POWER STEERING OIL PUMPPFP:49110
On-Vehicle Inspection and ServiceNGS000DE
CHECKING RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the hydraulic pressure gauge [SST] between oil pump
discharge connector and high-pressure hose. Bleed air from the
hydraulic circuit while opening valve fully. Refer to PS-8, "
Air
Bleeding Hydraulic System" .
2. Start engine. Run engine until oil temperature reaches 50 to
80°C (122 to 176°F).
CAUTION:
Leave the valve of the hydraulic pressure gauge [SST]
fully open while starting and running engine. If engine is
started with the valve closed, the hydraulic pressure in
oil pump goes up to the relief pressure along with
unusual increase of oil temperature.
Be sure to keep hose clear of belts and other parts when
engine is started.
3. Fully close the hydraulic pressure gauge [SST] valve with
engine at idle and measure the relief oil pressure.
CAUTION:
Never keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Repair oil pump if the
relief oil pressure is outside the standard. Refer to PS-31, "
Dis-
assembly and Assembly (Models with VK45DE)" , PS-35, "Disassembly and Assembly (Models with
VQ35DE)" .
5. After inspection, disconnect the hydraulic pressure gauge [SST] from hydraulic circuit, then add fluid and
bleed air. Refer to PS-8, "
Air Bleeding Hydraulic System" .
Removal and InstallationNGS000DF
REMOVAL
1. Drain power steering fluid from reservoir tank.
2. Remove undercover from vehicle with a power tool.
3. Loosen drive belt. Refer to EM-16, "
DRIVE BELTS" (VQ35DE), EM-174, "DRIVE BELTS" (VK45DE).
4. Remove drive belt from oil pump pulley.
5. Remove piping of high pressure and low pressure (drain fluid from their pipings). Refer to PS-39,
"HYDRAULIC LINE" .
6. Remove power steering oil pump mounting bolts, and then remove power steering oil pump. Refer to PS-
39, "Removal and Installation" .
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-39, "HYDRAULIC LINE" .
Perform the following procedure after installing.
–Adjust belt tension (VQ35DE). Refer to EM-16, "Tension Adjustment" .
–About the installation of VK45DE drive belt, refer to EM-174, "Tension Adjustment" .
–Bleed air. Refer to PS-8, "Air Bleeding Hydraulic System" . Relief oil pressure:
8,520 - 9,320 kpa (86.9 - 95.1 kg/cm
2 , 1,235 - 1,351 psi)
