EXTERIOR BOOTS AND DUST SEALS

dust seal. These components prevent contamination from
entering the housing around the shaft. If deterioration is
noted, these components should be replaced. The cavities
between the boots and seals should be filled with special
high temperature grease.
IMPORTANT! PLEASE READ AND FOLLOW
THESE INSTRUCTIONS TO AVOID
PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following general
precautions should be observed at all times.
1. Park the vehicle on a level surface, apply the parking
brakes, and always block the wheels.
2. Stop the engine when working around the vehicle.
3. If the vehicle is equipped with air brakes, make certain
to drain the air pressure from all reservoirs before
beginning ANY work on the vehicle.
4. Following the vehicle manufacturer’s recommended
procedures, deactivate the electrical system in a manner
that removes all electrical power from the vehicle.
5. When working in the engine compartment the engine
should be shut off. Where circumstances require that
the engine be in operation, EXTREME CAUTION should
be used to prevent personal injury resulting from contact
with moving, rotating, leaking, heated, or electrically
charged components.
6. Never connect or disconnect a hose or line containing
pressure; it may whip. Never remove a component or
plug unless you are certain all system pressure has
been depleted.
7. Never exceed recommended pressures and always wear
safety glasses.
8. Do not attempt to install, remove, disassemble or
assemble a component until you have read and
thoroughly understand the recommended procedures.
Use only the proper tools and observe all precautions
pertaining to use of those tools.
9. Use only genuine Bendix replacement parts,
components, and kits. Replacement hardware, tubing,
hose, fittings, etc. should be of equivalent size, type,
and strength as original equipment and be designed
specifically for such applications and systems.
10. Components with stripped threads or damaged parts
should be replaced rather than repaired. Repairs requiring
machining or welding should not be attempted unless
specifically approved and stated by the vehicle or
component manufacturer.
11. Prior to returning the vehicle to service, make certain all
components and systems are restored to their proper
operating condition.
REMOVING THE POWER STEERING GEAR
1. Mark or identify the inlet and return lines at the valve
body ports.
2. Drain the system following the instructions presented
under “Preventive Maintenance”. Remove both inlet and
return lines.
3. Disconnect the steering column at the input shaft
following the vehicle manufacturer’s instructions.
4. Disconnect the pitman arm from the vehicle’s steering
linkage using the vehicle manfacturer’s instructions.
CAUTION: If it is necessary to remove the pitman arm
before the steering gear is removed from the vehicle,
DO NOT USE HEAT OR POUND ON THE PITMAN
ARM OR OUTPUT SHAFT as damage can result. Do
not attempt repairs to these components. They must be
replaced if damaged. Use a large gear puller to remove
the pitman arm such as ‘Snap-On’ puller #CG-283 or
Ford part number T64P-3590-F.
