(2) (Intake)
If the seating is too low on the valve face, use 70°
and 45° cutters to correct the seat.
(Exhaust)
If the seating is too low on the valve face, use 60°
and 45° cutters to correct the seat.
(d) Hand-lap the valve and valve seat with an abrasive
compound.
(e) After hand-lapping, clean the valve and valve seat.
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 vernier calipers, measure the free length of the
valve spring.
Free length:
Yellow painted mark 46.20 mm (1.8189 in.)
Blue painted mark 49.14 mm (1.9346 in.)
If the free length is not as specified, replace the valve
spring.
(c) Using a spring tester, measure the tension of the valve
spring at the specified installed length.
Installed tension:
30.7-33.9 kg (67.7-74.7 Ib, 301 -332 N)
at 37.0 mm (1.457 in.)
If the installed tension is not as specified, replace the valve
spring.
