Hydraulic Oil
The hydraulic oil tank (4) is mounted on the right side
of the machine on the flywheel side of engine.
Careful selection of hydraulic oil should be used to
achieve maximum life and performance from hydrau-
lic system components. The hydraulic reservoir is
filled at the factory with an AW - 68. It has an SUS
viscosity of 344.3 @ 100° F and 54.2 @ 210° F. A
reputable supplier, RAYCO, or your RAYCO dealer
can help you make the best selection of an alternate
hydraulic oil for your machine.
Any engine oil of proper viscosity that meets one of
these API service classifications may be used: CC,
CC/SF, CD, or CE. Any military specification of MIL-
L-2104 oils of proper viscosity can also be used.
At normal operating temperatures, optimum viscosity
ranges are from 80-180 SUS. Viscosity should never
fall below 60 SUS, and at the lowest expected start-
up temperature, should not exceed 10,000 SUS.
Industrial-type hydraulic oils of proper viscosity that
are certified by the oil supplier to be chemically stable,
and to have antiwear, antifoam, antirust, and antioxi-
dation additives for heavy duty uses, are acceptable.
