Add fluid to the reservoir as needed.
When clean power steering fluid flows
from the hose, remove the plug from the
reservoir and reconnect the steering gear-
to-reservoir hose to the reservoir. Re-
move the jack stands and lower the ve-
hicle.
4.4 Install a new filter into the reservoir. In-
stall the filter spring and the filter top
plate.
4.5 Clean the reservoir cover and O-ring seal.
Inspect the O-ring and the cover for
cracks, deformities, or damage. Replace
the O-ring seal or cover as needed.
4.6 Install the reservoir cover and the clamp.
Tighten the clamp 25 lbf·in (280 N·cm).
5. Using ATF fluid that meets Dexron III or TES-389
specifications, fill the power steering reservoir
with approved power steering fluid to the FULL
COLD mark.
6. Start the engine and operate it at idle. Turn the
steering wheel to full lock left and right to adjust
the fluid level and remove any existing air from
the power steering pump and gear. Recheck the
fluid level. Add fluid as needed. The system is
properly bled when the steering pump does not
labor when turning the wheel.
7. Check for leaks in the power steering system,
and repair as needed. Top off the power steering
fluid level as needed.
46–03 Power Steering Fluid
Level Inspection
1. Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
tires.
2. With the engine cool, use a shop towel or clean
rag to clean the area around the power steering
reservoir fill cap. See
Fig. 1 or Fig. 2 . Twist the
cap counterclockwise to remove it. Check the
cold power steering fluid level. The level should
be between ADD COLD and FULL COLD with
the engine off.
3. Start the engine and run it at idle until it reaches
operating temperature.
On Century Class Conventionals, remove the
dipstick and check that power steering fluid is
between ADD HOT and FULL HOT. If the fluid
level is low, add enough fluid to bring the level
up to the FULL HOT mark on the dipstick.
On Argosy COEs, check that power steering fluid
is between the ADD HOT and FULL HOT lines
on the transparent reservoir. If necessary, add
enough ATF fluid that meets Dexron III or TES-
389 specifications to bring the level up to the
FULL HOT mark on the dipstick.
46–04 Power Steering Gear
Lubrication
Sheppard Steering Gears
Sheppard power steering gears manufactured with-
out grease fittings are maintenance-free. If the power
steering gear has no grease fitting, it requires no pe-
riodic lubrication.
Sheppard power steering gears with grease fittings
must be lubricated periodically.
1. Wipe off any debris from the bearing cap grease
fitting. See
Fig. 3 .
2. Using a hand-type grease gun, apply multipur-
pose chassis grease until grease starts coming
out of the bearing cap dirt-and-water seal.
