  • Case 9010 excavator track adjuster

    The undercarriage on this machine is completely worn out. The rest of the machine is pretty much on its last legs so owner does not want to dump money into it. Just needs to get it out of where it is back to it's final resting place at the farm where it will just help process firewood. Chains are stretched to where the adjusters are maxed out and one of them blew out because of this. Track keeps falling off so he can't get it out of where it is very easy. Cheap solution, push the track adjuster out as far as I can to tighten the track and weld it in place. You definitely want something behind it to keep it from pushing back in and not just rely on the outer welds in front. Used my short porta-power to push roller out as far as I could to tighten the track. Shimmed the roller bearing slides to kind of center it up and down as they were really worn out. Welded them up. Next I cut a slot in each side frame and slid a 3/4" plate in behind the bearing housing to keep it from collapsing. This should keep the track tight until the end of it's life. You can see how far the bearings are out of the slides, they should be back in a few inches. Needs a link removed but that requires extra work and money.

    Here is the plate welded in and the final pic with track tightened as best I could. Second pic you can see the plate behind the bearing housing bolt inside the frame. I did this on each side of the roller, slid it on and then welded it all around on the outside. This will keep it from being able to slide back in and the track loosening. As long as he is careful this should last a long time. After I was done I thought I probably did not have to weld the bearing housings to the shims. Just the shims to the frame and the 3/4" blocks would have been enough. All done, packed up, paid and 15 minutes away my phone rings. Owner says I did a great job but he went about 75 feet and the other side blew out. I turned around and went back to do the same thing on the other side.
