SECTION 2. AIR CLEANING SYSTEM
1.GENERAL DESCRIPTION
Unfiltered air contains many particles harmful to the engine such as dust ,sand,or other foreign matter.
When such foreign matter have entered in to the engine,They have mixed into the lubricant and promote
wear of lubrication parts in addition to damaging the piston cylinders.To eliminate these harmful
particles,an air cleaner has been installed.The air cleaner Which is installed on the T series tractor is a
dry,cyclone type and is constructed as shown in the figure.
Under the influence of suction generated by the engine,unfiltered air flows through air inlet tube and is
forced into a high-speed centrifugal motion.By this circulating action most of the dust and dirt particles
are separated from the air and collected in the dust unloading valve(4).The remaining dust is removed as
the air flows through the paper element(2) before being drawn into the engine.
