BEARING GP 1554242 - Caterpillar

Rotate the input shaft in a counterclockwise direction. Adjust the input rotation to 1400 10 rpm.
Maintain input speed, oil flow, and pressure for 5 minutes in order to purge the air from the system.Torque Converter Pressure And Leakage Test
Adjust Tooling (M) counterclockwise in order to remove restriction from inlet flow.
Adjust the output flow at the No. 2 flow meter to 132.5 9.5 L/min (35.00 2.50 US gpm).
Adjust Tooling (M) clockwise in order to increase supply pressure to 1516.8 34.4 kPa (220.00 5.00 psi).
Adjust the input rotation to 1400 10 rpm.
Record the torque converter inlet flow at the pressurized flow meter in Table 6.
Record the torque converter inlet pressure in Table 6.
Record the torque converter outlet relief pressure in Table 6.
To obtain the leakage, subtract the output flow from the input flow.
Record the calculation in Table 6.Lockup Clutch Test
Adjust Tooling (M) counterclockwise in order to remove restriction in the inlet flow.
Adjust the output flow to 132.5 9.5 kPa (35.00 2.50 psi).
Adjust Tooling (M) in order to increase supply pressure to 1516.8 34.4 L/min (220.00 5.00 US gpm).
Readjust the output flow to 132.5 9.5 L/min (35.00 2.50 US gpm).
Use Tooling (P) to engage the lockup clutch.
Record the lockup clutch pressure in Table 7.
Record the leakage of the lockup clutch in Table 7.
Use Tooling (P) to disengage the lockup clutch.
Stop the input rotation.
Stop the input flow.Contamination Control
Drain all oil from the torque converter.
Take an oil sample of the test bench oil supply. Oil contamination must be below ISO 16/13.
Record the results in Table 8.
Remove the torque converter from the test bench if the test bench oil supply is within specifications.Specifications
