Priority valve (3) makes sure oil pressure is first available for steering, braking and transmission control, and then for torque converter operation and lubrication of the steering clutches, brakes, and transmission. The priority valve group is mounted on the lower left side of the bevel gear case. Use pressure tap (K) for all priority valve pressure measurements. Use pressure tap (C) for all torque converter inlet relief valve pressure measurements.Priority Valve Adjustment
1. Adjust priority valve (3) by turning adjustment screw (26); One turn equals ... 135 kPa (20 psi)2. Lock adjustment screw (26) in place with locknut on the adjustment screw. Expected Result:* Parking Brake ON and RPM 700 30 ... 1100 kPa (160 psi) Max.* Parking Brake OFF and RPM 700 30 ... 2925 100 kpa (424 15 psi)* Parking Brake OFF and RPM 2245 30 ... 1100 kPa (160 psi) Max.Torque Converter Inlet Relief Valve Adjustment
1. Adjust torque converter inlet relief valve (4) by turning adjustment screw (25); One turn equals ... 40 kPa (6 psi).2. Lock adjustment screw (25) in place with locknut on the adjustment screw. Expected Result:* At an RPM of 2245 30 ... 790 70 kPa (115 10 psi)Main Relief Valve Adjustment

Main Relief Valve (12)
(12) Main relief valve. (27) Adjustment screw.Introduction
Main relief valve (12) controls the pressure in the power train oil system. The relief valve is located on the top of the transmission planetary group. Use pressure tap (E), located at the rear of the machine, to measure the pressure setting for main relief valve (12).Main Relief Valve Adjustment
1. Adjust main relief valve (12) by turning adjustment screw (27); One turn equals ... 235 kPa (34 psi).2. Lock adjustment screw (27) in place with locknut on adjustment screw (27).Expected Result:
* Pressure at 700 30 RPM ... 2925 100 kPa (424 15 psi)* Pressure at 2245 30 RPM ... 3100 150 kPa (450 22 psi)Power Train Oil Pump Bench Test Specifications
