POWER STEERING FLUID
Revision: 2007 April2007 M35/M45
POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelNGS000D5
Check fluid level with engine stopped.
Make sure that fluid level is between MIN and MAX.
Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
The fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.
Do not reuse drained power steering fluid.
Recommended fluid is Genuine Nissan PSF or equiva-
lent.
Checking Fluid LeakageNGS000D6
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run engine until the fluid temperature reaches 50 to 80° C (122
to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
3. Hold steering wheel at each lock position for five seconds and
carefully, check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not overtighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-30, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid indicating from steering gear.
Air Bleeding Hydraulic SystemNGS000D7
If air bleeding is not complete, the following symptoms can be observed.
Bubbles are created in reservoir tank.
Clicking noise can be heard from oil pump.
Excessive buzzing in the oil pump.
NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of
the system.
1. Turn steering wheel several times from full left stop to full right stop with engine off.
CAUTION:
Filling reservoir tank with fluid so as not to lower fluid level below the MIN line while steering
wheel turning.
2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Do not hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that oil pump may be damaged.)
4. Check fluid for bubbles and while contamination.HOT : Fluid temperature 50 - 80 °C (122 - 176°F)
COLD : Fluid temperature 0 - 30°C (32 - 86°F)

DISASSEMBLY
NOTE:
Secure oil pump in a vise if necessary.
CAUTION:
Use copper plates when securing in a vise.
1. Remove rear cover mounting bolts, and then remove rear cover from body assembly.
2. Remove gasket from body assembly.
3. Remove dowel pin, cartridge and side plate from body assembly.
4. Remove pulley mounting nut and washer, then remove pulley from drive shaft.
5. Remove snap ring from drive shaft and press out it.
CAUTION:
When removing snap ring, be careful not to damage drive
shaft.
6. Remove oil seal from body assembly using a flat-bladed screw-
driver.
7. Remove O-ring from body assembly.
8. Remove lock nut, and then remove copper washer, joint and O-
ring.
9. Remove connector bolt, and then remove O-ring, flow control
valve and spring from body assembly
10. Remove mounting bolts of suction pipe, and then remove suc-
tion pipe from body assembly.
11. Remove O-ring from body assembly.
INSPECTION AFTER DISASSEMBLY
Body Assembly and Rear Cover Inspection
Check body assembly and rear cover for internal damage. Replace rear cover if it is damaged. Replace oil
pump assembly if body assembly is damaged.
Cartridge Assembly Inspection
Check cam ring, rotor and vane for damage. Replace cartridge assembly if there are.
Side Plate Inspection
Check side plate for damage. Replace side plate if there are.
