The E'Bar on near most all D6 high drives can usualy be found to have some issue to the pin mounts (3) or the bearings, this is 1 area that CAT seem to struggle with even after loads of up-dates to the beam and all pin locations, the grease or oil that you stuff into them often fails to repay your efforts, the centre pin location to the main frame is out of sight and often out of mind for most service men and drivers, the bushings in the track frames often rattle loose and add to the pain, the beam end bearings need to slide on the pins to counter the distance change as the frames move through their full range of movement, even this bearing-pin sliding hardly handles the arch range of the frames, near every LGP D6 tractor in the U.K. over about 3 years old will have some need for repair work within this area, the centre pin location has had a few repair update sheets printed on this location, plus the beam has had loads of updates, if I need a job I only have to look at an equalizer beam in a D6H/R, its not 1 of CAT's better days work, I would recomend its greased or oiled 3 times a day then it might last a few years??
