Weak FEL loader LA352

[53gravely]

I have a 2005 B7610HSD w/ LA352 FEL (500 hrs) that has gotten weak on the lift arms in both directions.

First, over the last couple months, the float function got hoaky….will pop out of the detent very easily (not sure this is related). Recently, the bucket won’t lift more that 200lbs above 18” off the ground, nor does it have the downforce to lift the front wheels off the ground.
The curl/dump function seems fine….i can lift the front wheels off the ground with the dump function.

With the timing of the float issue and the problem with just the lift arm function, I’m guessing it’s the up/down circuit in the control valve. Am I on the right track?

How hard are these to rebuild without a shop full of tools for hydraulics?

Thanks!

Check the position of your three point lever. If it's in the full up position it can cause the hydraulics to go into bypass mode robbing power from any other hydraulic accessories. If that's your problem the solution is to move the three point lever a bit off of full up. If that does it your rock shaft needs adjusted.

There is nothing to rebuild inside the valve but the centering spring and detent assembly under the cap or cover can fill with crud and not allow the spool to move properly.

Also double check linkage from joystick to the valve spool to confirm it is working properly.
