Cylinder Block and Crankcase Cover
•
Verify that a crankshaft or the camshaft that requires an axial play
adjustment shim is provided with an adjustment shim. (Refer to the
section on Axial Play Adjustment.)
•
Verify that the governor weight is closed. Also verify that the governor
arm is positioned so that its front receives the end of the governor
sleeve. (Refer to the section on Governor Mechanism.)
•
Install the crankcase cover while paying attention to the meshing of
the governor gear, evenly tighten the retaining bolts in the sequence
given in the diagram, and tighten them to the specified torque. (Refer
to the section on Tightening Torque Specifications.)

it to dry. Then, apply engine oil and gently spin it with your hand.
If the bearing is noisy, does not spin smoothly, or has excessive play,
replace the bearing.
