaton 1100 transmission.

If I'm understanding your post, the leak is in the steering tower somewhere near the spool valve. 

 

If that is correct, given how far you have to disassemble everything it might be worth planning to rebuild the valve and cylinder, and replace the hydraulic lines. Otherwise you might become overly proficient in disassembly and reassembling the tower and controls. :P

 

Just my opinion...

From your writeup I presume there is no leaking when the lever is not moved but there is a leak when it is used to raise a load. It could be the spool valve, a hose fitting, or a hose that is leaking.  Clean everything thoroughly and run the engine then gently tap the lift handle in the DOWN direction and see if there is a leak, if not give it a quick gentle tap UP and see where the leak is coming from.

I've not had hydraulic leak from 1800 but did on c175 Blackhood with kt17 engine. 

Removing the master hydraulic valve from inside hoodstand plus 4 hoses was brutal so I decided I was only going to do it once because I couldn't determine precise leak location...so i removed master valve and took apart and installed new O rings plus all 4 new hoses ...no leak thereafter...only had to do once....yippee! A bit expensive for 4 hoses but didn't want to repeat the job.....lots of bruised cut knuckles

The older models like the Electro and Charger weren't as pretty with the valve hanging off the side but they were easy to maintain.

Is that what is leaking on you. If so you could buy the fittings and a hose from Surplus Center.  https://www.surpluscenter.com/Hydraulics/?gad_source=1&gad_campaignid=18526732283&gbraid=0AAAAAo6yYyqtA3rKB1-xlS_ayELjfi1t0&gclid=CjwKCAjwiY_GBhBEEiwAFaghvocA81ohnTIMe1Fl3HB4-JoYyZ4JeF3XemwhGG3_EdfZ0mEGYstDORoCtJ0QAvD_BwE

More than likely, if it's at the valve, it's the fitting on the end of a hose. I had 2 blow off before I got smart and replaced all the hoses.

With the amount of work it takes to get that valve out, you only want to do it once! :omg:
