This document gives instructions about the mainte- attenuation parts for damage or incorrect installation, nance of a sound suppression kit for an 830E-1AC fixing where necessary. If this does not lower the rear dump truck.
Operating Instructions - Section 30 2/13 OM3072 Page 30-2 Exhaust System General The exhaust system on a sound suppressed truck exits from the back of the machine. There are two exhaust pipes wrapped with heat blankets (1, Figure 30-1) that carry the exhaust to muffler (2), located in between the chassis rails.
OM3072 2/13 Operating Instructions - Section 30 Page 30-3 Attenuators General Attenuators are fitted in various places around the engine compartment to muffle the noise. A typical attenuator is made of up numerous perforated split- ters (2, Figure 30-2). Each splitter is filled with a spe- cial insulation pillow (3, Figure 30-3).
Operating Instructions - Section 30 2/13 OM3072 Page 30-4 Engine Side Panels NOTE: If a significant amount of damage or soiling of any of the parts has been observed, replacement General insulation pillows must be installed to ensure correct performance of the parts. Both sides of the engine bay have been enclosed with attenuator panels (8, Figure 30-4), and access doors (7) for maintenance personnel.

An attenuator (8) is also installed in the belly pan to allow hot air to exit the The engine belly pan (Figure 30-5) is fitted below the engine compartment.
OM3072 2/13 Operating Instructions - Section 30 Page 30-7 Maintenance Approximate weights Refer to the Sound Attenuation System Service sec- tion for inspection requirements. Always use a lifting device that can handle the load safely. Lifting lugs are fitted to the top of the attenuator housings (8).
Operating Instructions - Section 30 2/13 OM3072 Page 30-8 Radiator Silencer Periodically, the attenuators need to be disassem- bled for maintenance. Refer to Sound Attenuation General System Service for maintenance intervals. Follow the steps below to service the attenuators. Sound attenuators have been added to the front of the radiator.
