CONE 0012995 - Caterpillar

Test Procedure
Note: Tests and adjustments must be made with the power train oil at the normal temperature of operation. Make sure that control linkages are correctly adjusted before making any adjustments.
Move the machine to a smooth horizontal location.
Lower all of the implements. Engage the parking brake. Turn the engine OFF.

The pressure taps for the transmission control valve are located under an access plate on the top of the transmission case. The transmission is located under the floorplate of the operator station. (F) Pressure tap for the direction clutches (G) Pressure tap for the speed clutches
Remove plug (F) and plug (G) from the transmission control valve. Install tooling (B) in each hole. Attach tooling (A) to tooling (B) .
Start the engine. Warm the power train oil to operating temperature.
Disengage the parking brake. Make sure that the transmission selection lever is in the NEUTRAL position. Make sure that the steering control levers are in the NEUTRAL position. Operate the engine at HIGH IDLE.
Check the pressure at tooling (A) that is connected to pressure tap (G). The pressure at tooling (A) should be 2600 75 kPa (375 10 psi). Check the pressure at tooling (A) that is connected to pressure tap (F). The pressure at tooling (A) should be 380 55 kPa (55 8 psi) lower than the reading of pressure tap (G) .
Disengage the parking brake. Make sure that the transmission selection lever is in the NEUTRAL position. Make sure that the steering control levers are in the NEUTRAL position. Operate the engine at LOW IDLE.
Check the pressure at tooling (A) that is connected to pressure tap (G). The pressure at tooling (A) should be 2275 kPa (330 psi) minimum. Check the pressure at tooling (A) that is connected to pressure tap (F). The pressure at tooling (A) should be 380 55 kPa (55 8 psi) lower than the reading of pressure tap (G) .
The pressure relief valve of the sequence relief valve must be tested if the pressure reading of pressure tap (G) is out of tolerance. Refer to Testing and Adjusting, "Sequence Relief Valve - Test and Adjust" that is in this manual for the testing and adjusting procedure.
The primary setting of the direction clutch must be tested if the pressure reading of pressure tap (F) is out of tolerance. Refer to "Primary Setting of the Direction Clutch" for the testing and adjusting procedure.
When the pressure setting is correct, remove the test equipment. Prepare the machine for service.Primary Setting of the Direction Clutch
Move the machine to a smooth horizontal location.
Lower all of the implements. Engage the parking brake. Turn the engine OFF.
