AIR CLEANER, DAMAGED

General Information:

The air cleaners must filter all incoming air to the engine.

The air cleaners should be bypassed only as a last resort since

damage will occur as the engine injects the dust and dirt in unfiltered air if the air cleaners, ducting, and hoses cannot be

repaired, this procedure will provide minimum air filtration.

Limitations:

Damage may occur to turbocharger, blower, and/or engine

Personnel/Time Required:

•

1 soldier

•

0.5 hour

Materials/Tools:

•

Clean cloth (wiping rag, shirt or blanket) (scavenge from available source)

•

Clamp (scavenge from available source)

Procedural Steps:

CAUTION

Repairs to the air induction system should always be done with materials that

do not block the air flow and are securely attached to prevent them from being

sucked into and causing failure of the turbocharger, blower, and engine.
