NEW D11R/N POST TURN TRACK SEALS
Caterpillar now offers new ?Post Turn? Track Seals (PTS) available for all D11R/N track. These new seals have a smaller diameter than the original factory seals. This smaller diameter seal should be used whenever a bushing with a maximum of 50% bushing end grooving (as measured with the 4C-8613 bushing end grooving gage) is being returned to service, such as during a bushing turn or re-seal. The smaller diameter seal will contact a new, unworn bushing surface providing better seal reliability after service.
