Check the valve overall length.
Standard overall length:
Intake: 103.45 mm (4.0728 in.)
Exhaust: 103.60 mm (4.0787 in.)
Minimum overall length:
Intake: 102.95 mm (4.0531 in.)
Exhaust: 103.10 mm (4.0590 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.
12. 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 these:
S
If blue appears 360
˚
around the face, the valve is
concentric. If not, replace the valve.
S
If blue appears 360
˚
around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
S
Check that the seat contact is in the middle of the
valve face with these width:
0.9 -- 1.9 mm (0.035 -- 0.075 in.)
(d)
If not, correct the valve seats as follows:
(1)
Intake:
If the seating is too high on the valve face, use 30
˚
and 45
˚
cutters to correct the seat.
