The operators and maintenance section contains detailed instructions, service information and technical data
which the operator will need in order to properly operate the 270-9 Auger and to perform the various
maintenance services that are required for keeping the equipment in good working condition at all times.
Included herein are complete descriptions of each operating control and step-by-step instructions on how to start,
operate and stop the equipment, and recommended operator's maintenance procedures.
The maintenance procedures and service instructions in this manual are included as recommendations only and
are based on normal equipment working conditions. Changes should be initiated by the user in order to
compensate for other than normal conditions and to meet the working requirements of any specific job
ENGINE AND POWER TRAIN
Power from the engine is transmitted to a torque converter and shuttle transmission, and a 4-speed transmission
is used. The power is transferred through a heavy duty universal drive line into a right angle drive, final drive
and kelly bar.
HYDRAULIC SYSTEM (FIGURE 1-1)
Oil is furnished by a 54 gallon tank through a suction strainer, to a gear-type pump. The oil flow is controlled by
self-centering valves. Oil pressure is 1450 P.S.I. hot, adjustable at the valve bank. A regeneration system is
used on the feed ram only. The oil is filtered through a micronic-type filter in the return line at the tank. This
system is highly effective and will give long life with minimum maintenance, provided the system is kept clean.
FUNK MODEL 1213704N0 TRANSMISSION
The Revers-O-Matic Drive, Model 1213704N0 is a shuttle-type transmission consisting basically of two (2)
hydraulically actuated multiple disc clutches. When the front clutch is engaged, the output shaft rotates engine-
wise and auger clockwise rotation is obtained. The rear clutch is driven by an idler/countershaft gear train and its
rotation is opposite to that of the front clutch. Therefore, when the rear clutch is engaged, the output shaft
rotates anti-engine-wise and auger counterclockwise rotation is obtained.
