3-156. AIR CLEANER - MAINTENANCE INSTRUCTIONS.
a. The air cleaner is designed to remove foreign matter from the air, pass the required volume of air for
proper combustion and maintain their efficiency for a reasonable period of time before requiring service.
b. The importance of keeping dirt and grit-laden air out of an engine cannot be over-emphasized since
clean air is so essential to satisfactory engine operation and long engine life. The air cleaner must be able to
remove fine materials such as dust as well as coarse materials such as lint from the air.
c. The fins on the element give high speed rotation to the intake air, which separates a large portion of
the dust from the air by centrifugal action. The plastic fins, the element and the gasket make up a single
replaceable element assembly.
d. The dust is swept through a space in the side of the baffle and collects in the lower portion of the
body. The dust remaining in the precleaned air is removed by the element.
e. The air cleaner has a replaceable impregnated paper filter element that can be cleaned.
