now available
in two
different thick-
nesses
to set
piston
to
cylinder head
•clearance. The thicker head gasket
is to
be used
on
engines that were equipped
with both
a
gasket and shims. The thin-
ner gasket
is to
be used on engines that
were equipped with
a
gasket
and no
shims.
For
identification purposes,
the
last four digits
of
head gasket part
number
are
stamped
on
the gasket.
On 1100, 1210, 1310, 1510, 1710, 1910
and 2110 models, head gaskets
of
differ-
ent thicknesses
are
available
for
serv-
ice
and
selection
of
correct gasket
thickness
is
based
on the
distance pis-
tons protrude above face
of
cylinder
block
at
TDC.
Use a
dial indicator
or
other suitable means to measure height
of each piston above cylinder block sur-
face as shown
in
Fig. 50. Use the meas-
urement from piston that
has the
highest protrusion
and
select
ap-
propriate thickness head gasket
as in-
dicated
in
chart shown
in
Fig.
51.
NOTE:
On 1210 and 1310 models, the
head gasket thickness is stamped on the
top face of the gasket. On all other
models, the last four digits of head gasket
part number are stamped on top face of
gasket.
Install head gasket with side marked
TOP facing
up.
