So my front bucket wont hold tilted up. It slowly rotates back down. Probably 3-4 minutes duration from full up to full down. Any thoughts? Obviously the valve is leaking.

Thanks

More likely you've got some "tired" front curl cylinders. Happens over time and use. Not a super hard job to rebuild or terribly expensive to have them rebuilt.

Be sure all your loader connections are good on your hydraulic lines. I put my loader back on one time and had that issue, and it turned out to be my mistake of not getting the quick connects all the way connected on one line. Also, check for leaks in the hoses.

Also, verify that the hydraulics are lifting the bucket up and down correctly and with the same strength. If they are, then it is a good possibility that the cylinders are worn.

One other thing to look at is the orings in the valve body. if one of those gets messed up, but could have an issue.

How do you determine if the the cylinders are operating with the same strength? No leaks that I can see. It is a heavy 4in1 bucket, but that shouldn't make any difference.

Thanks

The loader on the 110 is not a removable unit from the tractor - no quick disconnects - except the 3rd SCV function that would operate the jaws on the 4n1 bucket.

Generally, the cylinders will begin to show signs of wear before the spool valve body. However, there's always exceptions...

Do the loader arms begin to drop pretty quickly as well? What happens if you raise the loader and shut the engine off?

To determine whether the cylinders are leaking I would curl the bucket up and rest it on a large block of wood or rock. Then disconnect the curl lines and plug them off. Next, raise the fel slightly without using the curl circuit and remove the block. Shut off the tractor and watch the bucket to see if it creeps back down, if it does then the cylinders are leaking by.

If the bucket holds its position with the plugs in place then it is the valve circuit.

Thanks for the responses,

The loader arms do not drop at all with the engine off. Sounds like it is the cylinders. I will try testing with the lines plugged.

Thanks

So, I tested the curl rams by plugging the the lines to and from the cylinders. Started the tractor to raise the FEL arms and fluid shot out of the hard lines that would connect to the curl rams and the bucke did not curl down when isolated. JD service suggested looking at the check valves. Where are they, Where is the spool valve. I have not had a chance to look at the service manual yet.

Thanks in advance

I was gonna say something about that... really need some threaded end caps on the lines. There's a whole bunch of pressure on those lines!

The loader spool valve is right below the joystick on the right hand side of the tractor along the inside of the tractor frame. Just follow the mechanical linkage from the joystick - there it be.

AKfish, Thanks

Seems odd that fluid would come out without actuating the valve. I'll look for the spool valve and try switching out the check valves and see what happens

Thanks
