4. Check the axial clearance of the intake/
exhaust camshaft
(a). Remove all the valves.(Refer to"Chapter
12B Engine Mechanical System
Valve,Replacing")
(b). Install the the intake/exhaust camshafts on
the cylinder head and screw the bolt to the
torque required.
(c). Install the micrometer on the camshaft
end, fix the cylinder head and promote the
camshaft in the axial direction to measure 12B
the axial clearance of the camshaft.
Standard axial clearance:
Intake Camshaft:0.05~0.15mm
Exhaust Camshaft:0.05~0.15mm
Limit axial clearance:
Intake Camshaft:0.3mm
Intake Camshaft:0.3mm
• If the measured value is out of the standard clearance range, replace the bearing cap of
the camshaft, and replace the cylinder head if necessary.
