Elongated Holes

[woodlandfarms]

So a few weeks ago I posted about how my steering cylinders where flopping around... I wanted to show you the elongated holes. This is something that my 1850 suffers from in a variety of places. I don't think that this is the best design, but I get why they do it. I will order new ears, or makes some up next time, but for the moment I welded on grade 8 washers and replaced the bolt and that will keep me through the summer.

that shouldn't happen if there is enough lubrication.. it probably ran dry.. the short bearing surface contributed to that too, is that 1/2" that wore?.

It looks to me somebody already welded a washer on top of an elongated hole and that matches the grove cut into the bolt. Just a note, be careful welding on the hyd reservoir when full of oil.

So it appears.
Not enough contact/bearing surface. Needs to be a sleeve or tube.
Grooves in the bolt confirm that.

Drilling oversize and using a matching oversized bolt/pin would be a preferred fix.

Yikes!

It seems like somebody, you?, has already done that quickie fix, but you are putting a great deal,of the hydraulic force on a small area, with the washer taking the brunt of the force. You can see all the wear on the bolt.

New eyes are the way to go. Welding them on should be a quick fix, depending on your tools for cutting metal.

Drilling an eccentric hole like that is tough on the drill and bit, but it can be done. However, it isn't going to leave you with much metal, and I would worry about the strength of the eye if you go over size.

All the best,

Or drill oversized then put in a bushing to reduce the hole down to the size of the original bolt.

I have used shaft couplings to make bushings. Sometimes had to add gussets each side to reinforce where cutting out for the OD of the bushing doesn't leave much meat. Tack a flat plate on the back side of the elongated hole and use a hole saw to cut out for the bushing.

I am more wondering why the original elongated. I seem to be the only one in the group with this issue.

ANYONE ELSE WITH WEAR LIKE THIS???? Is it in all joints in the machine or just one? How many hours? Did you do the proper 8hr lube? What task was the machine used for?

I lube my machine religiously but even so, after sitting for a few weeks when I started using it on a job, it had a creek. Not knowing if it could be that center pivot (Z bar) on the loader, I spoke to Terry. He said the ball joints need more lube. Now I spray them up after every hard workout, it is easy enough. Far quicker cleaner easier cheaper faster, did I mention easier then using a grease gun!!!!

Souunds similar to my 425. I thought for sure the steering valve was going out with the horrible noises I'd hear when turning. Terry said lube the steering ram ends. I told him I did. He said do it again, but really soak them down. OK sure buddy. So I soaked the heck out of them and guess what? The sound went away. :ashamed: Even though I was lubing them often, apparently I wasn't putting enough lube on them. So now I spray them all down as I walk around the machine, then make a second pass. That seems to give it time to soak in.

What do you use to lube them with?

 

[m5040]

Super Lube 31110 Aerosol

Super lube.

 

[cqaigy2]

Super Lube and spray lithium grease. Sometime old gasoline with dissolved lithium grease, i use a small chip brush and slather it on.

My bet is that the prior owner didn't lubricate the eyes, they then elongated out, the prior owner then tacked on the washer to hide the elongation and reduce the rattle, and you bought into a previously worn eye that was resting on 3/32" of mild steel, which wore down quickly. Are all the elongated holes ones that don't have grease zerks?

I don't think it was your doing, despite all the wild driving on 45 degree slopes (kidding!). My bet is that if you put new eyes on and lube them regularly that you won't ever have this issue again.

FWIW: I use super lube as well.

All the best,

Peter

The reason the holes elongated was first was not lubing the joints and second not keeping the bolts tight. The fix is weld up the hole and bore it....... jim

 

[m5040]

This brings up a common thing that I often contemplate. Is it better to have the bolt tight enough that it bends in the ears and clamps the center ball, which then would cause the ball to rotate in the socket when in operation? Or do you want the ball to rotate on the bolt and randomly rotate in the socket too?

 

[MossRoad]

Looking at mine, i can't see a reason you'd want the ball to rotate around the bolt since the eye rotates on all planes around the ball.

 

[MossRoad]

Probably a good question for Terry.

 

[cqaigy2]

yes good call for Terry, but i'd think the balls are just to allow enough adjustment, to make the connection and that you'd still want the joint to be were most of the movement to take place.
