INSTALLATION
1) Clean mating surface of cylinder head and cylinder block.
Remove oil, old gasket and dust from mating surface.
2) Prepare optimum cylinder head gasket according to following
procedure.
a) As shown in figure, piston projects above cylinder block when
it reaches top dead center. Using special tool and dial gauge,
measure projection “b” at two points “A” and “B” and take an
average. Repeat this procedure with each piston.
Special Tool
(A): 09910-26510/OUT 0000005
b) Using the largest value among averages obtained above,
prepare optimum cylinder head gasket referring to table be-
low.
