5. Remove RH front wheel.
6. Remove RH splash cover (combined with under cover)
7. Remove front exhaust tube.
8. Remove fuel hose from fuel supply pump.
9. Disconnect the harness connector from the fuel supply pump.
10. Remove the fuel supply pump rear bracket.
●Loosen the fuel bolts in the reverse order of that show in the
figure and remove them.
11. Remove injection tube center.
12. Remove front chain case.
●Loosen fixing bolts in the reverse order of that shown in the
figure and remove them.
●Remove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:
●While front chain case is removed, cover openings to
prevent entry of foreign material into engine.
●Do not remove two mass dampers on the back of
cover.
13. Set the No. 1 piston to TDC on its compression stroke.
●Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.
●No position indicator is provided on the crankshaft pul-
ley.
●When installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
supply pump sprocket may not be easy to see.
14. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with a
push pin.

PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEDS00101
●Before starting diagnosis of the vehicle, understand symptoms well. Perform correct and systematic oper-
ations.
●Check for the correct installation status prior to removal or disassembly. When mating marks are required,
be sure they do not interfere with the function of the parts they are applied to.
●Carry out an overhaul in a clean work place. Using a dust proof room is recommended.
●Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
●Check appearance of the disassembled parts for damage, deformation, and abnormal wear. If a malfunc-
tion is detected, replace it with a new one.
●Normally replace lock pins, oil seals, and bearings with new ones every time they are removed.
●In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
●Clean and flush the parts sufficiently and blow them dry.
●Be careful not to damage the sliding surfaces and mating surfaces.
●When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
●Always use shop paper for cleaning the inside of components.
●Avoid using cotton gloves or a shop cloth to prevent entering of lint.
●During assembly, observe the specified tightening torque, and apply new differential oil, Vaseline, or Nis-
san MP Special Grease No. 2, as specified for each vehicle, when necessary.
●Do not reuse drained oil. Discard waste oil after oil changes or part treatment in accordance with local
laws and regulations.
Precautions for Brake SystemEDS00102
●When installing rubber parts, final tightening must be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
●After installing removed suspension parts, check wheel alignment and adjust if necessary.
●Use flare nut wrench when removing or installing brake tubes.
●Always torque brake lines when installing.

●When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on flat, level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
●“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.
●After installing the removed suspension parts, always check wheel alignment and adjust if necessary.
●Replace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.

On-Vehicle Inspection and Service
EES00072
LOOSENESS, BACKLASH AND DAMAGE OF MOUNTING PARTS AND CONNECTIONS
Lift vehicle and inspect the following:
●Check mounting point of each component for looseness, backlash and damage.
●Check lower ball joint end play.
1. Attach a dial gauge so that the contact rests on the brake caliper.
2. Set front wheels in a straight-ahead position. Do not depress brake pedal.
3. Measure axial endplay by placing an iron pry bar or something similar between transverse link and steer-
ing knuckle.
CAUTION:
Be careful not to damage ball joint boot.
4. If axial endplay is outside the standard, remove transverse link and check lower ball joint.
Wheel AlignmentEES00073
DESCRIPTION
●Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tire, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check lower ball joint axial endplay.
5. Check strut operation.
6. Check each mounting point of axle and suspension for looseness and deformation.
7. Check each link and arm for cracks, deformation, and other damage.
8. Check the vehicle posture.
INSPECTION OF CAMBER, CASTER, AND KINGPIN INCLINATION ANGLES
● Camber, caster, and kingpin inclination angles cannot be adjusted.
●Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so the vehicle will remain horizontal.
1. Measure camber, caster and kingpin inclination of both right and
left wheels with a suitable alignment gauge.
2. If camber, caster or kingpin inclination is not within specification,
inspect front suspension parts. Replace dam-aged or worn out
parts.

Removal and InstallationEES00076
REMOVAL
1. Remove steering knuckle from transverse link. Refer toFAX-7, "REMOVAL" .
2. Remove mounting nuts and washers on lower portion of stabilizer connecting rod.
3. Slightly loosen transverse link mounting bolts.
4. Remove transverse link mounting bolts and nuts, and remove transverse link from suspension member.
INSPECTION AFTER REMOVAL
Visual Inspection
Check transverse link and bushing for deformation, cracks, and other damage. Replace the entire transverse
link assembly if cracks, deformation or any other damage is found.
Ball Joint Inspection
CAUTION:
Before measurement, move the ball joint at least ten times by hand to check for smooth movement.
Swing Torque Inspection
●Hook spring scale at cotter pin mounting hole. Confirm spring
scale measurement value is within specifications when ball stud
begins moving.
●If the value is outside the standard, replace transverse link.
Turning Torque Inspection
●Attach mounting nut to ball stud. Check that turning torque is
within specifications with a preload gauge.
●If the value is outside the standard, replace transverse link.
Axial Endplay Inspection
●Move tip of ball joint in axial direction to check for looseness.
●If any looseness is noted, replace transverse link.
INSTALLATION
●Refer to FSU-5, "Components" for tightening torque. Tighten in the reverse order of removal.
●Tighten transverse link mounting bolts with vehicle unladen and all four tires on flat, level ground.
●After installation, check wheel alignment. Refer to FSU-6, "Wheel Alignment" . Swing force:
0.50 - 3.4 N·m (0.05 - 0.35 kg-m, 5 - 30 in-lb)
