AIR INTAKE SYSTEM

TM 9-2350-238-20-1

The spade is a welded steel structure used to prevent sliding when winching heavy loads. It is

raised and lowered by two double-acting hydraulic cylinders.

AIR INTAKE SYSTEM

Engine air is filtered by a two-stage process that takes outside air through the battery access door

grilles into two intake air cleaners, and then through two filter elements.

Intake air cleaners. The intake air cleaners are a system of tubes and deflector vanes that

give a swirling motion to the incoming air. This swirling action forces large dust particles against the

walls of the tubes. The dust falls into the dust chamber. Centrifugal fans exhaust the dust to the

outside air through ports on the left side of the vehicle.

Intake filter elements. The intake air then passes through fabric filters that collect the

remaining dust. The clean air is routed through engine intake air ducts and the turbocharger to the

engine blower and combustion chambers.
