what do i call the piece outside rail that my idler pin holder slide on?its a 850b dozer.feel stupid askin,but im not getting no were tryin to find part not knowing what to call it.the whatchamacallit search had no results.
Take a picture with your thingamyjig & post it so we'll all have a better idea.
Track frame, perhaps?
If its welded to the frame its just a piece of flat bar for a shim and wear. If its the square piece bolted to idler with a big hole in it and four bolts i call it an idler plate. If it's between that plate and frame its another shim or wear bar.
