I have a 1996 850D Case Dozer that was recently serviced by a "certified technician." Problems with the dozer is it would go in reverse but it wouldn't pull. The "technician" has pulled the dozer apart and it still isn't fixed.. Any suggestions on what to check would be appreciated. Here's what has been done so far....he took the reverse clutch out, replaced the ring that holds the clutch pack. The clutch pack housing was busted. He replaced the housing. Now you can switch the dozer in reverse and it won't pull, then when you press the gas pedal it won't move into reverse. You can let off the gas and then press the pedal and then it will go, still seems very weak. It will go into forward and pull in forward when using the levers and turn in forward with no problem. The problem is isolated to reversing. My thoughts are the problems are in the valve body. Does anybody have any info on how to run a pressure test on this model dozer or any suggestions on what to try next?
