1998 NISSAN PATROL oil

Assembly
Assemble oil pump, noting the following instructions.
+Make sure O-rings and oil seal are properly installed.
+Always install new O-rings and oil seal.
+Be careful of oil seal direction.
+Cam ring, rotor and vanes must be replaced as a set if neces-
sary.
+When assembling, coat each part with ATF.
+Pay attention to the direction of rotor.
+When assembling vanes to rotor, rounded surfaces of vanes
must face cam ring side.
+Insert pin
V2into pin grooveV1of front housing and front side
plate. Then install cam ring
V3as shown at left.

Disassembly
TIE-ROD
When tie-rod ball joints and tie-rod bar are separated, adjust tie-rod
length correctly.
Adjustment should be done between ball stud centers.
L: Standard
1,302 mm (51.26 in)
CAUTION:
+Make sure that tie-rod ball joints are the same length as to
the left and right.
+The toe-in must be adjusted to within dimension ``L'' 5 mm
(0.20 in).
DRAG LINK
When drag link ball joints and drag link bar are separated, adjust
drag link length correctly.
Adjustment should be done between ball stud centers.
L: Standard
1,123.4 mm (44.23 in)
CAUTION:
+Make sure that drag link ball joint and adjuster are turned
to the same length.
+The neutral position must be adjusted to within dimension
``L'' 1 mm (0.04 in).
Inspection
BALL JOINT
1. Check joints for play. If ball is worn and play in axial direction
is excessive or joint is hard to swing, replace as a complete
unit.
Swinging force (Measure point: Cotter pin hole) ``A'':
4.9 - 49.0 N (0.5 - 5.0 kg, 1.1 - 11.0 lb)
Rotating torque ``B'':
0.3 - 2.9 Nzm (3 - 30 kg-cm, 2.6 - 26.0 in-lb)
Axial end play ``C'':
0mm(0in)
2. Check condition of dust cover. If it is cracked excessively,
replace as a complete unit.
CAUTION:
Be careful not to apply grease or oil to taper of joint.

TIE-ROD AND DRAG LINK
Check tie-rod and drag link for breakage, bends and cracks, and
replace with a new one if necessary.
FIXING LOCATION
+Check ®xing location (nuts and cotter pins) for looseness, play
and breakage.
+When looseness or play is found, check for wear and tapered
portion of ball joints, pitman arm and knuckle arms.
+When reassembling each joint, use new cotter pins.
STEERING DAMPER
Check for oil leakage and measure damping force. Replace if nec-
essary.
Damping force:
at 0.3 m (1.0 ft)/sec
4,443 N (453 kg, 999 lb)
... Extended direction
3,315 N (338 kg, 745 lb)
... Compressed direction
