ReferenceSpecial Instruction, REHS1841, "General Welding Procedures"

The wiring harness for the longitudinal stability indicator needs to be rerouted on certain TH220B, TH330B, TH340B, TH350B, TH355B, TH360B, TH460B, TH560B, and TH580B Telehandlers. Damage may occur to the harness or connectors for the 242-1741 Position Sensor As on the rear axle.

Rework Procedure

1. Park the machine on level ground and engage the parking brake. Lower the boom until the coupler is at rest on the ground.

2. Inspect the harness, the connectors and the sensor for signs of damage. Damage to any of these components will possibly cause the unit to malfunction. If the longitudinal stability indicator is malfunctioning and damage is evident to any of these components, replace the components before continuing with this procedure.

7. Use the 3S-2093 Cable Strap (5) in order to attach the harness to the 7T-1099 Link (4). Refer to Illustration 5.

Note: Adjust the harness in order to avoid any trap points. Adjust the harness in order to allow full oscillation of the axle.

Note: If your machine is equipped with frame level, tilt the machine completely to the right. Check that the harness has enough slack. The harness must not tighten.
