ENGINE MECHANICAL - Cylinder Head
(d) Using SST and a hammer, tap in a new guide bushing
to where there is 11.8 - 12.2 mm (0.465 - 0.480 in.)
protruding from the cylinder head.
SST 09201-60011
(e) Using a sharp 8 mm reamer, ream the guide bushing to
obtain the standard specified clearance (See page
EM-65) between the guide bushing and valve stem.
11. INSPECT AND GRIND VALVES
(a) Grind the valve enough to remove pits and carbon.
(b) Check that the valve is ground to the correct valve face
angle.
Valve face angle: 44.5°
(c) Check the valve head margin thickness.
Standard margin thickness:
Intake 1.6 mm (0.063 in.)
Exhaust 1.7 mm (0.067 in.)
Minimum margin thickness:
Intake 1.1 mm (0.043 in.)
Exhaust 1.2 mm (0.047 in.)
If the margin thickness is less than minimum, replace the
valve.
(d) Check the valve overall length.
Standard overall length:
Intake 103.29-103.69 mm
(4.0665-4.0823 in.)
Exhaust 103.14-103.54 mm
( 4 . 0 6 0 6 - 4 . 0 7 6 4 in.)
Minimum overall length:
Intake 102.79 mm (4.0468 in.)
Exhaust 102.64 mm (4.0409 in.)
If the overall length is less than minimum, replace the valve.
