PROBLEM

The differential locks are failing at low hours on certain 621H, 621K, 623H, and 623K Wheel Tractor-Scrapers. Debris generated during clutch engagement can be trapped inside the piston and damage the piston and seals causing the hydraulic oil to mix with the differential oil.

ACTION REQUIRED

For all groups replace the existing four tooth differential lock jaws with updated eight tooth differential lock jaws.

For Groups 2 and 4, update the differential lock system to the new high pressure differential lock system. The installation of high pressure differential lock requires the three updates listed below:

1. A new differential lock mechanism (housing and piston) with a reduced volume.

2. New lines routing that will go from the fan/brake/differential lock manifold through the front of the differential case via a bulkhead and directly to the differential lock mechanism.

3. New fan/brake/differential lock manifold that has increased pressure and flow capability.

Refer to M0075476, Special Instruction, "Procedure to Improve the Differential Lock on Certain 620H and 620K Wheel Tractor-Scrapers", for the procedure to install high pressure differential lock system and the eight tooth differential lock jaws for machines that have not updated to the high pressure differential lock system.

Refer to M0123057, Special Instruction, "Procedure to Update the Differential Lock Jaws on Certain 620H and 620K Wheel Tractor-Scrapers", for the procedure to install the eight tooth differential lock jaws for machines that have already updated to the high pressure differential lock system.

For Group 3, 4, 5, and 6 machines, remove the wheel speed sensor group from the machine. The removal of the wheel speed sensor group will prevent debris generation and will prevent debris from damaging the differential lock piston seals. Removal of the wheel speed sensor group will require new transmission/chassis software.

Software to be installed:
597-9738 Transmission/Chassis Software

Note: Removal of the wheel speed sensor groups will cause the following changes:
- Differential Lock Engagement Protection (DLEP), Tire Spin Reduction (TSR), and Advanced Tire Spin Reduction (ATSR) will be disabled.
- Changing the Advanced Tire Spin Reduction Installation Status configuration in Cat ET to "Installed" will not enable this feature.
- The Tire Spin Reduction button backlight on the keypad will be disabled. LED indicators will be disabled. The Tire Spin Reduction button LED indicator blink only when the Help Feature button is pushed.
- Total Differential Lock Engagement Protection Activation Count does not increment in Cat ET.
- Left Front Wheel Speed, Right Front Wheel Speed, Left Front Axle Speed, and Right Front Axle Speed parameters will show * * * in display.
