GENERAL
The air induction system is essential for providing clean air to the engine.
Dust and dirt, even in small amounts, can cause
engine failure.
The M109A6 air induction system consists of two air cleaners located in the crew compartment, engine
mounted turbocharger and blower, and ducting and hoses.
Between the air cleaners and turbocharger, the system is
under vacuum.
From the turbocharger to the engine, the system is under pressure.
Leaking components can be repaired
using tape, fiberglass, liquid metal, hose clamps, rags, or other similar materials.
Repairs to the turbocharger and blower
will usually require repair parts and standards maintenance procedure.
