Front Wheel Alignment

Before checking frontwheel alignment, besure tomake apre-
liminary inspection (Unladen*).
*: Fuel, radiator coolantandengine oilfull. Spare tire,jack,
hand tools andmats indesignated positions.

SFA575B PRELIMINARY INSPECTION

1. Check tiresforwear andimproper inflation.
2. Check wheelrunout.

Wheel runout:
Refer toSOS (FA-30).

3. Check frontwheel bearings forlooseness.
4. Check frontsuspension forlooseness.
5. Check steering linkageforlooseness.
6. Check thatstruts workproperly.
7. Check vehicle posture (Unladen).

TOE-IN Measure toe-inusingfollowing procedure.
WARNING:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before
pushing it.

1. Bounce frontofvehicle upand down tostabilize theposture.
2. Push thevehicle straight aheadabout5m (16 ft).
3. Put amark onbase lineoftread (rearside) ofboth tires at
the same height ashub center. Thesearemeasuring points.
4. Measure distance"A"(rear side).
5. Push thevehicle slowlyaheadtorotate thewheels 180
degrees (1/2turn).

If the wheels haverotated morethan180degrees
(112
turn), try
the above procedure againfromthebeginning. Neverpush
vehicle backward.

6. Measure distance"B"(front side).

Total toe-in
Refer toSOS (FA-29).
CAMBER,
CASTERANDKINGPIN INCLINATION
Camber, casterandkingpin inclination arepreset atfactory and
cannot beadjusted.

1. Measure camber,casterandkingpin inclination ofboth right
and leftwheels withasuitable alignment gauge.

Camber, CasterandKingpin inclination:
Refer toSOS (FA-29).

2. Ifcamber, casterorkingpin inclination isnot within
specification, inspectfrontsuspension parts.Replace dam-
aged orworn outparts.

CYLINDER HEADDISTORTION

Clean surface ofcylinder head.
Use areliable straightedge andafeeler gauge tocheck the
flatness ofcylinder headsurface.
Check alongsixpositions showninfigure.

Head surface flatness:
Standard:
Less than0.03mm(0.0012 in)
Limit: 0.1 mm (0.004 in)

If beyond thespecified limit,replace itor resurface it.

Resurfacing limit:
The resurfacing limitofcylinder headisdetermined bythe cyl-
inder block resurfacing inan engine.
Amount ofcylinder headresurfacing is
"A".

Amount ofcylinder blockresurfacing is
"8".

The maximum limitisas follows:

After resurfacing cylinderhead,check thatcamshaft rotates
freely byhand. Ifresistance isfelt, cylinder headmust be
replaced.
