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 seat ring.

1. Machine the valve seat (a=45_).

2. Measure valve seat width ’b’.

width ’b’

Exhaust

1.5 -- 2.0 mm

3. If the specification is exceeded, the valve seat width

has to be corrected at the lower free angle of

’β’=65 .

4. Measure radial runout.

Runout

Max. 0.03mm

5. Insert the valve (1) into the valve guide according to

marking and measure amount by which the valve ar-

rears ’a’.

Arrears ’a’

0.1 -- 0.7mm

6. Measure camshaft cam basic circle diameter (w).

Diameter ’w’

38 ± 0.2mm

or 37.6 ± 0.2mm

7. Measure distance ’z’ (cylinder head cover parting

surface -- valve stem).

I Length of Valve

w Camshaft Cam Basic Circle Diameter

x Distance (Camshaft basic bore -- valve stem)

y Half Camshaft Basic Bore Diameter

z Distance (Cylinder head cover parting surface --

valve stem)

8. Measure ’x’ (Camshaft basic bore -- valve stem).

’x’ = ’z’ -- ’y’

9. Determine the valve to be used.

(See ’Matching valves’)
Example) Measured value ’w’ = 38.2 mm

Measured value ’z’ = 36.5 mm
Value

’y’ = 15.5 mm

’x’ = 36.5 -- 15.5 = 21.0 mm

In the case of a camshaft cam basic circle diameter

’w’ = 38.2mm and a distance ’x’ = 21.0mm, the

installed valve may be used.
