Diesel engine exhaust contains products of combustion which may causepersonal injury.

Always start and operate the engine in a well ventilated area, and, if inan enclosed area, vent the exhaust to the outside.

Personal injury or death can result from sudden machine movement.

Sudden movement of the machine can cause injury to persons on ornear the machine.

To prevent injury or death, make sure that the area around themachine is clear of personnel and obstructions before operating themachine.

Personal injury can result from rotating and moving parts.

Moving fan blades and moving parts will throw or cut any object or toolthat falls or is pushed into them.

Make sure no one is working on, underneath or close to an engine thatis running. Make sure the area is free of personnel.



Personal injury can result from hydraulic oil pressure and hot oil.

Hydraulic oil pressure can remain in the hydraulic system after theengine has been stopped. Serious injury can be caused if this pressure isnot released before any service is done on the hydraulic system.

Make sure all of the attachments have been lowered, and the oil is coolbefore removing any components or lines. Remove the oil filler cap onlywhen the engine is stopped, and the filler cap is cool enough to touchwith your bare hand.

NOTICECare must be taken to ensure that fluids are contained duringperformance of inspection, maintenance, testing, adjusting and repairof the machine. Be prepared to collect the fluid with suitable containersbefore opening any compartment or disassembling any componentcontaining fluids.

Refer to Special Publication, NENG2500, "Caterpillar Tools and ShopProducts Guide", for tools and supplies suitable to collect and containfluids in Caterpillar machines.

Dispose of all fluids according to local regulations and mandates.

6. Remove the locking pin and raise support bar (6) in order to secure the engine hood. Install the locking pinin order to secure the support bar.




7. Unlock latch (7) and open right engine door (8) .

8. Use the following steps in order to disable the brake release system with the manual brake release valves.

Illustration 5 g03335767Located by the Manual Brake Release Pump

a. Loosen the set screw on needle valve (9). Rotate needle valve (9) clockwise in order to fully close thevalve. Tighten the set screw.

Illustration 6 g03335768Located by the Propel Pump



b. Loosen the set screw on needle valve (10). Rotate needle valve (10) clockwise in order to fully closethe valve. Tighten the set screw.

9. Use a suitable lifting device in order to lift the machine off the ground. The weight of the machine isapproximately 27000 kg (5925 lb). Place jack stands under the machine.


10. Apply Tool (P) to NPT sides of Tool (A). Connect one Tool (A) to each side of Tool (B).

11. Assemble Tool (C) and Tool (D). Connect one Tool (D) to each Tool (A) on Tool (B) .

12. Connect Tool (E) to each end of one Tool (F). Connect Tool (E) from tool assembly to Tool (C) on inlet sideof the flowmeter.

13. Connect Tool (E) and Tool (G) to other Tool (F). Connect Tool (G) on tool assembly to Tool (C) on theoutlet side of the flowmeter.


14. Disconnect case drain hose assembly (11) from the propel motor on the right side of the machine.

15. Connect the hose assembly on inlet side of Tool (B) to the case drain port on the right propel motor.

16. Connect the hose assembly on outlet side of Tool (B) to hose assembly (11) .




17. Connect Tool (S) and Tool (T) to Tool (R). Connect Tool (S) diagnostic connector (12). Connect Tool (T) toUSB port on Tool (P) .

18. Move engine start switch (3) to the START position. Release the switch when the engine starts.

19. Launch the Plus+1TM program on the computer in order to allow the machine to go into high idle.

Note: First time users need to perform the tasks in the Communication and Connections Wizard. Thiswizard allows the Windows® operating system to recognize the USB device. Follow the on screeninstructions.




20. Click on "Configurations" button (13) .

21. Go to "Park Brake Test Mode" (14), click dropdown list (15) .


22. Select "Throttle Active" (16) from the dropdown list.

Note: The "Throttle Active" option allows propel lever (1) to control engine rpm without engaging thepropel system.

23. Move propel lever (1) to the FORWARD position.

24. Operate the engine at high idle. Engine speed should be 2300 ± 50 rpm. Monitor the hydraulic oiltemperature with Tool (U). Operate the machine until the oil temperature reaches 43 ± 5.6° C (110 ± 10° F).

25. Move parking brake switch (2) to the OFF position.

26. Read the flow on the flow meter. The flow should be 3.8 L/min (1 US gpm).

27. Move propel lever (1) to the NEUTRAL position in order to operate the engine at low idle. Engine speedshould be 1000 ± 25 rpm.




28. Go to "Park Brake Test Mode" (14), click dropdown list (15) .

29. Select "Normal" (18) from the dropdown list. Selecting the "Normal" option returns the machine controls tostandard operation.

30. Click on "Exit" button (17) in order to exit the Plus+1TM program.

31. Move propel lever (1) out of the NEUTRAL position (one quarter to one half full travel) .

32. Record the flow on the flow meter as "right motor case flow". If the flow is less than 15 L/min (4 US gpm),go to Step 34. If the flow is greater than 15 L/min (4 US gpm), repair or replace the right propel motor.

Note: The flushing valve directs 9.5 ± 1.9 L/min (2.5 ± 0.5 US gpm) into the motor case. In order todetermine actual motor leakage, subtract the flushing valve flow from the total flow.

33. Move propel lever (1) to the NEUTRAL position in order to operate the engine at low idle. Engine speedshould be 1000 ± 25 rpm.



36. Remove the tooling, and reconnect case drain line (11) to the propel motor on the right side of the machine.
