KIT-MARKER 3327777 - Caterpillar

Start Service Mode and maintain power shift pressure at 2550 50 kPa (370 7.25 psi).
Depress the following three switches on the operator monitor panel at the same time: fine control mode switch (D), user mode switch (E) and travel alarm cancel switch (G). Hold all three switches down for at least three seconds.
The controller display (A) will be "00 00 00".
Input the service code "0E 32 3A". To increase the flashing character, push the boom priority mode switch (B). To decrease the flashing character, push the swing priority mode switch (C). To move the flashing character to the right, push the fine control mode switch (D). To move the flashing character to the left, push the user mode switch (E) .
Once the service code is entered into the controller display (A), depress the following three switches on the operator monitor panel at the same time: fine control mode switch (D), user mode switch (E) and travel alarm cancel switch (G). Hold all three switches down for at least three seconds.
The controller display (A) will change to "10 -- 1".Note: If more than ten seconds pass between pushing the switches, the controller display (1) will revert to the operation mode.
On the operator monitor panel, enter a fixed power shift pressure of 2550 kPa (370 psi) on the controller display (A). Adjust controller display (A) in order to attain a power shift pressure of 2550 kPa (370 psi) on the pressure gauge at pressure tap (1) .
Move the flashing character to the far left. Increase the "1" to a "6".
Move the flashing character to the right and increase the "0" to a "6".
The last four characters on the controller display (A) will begin flashing. These characters represent the power shift pressure (kPa). Adjust the last four characters to "2550". To increase the power shift pressure 10 kPa (1.5 psi), push the boom priority mode switch (B). To decrease the power shift pressure 10 kPa (1.5 psi), push the swing priority mode switch (C). To increase the power shift pressure 200 kPa (29 psi), push the boom priority mode switch (B) and power mode switch (F) at the same time. To decrease the power shift pressure 200 kPa (29 psi), push the swing priority mode switch (C) and power mode switch (F) at the same time.Note: Always use the pressure gauge that is connected to pressure tap (1) to monitor the actual power shift pressure.Note: Refer to Service Manual, "Engine and Pump Electronic Control System" for additional information on Service Mode.Note: To prevent a change in power shift pressure during line relief valve adjustment, do not turn the engine OFF.
Maintain either one of the main pump pressures at 4900 kPa (700 psi) and keep the other pump without load.
