(c) Check the valve head margin thickness.
Standard margin thickness:
1.3 – 1.7 mm (0.051 – 0.067 in.)
Minimum margin thickness:
1.0 mm (0.039 in.)
If the margin thickness is less than minimum, replace
the valve.
(d) Check the valve overall length.
Standard overall length:
104.3 mm (4.106 in.)
Minimum overall length:
103.8 mm (4.087 in.)
If the overall length is less than minimum, replace the
valve.
7. 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
(g) Using SST and a hammer, tap in a new guide bushing
until the snap ring makes contact with the cylinder
head.
SST 09201–60011
(h) Using a sharp 8 mm reamer, ream the guide bushing
to the obtain standard specified clearance (See step 5
above) between the guide bushing and valve stem.
