![]() ![]() You need the 120 PSI or neither clutch pack will make up. The hydraulics to operate the reverser are internal via a small pump on the spyder shaft. In Reverse, the straight thru shaft is the one idling. The counter shaft is always rotating, but does nothing power flow wise until the Forward clutch is disengaged and the Reverse clutch is made up (again by hydraulic pressure). Power flow is thru the Spider shaft (input) of the reverser and straight thru the center when the Forward clutch is made up by hydraulic pressure. I would really love to speak on the phone with someone who has knowledge of the power flow. When the reverser is out of the tractor and the transmission is in gear should I be able to turn the imput shaft of the transmission and the tracks not move? Or if something is broken in the final drive. Im trying to figure out where the pressure drop is It need 100 to 120 psi to engage the clutches and move ?ĭoes the steering clutches also need 100 to 120 psi for the tractor to move. The reverser has about 30 psi of pressure. We reassemble the machine and it still wont move. The counter shaft was twisted in 2 at the front bearing. We disassembled tractor and removed the reverser. He told me he had been adding reverser fluid about every 10 to 12 hrs. ![]() It was working fine and He was grading some gravel and heard a load pop and the loader stopped moving in it tracks. ![]() My son in-law has 1980 350 c crawler that wont move no forward or reverse. ![]()
