I have to rework the pivot shaft on my CAT22, 2F5209. The inner bearings (1B1462/3) for the angle braces are shot and need to be re-bushed, thus the track frames flop around. The outer bearings (V-224) need to be re-bushed. They have seriously worn the pivot shaft outer end. See photos: DSC_0093 (2).jpgDSC_0094 (2).jpgDSC_0095 (2).jpg
I was able to remove the left mounting bracket (V-266), but have had no luck loosening the right bracket. Not sure I need to. I also have had no luck removing the left spacer (V-267) so that I remove the inner bearings, and don't see any way I can get a purchase on it to knock it off. Any suggestions? I am thinking I will just cut the spacer off and make a new one out of tubing.
What bothers me the most is how much the outer bearing area is worn, as can be seen in the photos. Also, the threads on the outer end are stripped. What do you think I should do? I was thinking I could try finding a machine shop that can turn down the bearing area and then undersize the bushings in the outer bearing area. Likewise, the threads could be chased or turned down slightly and then use an undersized nut.
I guess the alternative would be to try to find a pivot shaft that is in good condition and does not require as much work.
Any thoughts or suggestions are much appreciated. Ray
