PROBLEM
Without heat shielding, the wiring harnesses may be exposed to excessive temperatures from an exhaust leak that may cause harness damage on certain G3520C landfill engines. Heat shields are needed to protect the detonation and thermocouple wiring harnesses. If exhaust leak has occurred, perform REBE3547 if applicable.

Rework Procedure
1) Remove the exhaust manifold shielding and insulation to allow better access to thermocouple and detonation wiring harnesses.
2) Move existing ladder clips to the lower threaded holes on cam covers. The ladder clips should be oriented on top of the bolt as shown in Image 1.1.1. The wiring harnesses should be installed on the bottom of the ladder clip using cable ties. Be sure to leave adequate length on the thermocouple wire to get around the shield.
Image1.1.1
3) On the back of the engine, near the ITSM(if equipped) the wiring harness should go under the ITSM mounting bracket. Cable ties should be used accordingly to secure the harnesses. This can be seen in Image 1.2.1

4) Make sure water lines clamp bracket are aligned as shown in Image1.3.1. There should be a clip added to each bolt for this water line
