tact with boot.
CAUTION:
Keep gap from cylinder tube 5 mm (0.20 in) or more.
21. Install cylinder tubes to gear housing assembly. Tighten the bolts to the specified torque. Refer to
.
CAUTION:
Never reuse the copper washer.
22. Adjust inner socket to standard length “L”, and then tighten lock
nut to the specified torque. Refer to
Check length of inner socket “L” again after tightening lock nut.
Make sure that the length is the standard.
CAUTION:
Adjust toe-in after this procedure. Length achieved after
toe-in adjustment is not necessary the above value.

RELIEF OIL PRESSURE
CAUTION:
Before starting work, confirm belt tension is proper.
1.
Connect pressure gauge (SST) and pressure gauge adapter
(SST) between power steering oil pump discharge connector
and high pressure hose. Bleed air from the hydraulic circuit
while opening valve fully. Refer to
.
2.
Start engine. Allow engine to run until tank temperature reaches
50 to 80
°
C (122 to 176
°
F).
CAUTION:
●
Warm up engine with shut-off valve fully opened. If
engine is started with shut-off valve closed, fluid pres-
sure in power steering pump increases to maximum. This
will raise fluid temperature excessively.
●
Be careful not to contact hose with belt when engine is started.
3.
Fully close the 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 power steering oil pump is the relief oil pressure is outside
the standard. Refer to
PS-28, "Disassembly and Assembly"
5.
Apply Genuine Nissan PSF or equivalent to around O-ring (1),
then install eye-bolt (2). Install eye-bolt (2) with eye-joint
(assembled to high pressure hose) protrusion (A) facing with
pump side cutout, and then tighten it to the specified torque after
tightening by hand. Refer to
.
6.
After inspection, disconnect the pressure gauge (SST) from
hydraulic circuit, then add fluid and bleed air. Refer to
.
Relief oil pressure:
8,500 - 9,300 kPa (88 - 94 kg/cm
2
, 1,251 - 1,337 psi)
