• Measure the outer diameter of t
he camshaft journal using suitable
tool (A).
Inner Diameter of Camshaft Bracket
• Tighten the camshaft bracket bolts to the specified torque following
the tightening pattern as shown.
• Using inside micrometer (A), measure inner diameter of camshaft bracket (1).
Calculation of Camshaft Journal Clearance
• (Journal clearance) = (inner diameter of camshaft bracket) – (outer diameter of camshaft journal)
• When out of the specified range above, replace either or both the camshaft and the cylinder head assembly.
NOTE:
Inner diameter of the camshaft bracket is manufac tured together with the cylinder head. If the camshaft
bracket is out of specification, replace the whole cylinder head assembly.

CAUTION:
• Do not disassemble drive plate.
• Do not place drive plate with signal plate facing down.
• When handling the signal plate, take care not to damage
or scratch it.
• Handle the signal plate in a manner that prevents it from becoming magnetized.
INSTALLATION
Installation is in the reverse order of removal.
• When installing the drive plate to the crankshaft, use the triangle shaped match mark (A) as shown to correctly align the crankshaft
side dowel pin to the drive plate side dowel pin hole.
• Install the drive plate and drive plate reinforcement plate in the direction as shown.
• Tighten the drive plate bolts in a diagonal pattern in two steps. Refer to EM-224, "Disassembly and Assembly"
