BH puking fluid SOS

Stokes760 · Aug 11, 2013

Back round Kubota B7800 125 hours BH75. Took the tractor over to a friends to dig out a few things. Noticed the left stabilizer was stiff to retract messed with the valve didnt happen again didnt think anything of it. Fast forward just over a week went to get tractor off of trailer and found puddle of hydraulic fluid under tractor. checked around 99% sure is from bh. checked lines seem tight couldnt check inner lines with out removing outer lines. Think the leak from valves sense they were covered in fluid aswell. Fired up tractor to check left stabilizer was so stiff to retract plastic lever snapped off. Also bucket curl was starting to get stiff. No idea where to start on this.

With that much dust and dirt, I would look for the cleanest wet spot.

You could go to NAPA and get some of that florescent dye and put in the tractor hyd, and then work the hyd system. The dye will ooze out with the hyd fluid, and will fluoresce and using a black light will appear as greenish yellow.

do you have to change the fluid after you add the uv dye
does any buddy know of alternative filters for HH670-37710 and HH660-36060

The dye does not hurt AC compressor pumps so I think you can leave it in the system.

You may a more of a pin hole leak to be getting a misting like that from the one photo I opened. 3000 PSI is a lot of pressure to contain.

I agree a good pressure washer to clean it up then start looking of the leak. I guess I have been lucky in a way because a 5-10 gallon on the ground is not hard to find the source.

That one was due to a $2 blown O-ring.
