3.6.1 On the 3 kW, 5 kW, or 10 kW, ASKs may be removed from the generators and the generators will
function normally. For 5 & 10 kW generators new replacement kits may still be available from the
supply system for purchase and installation if the owning unit wants to retain the reduced acoustic
signature provided by the kits.
3.6.2 On the 15 kW and 30 kW generators the exterior generator panels were removed to install the
ASKs. The ASK panels reduce the generators acoustic signature and protect generator set components
from environment elements. If 15 and 30 kW ASK panels/doors have failed, replacement ASK
panels/doors must be installed or the complete kit must be removed and original generator panels/doors
must be installed. Failure to enclose the 15 & 30 kW generators sets will lead to weather damage of
internal generator set components and potential overheating of the main alternator, engine, and other
generator components, as the exterior panels and doors duct cooling air through the generator
components.
3.6.3 Mil-Std generators have a short remaining life and repairs should proportionate to the expected life
of the generators. The preferred order of repair options is as follows:
1) On the 3 through 30 kW ASKs, panels can be repaired by welding or riveting new sheet metal
over rust holes. Recommend that RTV be used to seal riveted panel patches. Fiberglass may also be used.
Pound out dents when possible. Weld angle iron onto panels to repair edges. Since the ASKs are not
mandatory, repairs to the acoustic insulation are not required, unless the unit wishes to maintain the
acoustic suppression capability. There should be standard hardware available for most of the screws,
washers and nuts. Patches or new material should be CARC painted after installation.
2) On the 5 & 10 kW generator sets, if the ASKs cannot be repaired or the damage is major,
complete kits may be ordered from the supply system. The 5 kW kit is NSN 6115-01-273-7377. The 10
kW kit is NSN 6115-01-273-7376.
3) If three or more panels require replacement, remove the ASK from the 3, 5 or 10 kW
Generator sets unless reduced acoustic signature is critical to the Soldier mission.
4) On all ASKs, if two or less panels require replacement, new panels can be locally fabricated.
Technical drawings for the ASK components can be obtained from CECOM. Panels may also be
available from commercial sources. Contact CECOM Generator Branch RESET Team (DSN 992-1313,
generatorreset@mail1.monmouth.army.mil) for additional information.
5) On the 15 & 30 kW ASKs, if two or more panels require replacement the total generator set
may be uneconomical to repair. Calculate total repair cost for repairing generator set and replacing ASK
components and compare cost with MEL. If cost is less than MEL, repair generator set.
Reports also indicate that there is an interference fit between the ASK on the MEP-701 and the engine
conversion kit that replaces the original engine with a Yanmar engine. If the engine kit must be installed
on a MEP-701, the ASK can be removed and the generator converted into a MEP-016B, or the ASK can
be modified to fit around the engine. Modifications should ensure that exhaust from the engine is ported
outside the ASK, and there is sufficient clearance around the engine to avoid engine to ASK contact and
allow for cooling airflow. The ASK can be cut and modified as required providing the key points from
above are followed: Use common sense, CARC paint finished repairs, and maintain the air seal of panels
and air flow to preserve generator set cooling.
