named as follows:
●Refer to the figure for intake and exhaust valve arrangement.
(The camshafts have, alternately, either an intake valve or an
exhaust valve.)

Camshaft Oil Clearance
Measure by using a micrometer.
Camshaft Bracket Inner Diameter
●Install camshaft bracket and tighten bolts to the specified torque.
●Measure inner diameter of camshaft bracket using an inside
micrometer.
Camshaft Oil Clearance Calculations
(Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal outer diameter)
●If it exceeds the standard value, refer to the standard value of each unit, then replace the camshaft and/or
cylinder head.
NOTE:
As the camshaft bracket is manufactured with the cylinder head, it is impossible to replace only the cam-
shaft bracket.
Camshaft End Play
●Set the dial gauge to the front end of the camshaft. Measure the
end play by moving the camshaft in the direction of the axle.
●If end play exceeds the limit, replace camshaft and measure
camshaft end play again.
●If end play still exceeds the limit after replacing camshaft,
replace cylinder head.Camshaft journal outer diameter:

Visual Inspection of Valve Lifter and Adjusting Shim
●Check lifter side for any signs of wear or damage. Replace if
there are any abnormalities.
●Check cam nose contact and sliding surfaces for wear and
scratches. Replace if there are any abnormalities.
Valve Lifter Bore Diameter
Measure the outer diameter of the valve lifter with a micrometer.
Valve Lifter Inner Diameter
Measure the bore diameter of the cylinder head valve lifter with an
inside micrometer.
Valve Lifter Clearance Calculations
