INSPECTION BEFORE DISASSEMBLY
Disassemble the power steering oil pump only if the following items are found.
• Deformed or damaged pulley, bracket, connector or suction pipe
• Oil leakage from the suction pipe or connector.
DISASSEMBLY
NOTE:
Mount the power steering oil pump in a vise as needed.
1.
Remove the connector bolt, connector and copper washers.
CAUTION:
Do not reuse the copper washers.
2.
Remove the suction pipe and O-ring.
CAUTION:
Do not reuse the O-ring.
3.
Remove the pulley nut and pulley.
4.
Remove the bracket bolts and bracket(s).
INSPECTION AFTER DISASSEMBLY
Body Assembly Inspection
Check the power steering oil pump body assembly for damage. If any damage is found, replace with a new
power steering oil pump assembly.
ASSEMBLY
Assembly is in the reverse order of disassembly.
CAUTION:
• Do not reuse the copper gaskets
• Do not reuse the O-ring. Apply a coat of Genuine NISSAN PSF or equivalent to the O-ring. Refer to
MA-10, "Fluids and Lubricants"
.

CAUTION:
• Secure the gear housing assembly with a vise. Use copper plates or equivalent to prevent it from
being damaged. Do not grip the cylinder with a vise.
• Before performing disassembly, clean the gear housing assembly. Be careful not to allow any
cleaner to contact the discharge and return port connectors.
DISASSEMBLY
1.
Remove the cylinder tubes from the gear housing assembly.
2.
Loosen the lock nuts of the outer sockets, then remove the outer sockets from the inner sockets.
3.
Remove the boot clamps from the boots, then remove the boots from the inner sockets and gear housing
assembly.
CAUTION:
• Do not reuse the large-diameter boot clamps.
• Do not damage the boots, inner socket or gear housing assembly. If they are damaged, replace
them.
4.
Remove the inner sockets.
INSPECTION AFTER DISASSEMBLY

Gear Housing Assembly
Check gear housing assembly for dents, cracks or damage. Replace as an assembly if necessary.
Outer Socket and Inner Socket
SWING TORQUE
• Measure the swing torque, using Tool. When ball stud and inner
socket start moving the measured value must be within the specifi-
cation. If the reading is outside the specification, replace the
socket.
ROTATING TORQUE
• Measure the rotating torque, using Tool. If the value is outside the
specification, replace the outer sockets.
AXIAL END PLAY
• Apply a load of 490 N (50 kg-f, 110 lb-f) to the ball stud axially. Use
a dial gauge to measure the amount of the movement that the stud
makes. If the value is outside the specification, replace the sock-
ets.
ASSEMBLY
1.
Install the inner sockets.
