• Cut with both hands touniform thecutting surface.
REPLACING VALVESEATFORSERVICE PARTS

1. Bore outoldseat until

Installation (Cont'd)

• Apply sealing compound (THREE-BOND No.10or equiva-
lent) toboth ends ofbrackets No.1andNo.5.

Selecting cylinderheadgasket
When replacing onlycylinder headgasket, installthesame
grade (Number ofnotches) gasketasthe one formerly used.

Step 1
Measure projection ofpiston tocylinder headsurface.
a) Set dial gauge andneedle oncylinder blockandadjust dial
gauge tozero.
b) Set dial gauge needle atmeasuring pointonpiston, taking
care nottodisturb itszero setting.
c) Rotate crankshaft aroundthetopdead center position.
d) Read andwrite down themaximum value.
e) Reset dialgauge oncylinder blockandconfirm thatzero
setting hasnotbeen disturbed duringmeasurement.
f) Repeat stepsbthrough dfor allmeasuring pointsasillus-
trated andforeach cylinder.
• Besure thatpiston whose projection isbeing measured is
at its TDC.
Step 2
Calculate theaverage valueofmeasurements takenforeach
piston.
Step 3
Calculate theaverage valueofmeasurements forallpistons
from thevalues obtained fromstep2.
Step 4
Round offthe value obtained.
Step 5
Determine requiredthickness ofgasket, referring tochart

Make following checks.Adjust,repairorreplace ifnecessary.
• Check tiresforwear andforimproper inflation.
• Check rearwheel bearings forexcessive play.
• Check wheelrunout.

CAMBER
Camber ispreset atfactory andcannot beadjusted.
Camber: Refer toSOS (RA-12).

• Ifthe camber isnot within specification, inspectandreplace
any damaged orworn rearsuspension parts.

TOE-IN
Toe-in ispreset atfactory andcannot beadjusted.
Measure toe-inusingfollowing procedure. Ifout of
specification, inspectandreplace anydamaged orworn rear
suspension parts.
WARNING:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before
pushing it.

1. Bounce rearofvehicle upand down tostabilize theposture.
2. Push thevehicle straight aheadabout5m (16
ft).

3. Putamark onbase lineofthe tread (rearside) ofboth tires at
the same height ofhub center. Thismark isameasuring point.
4. Measure distance"A"(rear side).
5. Push thevehicle slowlyaheadtorotate thewheels 180
degrees (1/2turn).

If the wheels haverotated morethan180degrees (1/2turn), try
the above procedure againfromthebeginning. Neverpush
vehicle backward.

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