TM 9-6115-624-BD
(a) Dismount a blower motor (such as dust exhausters), connect to power source with long leads, and blow
dirt from air cleaner.
(b) Disconnect exhaust hoses from all but one blower. Connect hoses together using tape to gain sufficient
length to reach outside. Start engine and blower, blow dirt deposits from filters.
(c) Use air from a disabled wheeled vehicle's tires. Remove valve stem and connect rubber hose to valve
and proceed to blow out filters.
(d) Use brake air tank from wheeled vehicle by connecting rubber hose or place filter directly under air flow
from valve.
(e) Other options: Use vacuum cleaner. Gently tap filter against hard surface.
Record the BDAR action taken. When the mission is completed, as soon as practicable, repair the generator using
standard maintenance procedures.
4-9.
Air Cleaner, Damaged/Leaking. The air cleaner must filter all incoming air for the engine. Damage
or leaks that cause the air cleaner to be ineffective must be repaired. Any leaks in the filter housing or duct
work can be taped over or covered by a rag that will filter any air coming through the leak. Sealing the leak
is preferred. Only as a last resort should the air cleaner be bypassed or eliminated. Damage will occur as
the engine ingests the dirt and dust in unfiltered air. If the only option is to eliminate the air filter, this
procedure will allow a minimum amount of air filtration.
a. Limitations.
Possible degraded output
b. Personnel/time required.
1 soldier/.50 hours
c.
Materials/tools.
Duct or electrical tape (item 22, appx c)
Section cut from blanket or shirt
d. Procedural Steps.
(1) Disconnect the air hose at the attachment to the engine (figure 4-2).
(2) Cover the air inlet with clean rag (use a shirt or blanket if no rags are available). Clean the rag whenever it
gets dirty.
(3) Anchor the cloth tightly to the air intake with a hose clamp or wire, otherwise the strong vacuum will suck the
rag into the engine.
(4) Other options: Bypass or eliminate air cleaner.
Record the BDAR action taken. When the mission is completed, as soon as practicable, repair the generator using
standard maintenance procedures.
4-10. Intake Manifold or Other Castings or Containers, Damaged . Intake manifolds are difficult to repair.
Autobody fillers, epoxys or gasket sealers can seal cracks. Holes will require welding because of irregular surfaces.
Tape will provide a temporary seal on unpressurized air intake portions but has minimal value for pressurized systems
without metal or wire re-enforcement. Epoxy kits will make an almost permanent repair, if time is available for curing.
Follow the individual kit directions.
