STANDARD PROCEDURE
STANDARD PROCEDURE - CYLINDER HEAD
BOLT INSPECTION
(1) Measure cylinder head bolts between points
shown (Fig. 11).
Cylinder Head
BoltsThread
Diameter12 M
Length When
New102 mm
Maximum
Length104 mm
(2) If the cylinder head bolt length is greater than
the maximum allowable measurement, replace the
cylinder head bolts.
STANDARD PROCEDURE - MEASURE
CYLINDER HEAD SURFACE
NOTE: Only resurface cylinder head contact surface
if porous or damaged. IT IS NOT necessary to
rework minor variations in flatness in the longitudi-
nal direction.
(1) Disconnect negative battery cable.
(2) Remove cylinder head (Refer to 9 - ENGINE/
CYLINDER HEAD - REMOVAL).
(3) Remove valves.
(4) Inspect cylinder head contact surface for flat-
ness, porous and damage.
(5) Using a straight edge, measure cylinder head
and cylinder block flatness.
(6) Measure cylinder head height at point (1) indi-
cated and retain reading (Fig. 12).NOTE: The camshaft housing Must Not be
machined. Basic bore of the camshaft bearings will
be altered.
(7) Machine cylinder head contact surface, if nec-
essary.
(8) Measure cylinder head height (1) at point indi-
cated, record stock removal (Fig. 12) CYLINDER
HEAD SPECIFICATIONS.
(9) Measure valve setback at points (2) indicated
(Fig. 12) CYLINDER HEAD SPECIFICATIONS.
NOTE: If measurement is less than dimension ª2º
no further correct valve clearance compensation is
possible; replace valve seat ring or cylinder head if
measurement is greater than specification.
