Release the service brake pedal.
Depress the travel speed pedal fully in the FORWARD position.
Start Electronic Technician
Select the Machine ECM and then elect “OK”.
Select “Diagnostics” from the main menu.
Select “Diagnostic Tests”.
Select “Override Parameters”.
Select “Travel Pilot Solenoid Current Override” and set the current to 0.3 amp.Increase Travel Pilot Solenoid Current until transmission speed is equal to the specification in 1.Check the margin pressure on the pressure gauges with the travel pedal fully depressed.Note: Margin pressure is the difference between main pump pressure tap (1) and load sensing signal pressure tap (2).
Override the hydraulic modulation solenoid to 0.28 amp to set hydraulic modulation "Medium".
Check the margin pressure on the pressure gauges with the travel pedal fully depressed.
Override the hydraulic modulation solenoid to 0.38 amp to set hydraulic modulation "Low".
Check the margin pressure on the pressure gauges with the travel pedal fully depressed.
If margin pressure is not within the specification, perform the following "Adjustment Procedure" procedure to adjust the load sensing spool.Adjustment Procedure
Illustration 12 g06009594
Remove the cap and loosen the locknut on the adjustment screw for load sensing valve (3).
Turn the adjustment screw clockwise on load sensing valve (3) to increase the margin pressure. Turn the adjustment screw counterclockwise on load sensing valve (3) to decrease the margin pressure.Note: Turn the load sensing screw by a 1/8 turn to change the margin pressure by approximately 200 kPa (29 psi).Note: Always make the final pressure adjustments on the pressure rise.
Verify that the margin pressure is within specifications.Note: Refer to Table 1 for the correct pressure.
Tighten the locknut.
Install the cap.Note: If the cap was damaged during removal, replace the cap with a new orange cap.
