Power Train Oil Filters
"Transmission Front Oil Filter Plugged" will be displayed on the Advisor module if the front transmission oil filter becomes plugged. "Transmission Rear Oil Filter Plugged" will be displayed on the Advisor module if the rear transmission oil filter becomes plugged.
(B) Pressure tap for the power train oil pump. (The pressure tap is located on the left side of the machine.)
Install the correct hose assembly from 1U-5482 Pressure Adapter Group on the following pressure taps: (B), (D), and (G). See Illustration 4 and Illustration 5 for reference. Attach the opposite end of the hose assembly to the 0 to 3400 kPa (0 to 580 psi) pressure gauge in the 1U-5481 Pressure Gauge Group.
Engage the parking brake. Shift the STIC transmission direction control switch to the NEUTRAL position. Shift the transmission to first speed. Start the engine and operate the engine at low idle.
Depress and hold down the right service brake pedal. Release the parking brake. Watch the pressure gauges. Shift the STIC transmission direction control switch from the NEUTRAL position to the FORWARD position. Increase the engine speed to high idle. Make sure that the transmission oil is at normal operating temperature. The needle on the pressure gauge for the Number 2 clutch should rise. The needle on the pressure gauge for the Number 5 clutch should rise. The pressure readings must be within the values that are found in Table 3.With the transmission in the FORWARD position, shift through the remaining forward speeds and return to the FIRST SPEED position. The pressure reading for each clutch that is energized must be within the values that are found in Table 3. This checks the pressure of all the speed clutches.
Perform Step 3 for all reverse speeds. The same pressure levels should be noted in all reverse speeds.Test for the Lubrication Oil Pressure
Use the following procedure to check the pressure of the transmission lubrication oil.
Install the correct hose assembly from 1U-5482 Pressure Adapter Group on pressure tap (J). See Illustration 4 for reference. Attach the opposite end of the hose assembly to the 0 to 400 kPa (0 to 58 psi) pressure gauge in the 1U-5481 Pressure Gauge Group.
Start the engine and operate the engine at high idle. Observe the pressure gauge. With the oil at normal operating temperature, the lubrication oil pressure must be within values that are found in Table 3.Transmission Pressures
