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. The 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 pres-
sure 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 in the engine compartment at regular intervals will help ensure trou-
ble-free operation.
