3.5 Camshaft
The camshaft is a main driving unit of the valve train. There are the air inlet cam, the exhaust cam,
and the cam journal on the shaft. It controls the intake and exhaust valves to open and close at the
correct time. The camshaft wear will affect the engine performance and cause excessive noise.
3.5.1 Removal
a) Loosen the valve cover bolts and remove the cover.
b) Remove the cam chain tensioner screw and the O-ring.
c) Tighten the cam chain tensioner-adjusting bolt clockwise.
d) Turn the flywheel counterclockwise to make the "T" mark on
the flywheel align with the mark on the crankcase. When the
hole on the cam chain (timing drive chain wheel) is up, it is the
top dead center position.
e) Remove the cylinder head positioning bolt;
Remove the camshaft holder bolt cap and washer.
Valve clearance
0.06~0.07 mm
Sometimes when tightening the lock nuts, it will change the clearance. So it must be
rechecked for the proper clearance.
