Backhoe Boom Drift

[tho2nd]

Wallenstein GX90 (new last year, so maybe 30 hours on it)

I'm experiencing a rather rapid boom drift. Any time I switch to loader work, I have to pin the boom, otherwise it drops to the ground in a manner of minutes.

It's done this since day one at which time the dealer said it was normal. I didn't like it, it doesn't seem right, but since I'm no heavy equipment expert, I took their word for it.

Here it is a year later and I still don't like it and I still don't think it's right for the boom to drift that quickly.

Any thoughts, suggestions?

Thanks!!

You have some 'junk' in the seat of that valve in that circuit that is allowing the fluid to leak past the seat. Only takes a very tiny amount of anything (like a metal filing) to cause that and no, not normal. Least not a 'fast' leak (pressure drop).

Thank you....I didn't think so either
