I believe heating/cooling shrinking that Bushing the same way would work!

Would that method work on the D2 track frame to pivot shaft bushings?

I Have not had any experience with the pivot shaft bushings Neil so I cant be sure about them.
All I know is that when I used this method on the roller caps the inside diameter of the cap returns to its original size. the bronze bush is the only thing that changes.
I think the Roller caps are Cast steel not Cast Iron, So I think it would be a similar exercise on the pivot Deal.

I did read the old caterpillar directions on welding the rails and did deviate from their directions a little. The recommended way was a perimeter weld and then across the rail to fill in. After advice from a friend that has welded tracks and my welder friend I welded the perimeter then welded length ways to fill in. I had 3 to 6 rails going at a time and would do 2 welds and move to the next rail. This keeps the heat down and everything stays warm so I'm confident this will work fine. After trying both methods the length ways seems to give a smoother finish
This is my 59th link


I'm going to start trying to get the bushing out of the caps with the heat and cool method. I still have to clean the caps so the bushing can be measured. I think a couple might be within spec. Seems like the rollers with good seals dont have that much wear, imagine that!
Got a track frame on the welding table.


Glad to have the track welding behind me

First parts going back together instead of coming apart. Throw out bearings removed and reinstalled

Good news is the 7B9968 seal is in fact a direct replacement for the d2 lower roller bellows seal

Looks really good Gary, you're going to love that new steering!

Already liking the new steering, seems ashame to cover them up

Almost done with one track frame. I was able to salvage all of the holes for bolting the rollers and the sheet metal. I cut the frame where the front idler runs back and forth and replace the section with the wear. Still have a few holes to weld up and spring mounts to put on. I cut the old spring mounts off my other frames but they're to wore out to use for anything except a pattern.

I had 6 arms for the idler to choose from, so I picked the best and welded them up.



One actually didn't need any welding
