=====''Nissan 240sx S13 Power Steering Rack and Pinon: lubrication, adjustments and more''=====
Certain 240SX models are equipped with a High Capacity Actively Controlled [[SuspensionRearS13 Suspension]] (HICAS) 4-wheel steering system. This system uses a dual power steering pump, rear power cylinder, HICAS solenoid, fail-safe valve, control unit and various sensors to control rear wheel angle. Rear wheel angle is based on vehicle speed and steering angle.

==''PINION ROTATING TORQUE & RACK SLIDING FORCE''==
Rack sliding force can be checked with steering gear installed in vehicle, with tie rods and pinion shaft disconnected. Perform pinion rotating torque adjustment with steering gear assembly removed from vehicle.
**Pinion Rotating Torque**
1. Remove steering gear from vehicle. Install steering gear in soft-jawed vise. Drain fluid from steering gear.
2. Remove lock nut and adjusting screw. [[http://www.garage411.com/images/Nissan/S13/steering/steering2.gif see figure]]. Apply locking sealant to threads and install adjusting screw. Lightly tighten adjusting screw lock nut. Tighten adjusting screw to 43-52 INCH lbs. (4.9-5.9 N.m). Loosen adjusting screw, then retighten to 1.74 INCH lbs. (.20 N.m).
3. Install Torque Adapter (J-26364 ) and INCH-lb. torque wrench on pinion shaft.
{{image url="http://www.garage411.com/images/Nissan/S13/steering/steering2.gif" title="text" alt="text"}}
Move rack over its entire stroke several times. Measure pinion rotating torque within range of 180 degrees from neutral position. Stop gear at point of maximum torque. Remove adapter and torque wrench. Loosen adjusting screw, and then tighten to 43 INCH lbs. (4.9 N.m).
4. Loosen adjusting screw 70-110 degrees, then tighten lock nut. Ensure adjusting screw does not turn when lock nut is tightened.
5. Install Torque Adapter (J-26364 ) and an INCH-lb. torque wrench on pinion shaft. See Fig. 2 . Measure turning torque required to rotate pinion. If pinion rotating torque is not as specified, repeat step 2). If after readjustment, pinion rotating torque is still not as specified, replace steering gear.
**PINION ROTATING TORQUE SPECIFICATIONS (Measure within 100 degrees of neutral position)**
~-Nissan S13 240sx: 16 inch pounds (1.9 N.m.)
**Rack Sliding Force*
1. Position wheels in straight-ahead position. Raise and support vehicle. Remove front wheels. Remove cotter pins and nuts from tie rod ends. Disconnect tie rod ends from steering knuckles. Remove lower steering column joint from pinion shaft. Start engine, and run it at idle. Ensure fluid has reached normal operating temperature.
2. Attach a spring scale at lock nut of tie rod end. Check steering gear for rack sliding force around neutral position of rack stroke. Slowly pull tie rod in a range of 0.5" (11.5 mm). Observe spring scale reading. If rack sliding force is not within specified range, overhaul steering gear assembly.
**RACK SLIDING FORCE SPECIFICATIONS (Checked at neutral point of rack stroke)**

====''LUBRICATION''====
==''CAPACITY AND FLUID TYPE''==
Fluid capacity is approximately 1 qt. (.9L) for all models.
~-Nissan S13 240SX: Dextron-II ATF
==''FLUID LEVEL CHECK''==
Check fluid level when fluid is cold with engine off. To check and fill, remove fluid level gauge from reservoir and check fluid level. Fluid should be between MIN and MAX marks on the gauge dipstick. Add fluid through dipstick opening (as needed), and recheck. DO NOT overfill.
==''HYDRAULIC SYSTEM BLEEDING''==
DO NOT hold steering wheel at or near lock position for more than 15 seconds.
1. Raise and support vehicle. While adding fluid, turn steering wheel quickly from lock to lock until fluid level no longer decreases and no bubbles exist.
2. Start engine and allow to idle. Repeat step 1). Perform procedure until fluid level no longer decreases and no bubbles exist.
==''HICAS SYSTEM BLEEDING''==
DO NOT allow power steering fluid to drop below inlet port of reservoir during bleeding procedure.
1. Raise and support vehicle so that wheels are free to rotate. Have an assistant sit in driver's seat. With ignition off, move shift lever to Park or Neutral position (A/T) or Neutral position (M/T). Turn ignition on and immediately start engine.
2. Within 10 seconds after starting engine, turn steering wheel at least 20 degrees right and left from neutral position (at least 5 times) and depress and release brake pedal (at least 5 times). Set steering wheel to a point approximately 10 degrees from neutral position. Ensure rear wheels turn left and right alternately.
3. Return steering wheel to neutral position. With engine idling, turn steering wheel 180 degrees to right. Loosen right power cylinder bleeder screw to bleed air, then retighten. Return steering wheel to neutral position.
4. Turn steering wheel 180 degrees to left. Loosen left power cylinder bleeder screw to bleed air, then retighten. Return steering wheel to neutral position. Turn ignition off. Check and refill fluid reservoir as necessary.
====''ADJUSTMENTS''====
==''POWER STEERING PUMP BELT''==
**FYI: Check belt deflection with engine cold.**
With engine cold, apply 22 lbs. (10 kg) pressure on belt at center distance between pulleys and note belt deflection. Adjust belt tension if belt deflection is not within specification.
**BELT ADJUSTMENT SPECIFICATIONS*
Nissan S13 240sx
~-Used Belt (With 22 lbs. pressure applied midway on longest belt run) Deflection In. (mm): .30-.34 inches (7.5-8.6mm)

==''STEERING WHEEL TURNING TORQUE''==
1. Park vehicle on dry, level surface. Ensure tire pressure is correct. Apply parking brake. Start and run engine until fluid temperature is 140-176°F (60-80°C). Attach spring scale to steering wheel.
2. Measure steering wheel turning torque after steering wheel has been turned 360 degrees from center position. Turning torque should be less than 9 lbs. (4.1 kg). If turning torque is not within specification, check rack sliding force to determine condition of steering gear.
