Hi,
I have a Ford New Holland 675E that has a stabilizer safety control valve on each of the backhoe stabilizers. I believe the valve is there to prevent the stabilizer from sagging if the hydraulic system has a failure away from the cylinder.
One of the stabilizers recently started sagging, and I think this block is the problem because it vibrates quite a bit in a way that the good stabilizer does not.
Specifically, when I put the stabilizer down it will lift the machine, but then as soon as I let off of the control lever the machine will settle back down on the wheels.
I know it could also be an issue with the seal inside the cylinder, but I wonder about that for a few reasons:
- This started happening suddenly, it's not like it used to gradually sink and now sinks quickly. Now the machine will settle back to the ground in a few seconds
- When I hold my hand on the lever it will stay in the air. I guess this means the flow could just be more than the leak though?
I attached a photo here of the valve block on the stabilizer cylinder. I tried googling for the part number but came up empty.
So my questions are:
1 - Does this sound like a good theory that this safety block is the problem?
2 - Is it serviceable in any way?
3 - What are these things called to find a new part?
First time posting but these forums have saved me in the past. Thanks for any help!
