10 INTRODUCTION Removal of transmission noise shields. Noise Shielding and Insulation Devices Maintenance Ensure sound shielding and insulating devices are intact. Inspect components for damage. Primary system components requiring noise related inspection include the hood, engine compartment insulating materials (including hood insulation, bulkhead insulation, doghouse insulation, etc.) splash shields, cab skirts, fender shields, and body panels. Inspect all related fasteners, brackets, and clamps for damage and tightness. Regulatory Compliance Acts that constitute tampering with the Noise Shielding and Insulation Devices:
Removing or rendering inoperative the engine and/or transmission noise deadening panels, shields or insulating materials. Removing or rendering inoperative any vehicle body mounted sound insulation components and/or shields (cab or fender shields, skirts, wheel housing splash shields, etc.). Cooling System Maintenance Visually inspect cooling system components for damage, and/or misalignment. Primary system components requiring noise related inspection include fan blades, fan clutch, fan shroud, fan ring, and recirculation shields. Check fan blades, fan ring, fan shroud, belt tensioner and recirculation shields for any damage. Verify that fan blades clear the fan ring.
Inspect all related fasteners, brackets, and clamps for damage and tightness. Confirm operation of temperature modulated fan clutch. Regulatory Compliance Acts that constitute tampering with the Cooling System: Removing or rendering inoperative cooling system components (such as the temperature modulated fan clutch, fan shroud, fan ring, recirculation shields, etc.). Exhaust System WARNING DO NOT work near the fan with the engine running or the ignition in the ON position. The engine fan can engage at any time without warning. Anyone near the fan when it turns on could be seriously injured.
