Checking and Machining
1. Clean the valves and do visual check.
Valves with wobbled valve disc, with worn or scored
valve stem should be replaced.
2. Measure valve disc height ’h’.
Service data
Intake
1.7 ± 0.15 mm
Service data
Exhaust
1.7 ± 0.15 mm
3. Machine the valve.
Notice
Pay attention to setting angle ’a’.
4. Measure radial runout between valve stem and
valve seat.
Limit
Max. 0.03 mm

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
10. Measure distance ’z’ (cylinder head cover parting
surface -- valve stem).

11. The distance ’x’ (camshaft basic bore -- valve stem).
’x’ = ’z’ -- ’y’.
Determine the valve to use according to this mea-
surement (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.
