Noise Control System, Operator Inspection and Maintenance Requirements

A Noise Control System Maintenance Log located this This log should used document all Noise Control System related whether the maintenance results from a specific noise control system a deficiency identified during another general maintenance additional log space needed, further entries may added a separate sheet paper . Store these additions with the main log preserve a comprehensive record. recommended that copies all noise emissions related maintenance invoices retained.

The following Noise Control System inspection and maintenance instructions contain suggested maintenance intervals. These intervals may need adjustment order best accommodate the specific vehicle usage. The following instructions only concern Noise Emissions related items and not address modify any general vehicle maintenance requirements.

The following elements make the Noise Control System:

• Noise Shielding and Insulation Devices

• Cooling System

• Exhaust System/DPF System

• Air Intake/Air Induction System

• Engine EGR and Fuel Systems

• Selective Catalytic Reduction (SCR)

T ampering with Noise Control System

Federal law prohibits the following acts the causing thereof:

(1) The removal rendering inoperative any person, other than for purposes maintenance, repair , replacement, any device element design incorporated into any new vehicle for the purpose noise control prior its sale delivery the ultimate purchaser while use;

(2) the use the vehicle after such device element design has been removed rendered inoperative any person.

Among the acts that constitute tampering are the acts listed below:

• Removal, rendering inoperative, any exhaust components, including muf flers, heavy double - wall exhaust tubing, flexible tubing exhaust pipe clamping.

• rendering the temperature - modulated cooling fan

• Removal the cooling fan shroud.

• rendering the air cleaner air intake - line silencer

• Removal the sound deadening material from the hood cab tunnel.

• rendering the engine speed governor allow engine speed exceed the manufacturers

• Removal splash shields located inside the wheel housings.

Removal insulated rocker arm

Removal 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 rendering inoperative the engine and/or transmission noise deadening panels, shields insulating materials.

Removing rendering inoperative the cab - tunnel hood noise insulating

Removing rendering inoperative any vehicle body mounted sound insulation components and/or shields (cab fender shields, skirts, wheel housing splash shields, etc.).

Cooling System W ARNING

NOT work near the fan with the engine running the ignition the The engine fan can engage any time without Anyone near the fan when turns could seriously

Maintenance

V isually inspect cooling system components for damage, and/or misalignment.

Primary system components requiring noise related inspection include fan fan fan fan and recirculation Check fan fan fan belt tensioner and recirculation shields for any V erify that fan blades clear the fan Inspect all related and clamps for damage and Confirm operation temperature modulated fan

Regulatory Compliance

Acts that constitute tampering with the Cooling System:

Removing rendering inoperative cooling system components (such the temperature modulated fan fan fan recirculation

Exhaust System W ARNING

Hot engine! A void all movable parts hot engine exhaust gases, and/or A hot and/or fluids can cause

Maintenance

Make sure the exhaust system intact. Inspect for damage, misalignment and/or leakage. Primary system components requiring noise related inspection include exhaust manifold, turbochar ger , and all exhaust system (rigid and flexible) piping. Closely check the system for exhaust leaks. Special attention should given all welds, seams, gaskets, support points, clamps, couplings and connections.

Inspect all exhaust system and clamps for damage and
