Ford 841 lift arms stuck in raised position.

[Bob in Tennessee]

I just removed a backhoe attachment from my 841 and I cannot get the lift arms to drop. The arms have been in the raised position for years and I am not sure where to start. I must assume its a mechanical issue due to the rigidness of arms but before I proceed, your advice is invaluable. I have read that I cannot remove my lift cover with the arms in the raised position. Any suggestions how to proceed without damaging anything?
Thanks
Bob

I suspect that the rockshaft might be rusted in place. Try a good penetrating oil like Kroil or PB Blast around the shaft on both sides of the tractor, where the shaft disappears inside the top cover. You may need to do it several times a day for several days before it will begin to move.

Thanks Sean! I will give it a go.

stuck unload valve, and rust ring in lift cyl also can cause this.

Remove the arms from the rockshaft to insure that they aren't rusted to the housing and to enable getting penetrating oil in there.

My 10 cents is on mechanically stuck as I suspect hyd would have leaked off by now.

The arms move easily so I'm thinking mechanical. I will try to remove lift cover this weekend.
thanks

The negative to removal with the arms in the up position is the oil bath that you get which shouldn't happen in your case.

Probably just a bit of misunderstood terminology adding to my misunderstanding here, but if the arms are stuck in the fully raised position and will not lower, then how do they "move easily"?

What I meant to say is the arms move off the shaft easily, but the shaft is stuck in the up position.

I'll remove the lift cover out in the yard just in case of the oilbath! Thanks for the heads up!
