PROBLEM

Show/hide table

The existing harness assemblies can become loose due to poor crimping of the plastic insulated connectors on certain 794 AC, 796 AC, and 798 AC Off-Highway Trucks. These connectors are susceptible to dust and moisture issues if they are not crimped properly.

Rework Procedure

Note: Ensure that all safety information, warnings, and instructions are read and understood before any operation or any maintenance procedures are performed. Refer to the Operation and Maintenance Manual "Safety Section".

Follow these step to replace the red splices on the various harnesses listed below.

Step 1: Cut the wires, ONE AT A TIME, such that the splices are removed. Cut them as close to the edge of the red splice as possible, to give enough length to add the pin/socket and fit the crimper into the service area.
