11. The distance ‘x’ (camshaft basic bore - valve
stem).
‘ x ’ = ‘ z ’ - ‘ y ’ .
Determine the valve to use according to this
measurement (See ‘matching valves’)
Example) Measured value ‘w’ = 38.2 mm
Measured value ‘z’= 36.5 mm
V a l u e ‘ y ’
= 15.5 mm
‘x’ = 36.5 - 15.5 = 21.0 mm
In this case according to ‘Matching valves’ table,
the installed valve may be used.

Machining Procedure
Valve machining is required :
-
When the valve is leaking.
-
When replacing the valve.
-
When replacing the valve guide.
-
When replacing the valve seat or valve seatring.
1. Machine the valve seat (
α
=45°).
4. Measure radial runout.
2. Measure valve seat width ‘b’.
