u-frame 450b

[hoonboy]

The u-frame on my 450-b is scrubbing the on right side tracks especially when the blade is tilted to the left. It was apparently a problem long before I got it because shims had been welded on the u-frame and even on the hydraulic cylinder. I just assumed the u-frame was hopelessly warped. I've checked it for square and I can't detect a warp. Could the rear bushing be so worn as to account for this much misalignment? I have already replaced my frame rails,idler spacers and the front cross-bar and new bushings so I think it is running true.

Theres a good chance the pins and bushings at the back of the U-frame are shot. I have new replacements available if you need them. If you have any other questions feel free to contact me directly at [email protected] Good Luck. Steve
