Noise Control System, Operator Inspection and Maintenance
Requirements
A Noise Control System Maintenance Log is located in “Noise Control
Log” on page 27. This log should be used to document all Noise
Control System-related maintenance, whether the maintenance results
from a specific noise control system inspection, or a deficiency
identified during another general maintenance event.
If additional log space is needed, further entries may be added on a
separate sheet of paper. Store these additions with the main log to
preserve a comprehensive record. It is recommended that copies of all
noise emissions-related maintenance invoices be retained.
The following Noise Control System inspection and maintenance
instructions contain suggested maintenance intervals. These intervals
may need adjustment in order to best accommodate the specific
vehicle usage. The following instructions only concern Noise
Emissions-related items and do not address or modify any general
vehicle maintenance requirements.
The following elements make up the Noise Control System:
앫 Noise Shielding and Insulation Devices
앫 Cooling System
앫 Exhaust System/DPF System
앫 Air Intake/Air Induction System
앫 Engine Control, EGR and Fuel Systems
