The Lubricating System Part V

Through the and with the kind permission of International
Harvester Company, 401 North Michigan Ave., Chicago, Illinois
60611, we are printing a series of interesting information from the
book Internal Combustion Engines and Tractors.

Anyone having tractors will find these articles very valuable
and those who do not have tractors will find them interesting. This
is the fifth and last contribution in this series. This one is on
the International 15-30-a medium weight tractor that operates on
kerosene.

FOUR-CYLINDER MOTOR

The engine is of the four-cylinder type, set horizontally, so
that power is delivered direct to transmission through spur gears
without bevel gears. Completely enclosed. Dust-tight crankcase with
removable cover.

MIXER —

One mixer with four fuel needle valves and a single water needle
valve is used, which reduces adjustments to the minimum. This mixer
will handle any of the cheap fuels, such as kerosene, distillate
down to 39 degrees Baume, gas oil, solar oil, motor spirits,
gasoline or naphtha.

GOVERNOR –

A fly-ball throttling type governor controls amount of fuel
entering cylinders in proportion to the load.

IGNITION –

The ignition is jump spark, current being furnished by
high-grade gear driven magneto — no battery required.

LUBRICATION —

Motor is lubricated by automatic force feed oiler with twelve
feeds. Transmission is lubricated by an oil bath.

COOL1NG. —

The motor is water-cooled, circulation through cylinders, tank
and a vertical tube radiator being secured by a belt-driven rotary
pump.

TRANSMISSION –

Two speeds forward and one reverse, all controlled by a single
lever. Roller bearings. Gears run in oil. Double chain drive to
rear wheels. Chains tightly encased.

STEERING –

Automatic type.

Mechanical Lubricator

Fill with a good grade of heavy gas engine cylinder oil. Turn
the crank on the mechanical oiler 40 to 50 times when starting the
engine. The drain at rear of crankcase pan must be kept open at all
times to allow the used oil to pass off.
