| Air Bleeding Single Steering System |
|
Note: If this is a replacement steering gear, please follow the poppett/plunger
adjustment procedure for automatic adjusting steering gears prior to bleeding system.
Caution: For Steps 1 and 2 do not turn steering wheel or air may be induced into
system.
Step1 : Fill reservoir to nearly full. Crank the engine for 10 seconds without allowing
it to start. If it does start, shut off immediately. Check and refill the reservoir. Repeat
process at least three times, checking the reservoir each time.
Caution: Do not allow fluid to drop significantly or run out of reservoir as this may
induce air into system.
Step2 : Start engine and let it idle for two minutes. Do not steer. Shut off engine and
check the reservoir fluid level. Refill if necessary.
Step3 : Start the engine again. Steer the vehicle from full left to full right several
times. Add fluid, as necessary to full line on dipstick.
Note: The above procedure should remove all air from steering system. If gear is
mounted in an inverted position and is equipped with a manual bleed screw,
commonly found with TRW/Ross steering gears, please continue to step 4.
Step4 : Follow the above procedure. Leave engine idling. With the steering gear in
centered position, loosen the bleed screw about one turn (5/16 inch socket required for
TRW/Ross, 1/8” allen wrench for Sheppard ). This allows the air and aerated fluid to “bleed out” around bleed screw until only clear (non aerated) fluid is present. Close
bleed screw and check and fill reservoir if necessary. Torque manual bleed screw to
27-33 inch pounds.
Caution: Do not turn steering wheel with manual bleed screw loosened.
| Air Bleeding Dual Steering System |
|
Bleeding the dual steering gear system is necessary whenever the system has been
repaired. The bleeding procedure is the same no matter the gear sizes used.
 |
Raise the vehicle up until front wheels have cleared surface. |
|
Inspect fluid level in reservoir to ensure it is full. Continue filling after starting
engine and during the bleed process to maintain correct fluid level.
Note: Do not allow reservoir to empty during this procedure as it can cause pump
damage or further aeration. |
|
Remove drag links from both master and slave gears pitman arm following the
procedure in vehicles service manual. |
|
Start engine and allow it to idle. |
|
Turn steering wheel to full left and hold until slave gear moves its full travel. Then
turn full right and hold until slave gear moves its full travel. Repeat this three or
more times. |
|
Connect drag link to the master gear. Torque attaching nut according to vehicle
service manual.
Note: Do not back off nut while finding cotter pin hole.
Note: Always use new cotter pins, retainers or fasteners. |
|
Install new cotter pin through ball stud nut and lock in place.
Note: Not installing a new cotter pin in ball stud could result in loss of steering
control. |
|
With the master gear drag link connected, turn the steering wheel too full left turn
and hold until slave gear pitman arm reaches full travel. Then turn the steering
wheel to full right turn and hold until slave gear pitman reaches full travel. Repeat
this three or more times. |
|
Connect the drag link to the slave gear, turn steering wheel until pitman arm lines
up with drag link. (Do not move the pitman arm by hand as air may get into
system.) Torque attaching nut according to vehicle service manual. |
|
Install new cotter pin through ball stud nut and lock in place. |
|
Turn full left and full right several more times. |
|
Inspect fluid level. |
Keep your system clean
We recommend when replacing a power steering pump or gear:
* Inspect all hoses and fittings * Fluid is flushed and replaced *Filter is changed |
