    If you go from 1/2" slop to 1/8" slop, it will feel like a new machine. Personally, on a low use machine, plain steel bushings last just fine with grease every now and then.

    Depending on how bad the holes are split tension bushings could be a good option. They're spring steel so will last longer, don't generally require grease and aren't real expensive. They also don't need a perfect bore. If part of the bore was worn too much, build it up with weld and grind it closer with a die grinder or cone stone.

    I can recommend tension bushings as a fix. A machine I purchased new had composite bushes which lasted 300hrs. They were replaced under warranty with torsion bushes and they were still good when the machine was sold at 6000hrs. Due to the dusty environment the worked they weren't ever greased and I did keep an eye on them in case they wore through.

    Ok, what are tension bushings? I look on the net and see lotso Cat and Deere. Are these that rare? Is the rest of the machine that queer? I got no problem buying but can't find any?

    There was a grader blade bolted on under the edge. It's worn out. It appears there is another piece welded on underneath. It has about 3/4 inch left to wear it and the weld out. At the edges it is more worn. I was going to do some replacement but thought I might give it a go with some hard rod I got for a job long time ago.
    I am going to get some close pics, I was thinking of adding a hard bead to the edge and building out the corners a layer on the underside. Is the center strong enuf as it is to keep from busticating it? Right now it's all straight. I'm gonna keep the prying with the center to a minimum. 20210118_124045.jpg 20210118_124022.jpg 20210118_124009.jpg

    Maybe back the camera up slightly, it looks blurry from being to close

    Nice work though

    Yes, after I take it realize it was blurred. I normally am fussy and try to get as much in a single pic as I can. I have bushings in and simply welded all the way around and left room to put a seal in. I ruined my hole shooter till I got out a larger drill to run a hole saw. I do this again going to get a carbide vs a common bi metal. We used a weed sprayer and water to drill.
