I have a Case 550 Long Track Crawler Dozer. It is the original model of the 550 manufactured from 1989 to 1991. They changed to the 550E starting in 1992 but I am not sure if the 550E had the same track specs.
The track and drive sprockets looks in fairly good shape and works great on flat ground but when I work on a faily steep sidehill the drive sprocket teeth start to climb up on the side of the rail (chain) until the track tightens up so much that it jams. I have to reverse a little to let the sprocket teeth settle back in the rail and then I can go forward again.
I want to measure the undercarriage wear to see if that is contributing to the problem but I cant seem to find the specs any where for the Case 550. Need to know what the new measurements are and what are the acceptable wear limits at say 50%, 75% or 100% wear. Looking for all the wear dimensions including rail (chain) pitch, rail height from bottom to underside of track pad, Rail bushing diameter, top idler roller diameter, bottom track roller diameter, drive sprocket diameter over teeth.
Not sure if these dimensions are in the service manual - I dont have one for this machine. Appreciate if anyone has this info for a Case 550 dozer and could let me know.
