BH92 Backhoe Stabilizer Arm Droop

[John E. Law]

I have noticed that the right side stabilizer arm for the BH92 backhoe drops down to the ground overnight after use. Is this normal or is this telling me there is a leak somewhere?

Not normal, kinda nice to have an automatic parking brake though
#1 cause.... probably the ram seal(s) is shot
#2 cause.... spool valve sticking 'down' ??

#3 possibility…. Control valve for that stabilizer has greater than average leakage through it. Wonder if you could swap hoses between the two control valves and see what happens?

Obviously a leak somewhere - the question is where. I am inclined to think the cylinder since the other one stays up.

Easy to test. After you park it put a strap on the stabilizer to keep it up and disconnect the rod end hose and cap/plug the port on the cylinder. Then take the strap off and check if in the morning. If it does not stay up the cylinder is leaking.

Don't worry about it, just chain them up together, just remember the chain.

I keep the stabilizers strapped together anytime the tractor is in storage.

Well, I have the same droopy stabilizer leg on my Bh77.
Valve stack was replaced under warranty.
Couple weeks later stabilizer started drooping in about 10 minutes.
Bad problem is that it wont support the tractor very long when digging.
I have to keep adjusting that stabilizer when digging.

If it leaks down when extended the problem is almost surely the valve
