I have a late 90's Zetor with a front end loader. Recently the bucket won't stay in the position it should be. It's in the tilt portion as the lift part stays up. I took apart the hydraulic fitting as it was drifting down, and it stopped. Makes me think it's in the valve, but I wander if it could be in the coupler?

rebuild hydraulic cylinder

That is exactly what I did and works perfectly now.
Several people told me other things

split or worn o-ring

The thing that makes me think it's the valve is sometimes if I "bump" the joystick it will hold where it is?

split or worn o-ring

If I change the configuration of the hoses would that isolate the fittings? Put the curl cylinders into the lift and vice versa?

 

[nosqrls]

Probably piece of trash in valve then.

 

[Whoo]

I crossed the hoses and nothing went down? Would this indicate that is something with the fittings?

 

[nosqrls]

Sounds like valve is not returning completely to center, for what ever reason. trash, varnish buildup, carbon buildup.

 

[Rural Kanuck]

Exactly......! Check all screws holding assembly together are tight....

 

[nosqrls]

You need to take that valve apart and clean and inspect it.

I've never messed with something like this. Is it something anybody can do it should I take it to a shop?

 

[nosqrls]

if you can get a diagram of the valve it is easy. a spool a spring or 2 a ball bearing (detent) a couple of o-rings. Something like this.

 

[nosqrls]

just don't take relief valve apart. this one 11-15 no need to do so. Detent ball and spring are in back cap.

Thank you!
