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 bypasses 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 virtually foolproof.
As dirt captured by filter cartridge slowly builds up the
system 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 restriction 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.
To replace air cleaner remove three screws and
cover from air cleaner body. Remove air cleaner car-
tridge and discard. Install new air cleaner cartridge and
secure with cover and three screws.
WARNING: Do not start the engine with
the air cleaner removed and do not
remove it while the engine is running.
