Bx 25 backhoe will not stay up

[Q tip]

When I run my backhoe it always falls down I had the cylinder rebuilt and it still does it I can bump the left lever it stops going Down
I can use it but it’s a pain in the neck it won’t stay put in one place on it’s own this is at full rpm and low rpm
Any ideas
Thanks guys

Sounds like you need to get into and do some work on the valve body.
First before getting in too deep, check the detent / centering spring on the bottom of the spool for that section that is falling, they are all the same so compare it to another section.
Also check the upper linkage for any binding, broken, or misaligned parts.

Was able to remove the cap on the bottom of the valve that was causing my problem the spring was cocked was able to free it up now the back hoe does not creep was a quick fix I got lucky
