801 lift arms

john in la · Dec 5, 2018

In the middle of moving 72 yards of dirt to extend a driveway and my left lift arm came off the ball where it mounts under the tractor.

Do I need to replace the entire arm?
Or can the just the ball be replaced?
If just the ball what keeps it from coming back out?

Some have repaired those. I'd rather replace the arm . . . or if you know a good welder you can likely buy an aftermarket end for the link, curt the old ball and socket off and weld the new one in its placde.

2 options:

1. Cut and weld new end on. They sell online, Steiner. There are other places.

2. Find another arm. Also sell new, but plenty of arms around it seems.

After the old ball wears to the point it comes out of the socket not much can be done.

You can replace the whole arm or you can buy just the end of the arm and cut the old end off and weld a new end on.
The ends are the ball and the socket and a stub of 2 3/4".

The weld on ends are 14.99 at TSC SKU # 26779199. I am not saying to buy them there just the first place I looked.

I don't think it would be advisable to try to reattach the arm over the old ball.

Your decision should be made after looking at the wear on the other end of the arm. I look at them as throw away wear items, but I don't weld either.

Another option, if you happen to have a lathe and a 600 ton hydraulic press handy...
Make a set of dies and press it back together.
Works good. Wink

My 5030 ford did the same thing. I took the arm off and welded around the outside of the ball. Welding small amounts at a time making sure not to let weld stick to the ball. It has held for 10 plus years now. Nathan

I?ve done the same thing that Mtf did, weld a bead or rim around the edge being careful not to weld the ball , easy to do, done it on several old tractors

Thanks guys.

I did like Mtf suggest to get the job done.
I see my local TSC has the ends in stock and considering tax and shipping they are only about $1 more than online so I am going to weld on new ends when I get caught up around here.
