10. Measure distance ‘z’ (cylinder head cover parting surface

- valve stem).

5. Clean the vales, valve seats and valve guides.

6. Coat the valve stem with oil and insert it into valve guide.

7. Insert the valves (1) into the valve guides according to

marking.

8. Measure amount by which the valve arrears ‘a’.

Arrears ‘a’

0.1 - 0.7 mm

Notice

If out of standard, replace the valve seat ring.

9. Measure camshaft cam basic diameter (w).

Diameter ‘w’

38 ± 0.2 mm

or  37.6 ± 0.2 mm

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

Value

   ‘y’             = 15.5 mm

‘x’ = 36.5 - 15.5 = 21.0mm

In this case according to ‘Matching valves’ table, the
installed valve may be used.
