I have my 1958 420c undercarriage apart. Does anyone know if the idler bracket is steel or iron? JD part# m1824t & m1823t. The pin bore is worn and I would like to weld and rebore back to size. Had anyone welded these in the past???

I am measuring 19 1/8" x 1.73" on both front idlers and 7.15" on th...

One rollers i.d. bearing was so bad it ate the seals and half of the pin. There is noticable wear on the end castings. The other pins and end castings look ...

Thanks Jim, knowing the material is very helpful. Now I am wondering what the stock size the O.D. of the rollers and idlers should be? How much wear is tolerated? The right side rollers look o.k.. I will have to mic. them for wear and decide if I want to build them up as well. I was also considering...

I just purchased a 5-roller 420c. The undercarriage needs some work. The previous owner had to remove a track link to get the tensioners to work. On the left side the first four rollers have the R.H. flange wore off and the front idler bushing is completly wore out. It is so bad the track does not s...
