reaction plates, except for the high gear
clutch that uses eight of each plate.
The power from the engine is transmitted to
the Shift-O-Matic through a torque
converter. The use of the torque converter
has two distinct advantages, one is the
converter is essentially a fluid drive, their
being no direct mechanical connection
through it. This feature creates a very
smooth and shock free drive eliminating
engine stalling and lugging. A second
advantage is that the converter transmits
the engine power directly at almost engine
speed, and there is no torque multiplication.
The net result is an action like a
transmission, with infinitely variable and
automatic speed ratios. The need for
shifting gears, although present, is greatly
reduced.
1.3.6 Lubrication System
An oil pump draws oil through a strainer in
the oil pan and circulates the oil through the
engine. Before entering the engine, all the
oil from the pump passes through the oil fil-
ter. Surplus oil drains back into the pan. En-
gine oil pressure is maintained by a
spring-loaded pressure-relief valve in the oil
pump.
The screw-on oil filter has an internal relief
valve to bypass the filter if the element be-
comes clogged.
Engine oil flows through the oil cooler cavity
to be cooled by coolant which flows through
plates inside the oil cooler.
1.3.7 Fuel System
The lift pump draws fuel from the fuel tank
through a pre-filter, and delivers it to the
water separator and fuel filter. The fuel exits
the fuel filter and flows to the four injectors.
1.3.8 Fuel Capacity
20.7 gallon; 78.3 liters.
1.3.9 Air Cleaner
The air cleaner is a dry element type and is
located on the right front fender. It prevents
dirt and other foreign materials from enter-
ing the engine.
1.3.10 Exhaust System
The exhaust system consists of an exhaust
manifold, catalytic converter, exhaust pipe,
muffler and tail pipe. The exhaust manifold
has large radius curves which permit ex-
haust gases to leave the cylinders with a
minimum of back pressure and power loss.
All parts of the exhaust system are well
supported with clamps and hangers.
1.3.11 Corrosion Proofing
All frame and body surfaces are shot
blasted, primed and painted with weather
resistant paint. Standard bolts are SAE
grade 5, zinc-phosphate coated to resist
corrosion.
1.3.12 Tires
Front and rear tires are 10.00 x 20 16 ply
rated, load range H.
1.3.13 Electrical System
1000 CCA battery and 95 amp alternator
with internal regulator. Has starter lock out
switch (prevents started and ring gear dam-
age when engine is running). Tractor starts
only in neutral. All circuits protected with cir-
cuit breakers.
