clamp at the top of the reservoir and remove the lid. Place the drain bucket
under the reservoir and loosen one of the bottom fittings to drain the reser-
voir. Drain only enough fluid from the reservoir to expose bottom filter, then
tighten fitting. Remove the wing nut, filter spring and filter washer. Remove
the three drop in filters and install the new ones. Install the filter washer and
filter spring. Tighten the wing nut until wing nut reaches end of threaded rod.
It is recommended to install new hydraulic fluid. Old fluid may contaminate
the hydraulic system. Fill the reservoir with approximately three to four gal-
lons to the full mark. Install top and band clamp. Run engine to purge any
trapped air. Check fluid level after fifteen minutes of operation. Total system
capacity is approximately 44 quarts. Holiday Rambler filter number:
07010886. Nelson filter number: 84101B.
*One micron is one millionth of one meter.
The M-100 series Sheppard steering gear requires no maintenance. Power
steering is provided by using hydraulic pressure to assist rotating the output
shaft of the steering gear. Located at the end of the input shaft of the steering
gear is poppet valve and worm drive. The poppet valve directs the hydraulic
fluid pressure to a type of spool. There are worm drive threads in the center
of the spool. When in the center position, pressurized hydraulic fluid bypass-
es the spool. When a turn is made the poppet valve shifts to one direction or
the other, directing the hydraulic pressure to one side of the spool depending
on turning direction. The hydraulic fluid is then cooled before returning to
the reservoir. Inspect for signs of leakage when performing fluid level
checks. Changing the hydraulic filter at regular intervals will help ensure
trouble free operation.
The air filter minder is a precision overflow restriction gauge designed
to take the guesswork out of air cleaner replacement. The air filter minder
is located in the engine rear compartment. Its operation is simple and virtu-
ally foolproof. As dirt captured by filter cartridge slowly builds up the sys-
tem pressure drop increases and is indicated by the filter minder on an
easy to read scale. The indicator locks up at the point of maximum restric-
tion so readings can be taken with or without the engine running. When
the desired change-out point is reached, the air filter should be replaced
and the service indicator is easily reset by pushing the button at the bottom
of the minder.
