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’ =15.5mm
’x’ = 36.5 -- 15.5 = 21.0mm
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 seat ring.
1. Machine the valve seat (a=45_).
2. Measure valve seat width ’b’.
Va lv e s e a tIntake1.2 -- 1.7 mmValveseat
width ’b’Exhaust1.5 -- 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.
RunoutMax. 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.

Measurement Procedure
1. Remove the cylinder head cover.
2. Rotate the engine in the direction of engine rotation
until the intake valve of NO.1 cylinder is completely
closed. The cam lobe faces up (arrow).
Notice
Do not rotate the engine at the bolt of the crankshaft
sprocket. Do not rotate the engine in the opposite di-
rection of engine rotation. If do, thiswill cause seri-
ous measuring errors.
3. Install the dial gauge holder and dial gauge (7) with
the extension (8) to the cylinder head and position
the tracer pin (9) onto the valve tappet (intake valve
of cylinder NO.1) with a preload of min. 3mm.
Notice
The tracer pin should be positioned exactly vertical.

4. Set the dial gauge to ’0’.
5. Rotate the engine further in direction of rotation until
the dial gauge has moved back by 2mm (valve lift) to
1mm.
6. Check the timing.

Notice
If timing is out standard, the camshaft should be
checked for wear and the timing chain for stretch. If
adifferenceofmorethan4_exists, the timing chain
should be replaced.
7. Replace the gasket and install the cylinder head
cover.

Removal Procedure
1. Rotate the crankshaft and position the piston of no.1
cylinder at TDC.
Notice
Do not rotate the crankshaft in the opposite direction
of engine rotation.
In this position, the markings of the camshaft/cam-
shaft bearing cap (arrow) must be aligned.
2. Place alignment marks on the camshaft sprocket
and timing chain.
3. Remove the starter motor and install the engine
lock.
