Section VI. ACOUSTIC SUPPRESSION KIT
5-28. GENERAL
The acoustic suppression kit provides the ability to lower the noise level of the generator set to 70 dB(A) at 7
meters. It consists of panels, doors, and components that rover or replace original components of the
generator set. The generator set is operated and maintained in the same manner; however, access to
components and operation will change slightly due to configuration changes.
Remember that the overall weight and cube of the generator set will increase with the acoustic suppression
kit installed. (Refer to TM 9-8115-464-12, para 1-10.) Inspect the components of the acoustic suppression kit
upon delivery for bends, cracks, dents, missing components, or other damage.

WARNING
Do not use hoisting equipment with maximum capacity less than 5,000 pounds. Do not
allow generator set to swing while suspended. Do not allow personnel under generator
set or components of acoustic suppression kit when hoisted or lifted. Death or severe
injury may result.
CAUTION
Use a minimum bridle of 5 feet on the hoisting sling to avoid undue side pressure on
the lifting frame. Failure to observe this caution could result equipment damage.
NOTE
If generator set is trailer–mounted, generator set must be removed from trailer, and
rubber isolators supplied with kit placed between the generator set and trailer mounting
surface. When installing the generator set, attach anti-rotation clip, and attach the
mounting bolts. Bolts should be torqued to 5 ft- lb (6.80 Nm) and jam nuts installed.
(Jam nuts are common hardware items.) Once the acoustic suppression kit is installed,
gen set will require 1 inch ground clearance. Do not skid gen set with acoustic
suppression kit installed. Do not forklift unless both side panel skirts are in the raised
position. If generator set is trailer-mounted, the trailer brackets supplied with kit must
be installed. The brackets allow for the extended length when the acoustic suppression
kit is installed.
Refer to operator and unit maintenance manual, paragraph 4-135, and remove the following: battery
box doors, radiator grill, side doors, louver doors under control panel, control panel doors, and both
front and rear top covers.
