(b) Check the valve seating position.
Apply a thin coat of Prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do
not rotate the valve.
(c) Check the valve face and seat for the following:
wIf blue appears 360° around the face, the valve is con-
centric. If not, replace the valve.
wIf blue appears 360° around the valve seat, the guide
and are concentric. If not, resurface the seat.
wCheck 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.) (d) Check the valve overall length.
Standard overall length:
Intake 100.60 mm (3.9606 in.)
Exhaust 100.45 mm (3.9547 in.)
Minimum overall length:
Intake 100.1 mm (3.941 in.)
Exhaust 100.0 mm (3.937 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 the minimum.
12. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.

13. INSPECT VALVE SPRINGS
(a) Using a steel square, measure the squareness of the valve
spring.
Maximum squareness: 2.0 mm (0.075 in.)
If squareness is greater than maximum, replace the valve
spring.
(b) Using calipers, measure the free length of the valve
spring.
Free length: 45.0 mm (1.772 in.)
If the free length is not as specified, replace the valve
spring. (d) Hand±lap the valve and valve seat with an abrasive
compound.
(e) After hand±lapping, clean the valve and valve seat. 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.
(2) If the seating is too low on the valve face, use 75°
and 45° cutters to correct the seat.

If the overall length is less than minimum, replace the
valve. (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.)
If the margin thickness is less than minimum, replace
the valve.
(e) Check the surface of the valve stem tip for wear.

GENERAL MAINTENANCE
These are the maintenance and inspection items
which are considered to be the owner's responsibility,
They can be performed by the owner or he
can have then done at a service shop. These items
include those which should be checked on a daily ba-
