CYLINDER HEAD GASKET INSTALLATION
(1) In case any of the cylinder block, piston, connecting rod
and crankshaft has not been replaced, install the gasket
of the same rank as before which can be identified by
the mark shown in the illustration at left.
(2) In case any of the cylinder block, piston, connecting rod
and crankshaft have been replaced, reselect and install
the gasket in accordance with the following procedure.
1 With each piston held at the top dead center, measure
its protrusion from the upper block surface at the
locations shown in the illustration at left (total of eight
locations). Be sure to take measurements on the
crankshaft center line.
2 Using the average of the eight measurements, select
the gasket rank (A, B or C) in accordance with the
table given below. If, however, the maximum protrusion
at any one location exceeds the protrusion tolerance
shown for any rank in the following table, use the
gasket one rank higher that rank.
