Valve Seat Inspection
•
Remove the valve (see Valve Removal).
•
Check the valve seating surface [A] between the valve [B]
and valve seat [C].
○
Measure the outside diameter [D] of the seating pattern
on the valve seat.
If the outside diameter is too large or too small, repair the
seat (see Seat Repair).
Valve Seating Surface Outside Diameter
Standard:
Inlet
29.4
∼
29.6 mm (1.1575
∼
1.1654 in.)
Exhaust 25.2
∼
25.4 mm (0.992
∼
1.000 in.)
○
Measure the seat width [E] of the portion where there is
no build-up carbon (white portion) of the valve seat with a
vernier caliper.
Good [F]
If the width is too wide [G], too narrow [H] or uneven [J],
repair the seat (see Valve Seat Repair).
Valve Seating Surface Width
Standard:
Inlet
