9. INSPECT VALVE STEMS AND GUIDE BUSHINGS
(a) Using a caliper gauge, measure the inside diameter of the
guide bushing.
Bushing inside diameter:
5.510 ± 5.530 mm (0.2169 ± 0.2177 in.)
(b) Using a micrometer, measure the diameter of the valve
stem.
Valve stem diameter:
Intake5.470 ± 5.485 mm (0.2154 ± 0.2159 in.)
Exhaust5.465 ± 5.480 mm (0.2152 ± 0.2157 in.)
(c) Subtract the valve stem diameter measurement from the
guide bushing guide bushing inside diameter measure-
ment.
Standard oil clearance:
Intake0.025 ± 0.060 mm (0.0010 ± 0.0024 in.)
Exhaust0.030 ± 0.065 mm (0.0012 ± 0.0026 in.)
Maximum oil clearance:
Intake0.08 mm (0.0031 in.)
Exhaust0.10 mm (0.0039 in.)
If the clearance is greater than maximum, replace the valve and
guide bushing.
10. 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: 1.0 mm (0.039 in.)
Minimum margin thickness: 0.5 mm (0.020 in.)

(d) Check the valve overall length.
Standard overall length:
Intake95.45 mm (3.5779 in.)
Exhaust95.40 mm (3.7559 in.)
Minimum overall length:

Exhaust94.90 mm (3.7362 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder or
replace the valve.
NOTICE:
Do not grind off more than minimum.
11. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:

If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.

If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.

Check that the seat contact is in the middle of the
valve face with the following width:
1.0 ± 1.4 mm (0.039 ± 0.055 in.)
If not, correct the valve seats as follows:
(1) If the seating is too high on the valve face, use 30°
and 45° cutters to correct the seat.

Using a micrometer, measure the journal diameter.
Journal diameter:
Intake26.949 ± 26.965 mm (1.0610 ± 1.0616 in.)
Exhaust26.959 ± 26.975 mm (1.0613 ± 1.0620 in.)

ance.
