Important Information
When tests and adjustments are made to the transmission or the torque converter, the parking brake must be OFF. To prevent movement of the machine and personal injury do the procedure that follows.
1. Lower the blade and ripper (if equipped) to the ground.2. Put blocks in front of and behind the tracks.3. Let only approved personnel on the machine and keep all other personnel off the machine and in clear view of the operator.4. When testing must be done in a closed area and whenever possible, activate the service brakes if the parking brake can not be used. All tests and adjustments must be made with the oil in the hydraulic control system at normal temperature of operation. Be sure the linkage adjustments are correct before tests are made.Power Train Hydraulic System Schematic

Pressure Differential Valve Test
With the engine stopped, move the transmission selector lever to any position except NEUTRAL. Engage the brakes and hold them. Start the engine and run it at HIGH IDLE. The direction clutch pressure (P2) must be 0.0 kPa (0.0 psi) and the speed clutch pressure (P1) must be 2897 105 kPa (415 15 psi). Move the selector lever to NEUTRAL and then to THIRD SPEED FORWARD or REVERSE. The direction clutch pressure (P2) must now be 380 55 kPa (55 8 psi) less than speed clutch pressure (P1).
