Do not reuse the oil seals.
CYLINDER HEAD DISTORTION
Decoke the combustion chambers.
Check the gasketed surface of the cylinder head for distortion using
a straightedge and a thickness gauge. Take measurements at the
positions shown in the figure. If the maximum reading at any posi-
tion exceeds the specified limit, replace the cylinder head.
Specific tool: Thickness gauge
Service limit
Cylinder head distortion: 0,05 mm (0.00197 in)
VALVE STEM RUNOUT
Support the valve with V-blocks and check its runout with a compa-
rator.
Replace the valve if the runout exceeds the specified limit.
Specific tools:
Comparator
(1/100 mm, 10 mm)
(0.039/3.937 in, 0.3937 in)
Magnetic stand
800096650: V-blocks
Service limit
Valve stem runout: 0,05 mm (0.00197 in)
VALVE HEAD RADIAL RUNOUT
Place the comparator at right angles to the valve head face, and
measure the radial runout.
If it exceeds the specified limit, replace the valve.
Specific tools:
Comparator
(1/100 mm, 10 mm)
(0.039/3.937 in, 0.3937 in)
Magnetic stand
800096650: V-blocks
Service limit
Valve head radial runout: 0,03 mm (0.00118 in)
VALVE SEAL SURFACE WEAR
Visually inspect the seal surface of each valve for signs of wear.
Replace any abnormally worn valve. Thickness T decreases as wear
increases.
Measure the thickness and, if it is less than specified, replace the
valve.
Specific tool: Caliper
Service limit
Valve head thickness T: 0,5 mm (0.0197 in)
