I broke my loader....

Bellville · Jun 6, 2005

While doing some loader work yesterday the curl function on my loader stopped working. It is the 419 loader on a 790. The lift function still works, and if you apply downward pressure while backing up it will curl up and if you lift it, it falls down, in other words it is not frozen or locked up in any way.

There is no hydro fluid leaking out anywhere and if you actuate the curl function I can still hear the hydro pump, makes the same sound as when you are fully extended in either direction.

Any ideas as to what I might have broken would be appreciated.

Thanks

Jack,

Double check the couplers first; sometimes they can look like they are attached but aren't.

You didn't say so I'm going to mention it even tho I'm sure you did check the oil level. Other than that it sounds like a valve problem. I wonder if you can swap the hoses so you can use your lift to curl and vice versa just to check the valve?

i could be wrong,, im not a tractor mechanic but it sounds like a problem in your main selector valve assembly. the one your joy stick is stuck in. maybe there is a rebuild kit for it.

Check all of your couplers first.

This post See if this link helps, I recently posted about the same problem.

Well after checking that link, I see you were in that post, so maybe you have checked all that my next step would have been to use a gauge and find the last point on that circuit with pressure. Good Luck !

Thanks for all the replies. Unfortunately my tractor lives at my property and I live elsewhere, so any further checking will have to wait to this weekend.

Best thing is the tractor is still under warranty, and as I have a few other things to have looked at, a trip to the local dealer is in my near future.

Thanks again.

Got back to the tractor this weekend, checked all the couplings twice, does not seem to be the problem. Loaded it up and headed to the dealer.

Got bad news when I got there, implements only have a one year warranty, ouch...

Hopefully it won't be to bad, I will post a follow up when I get the damage.
