(1) Piston
(2) Fuse |
- Remove the cylinder head.
- Move up the piston and attach a strip of fuse on the piston head at three positions with grease.
- Lower the piston and install the cylinder head.
Note: Use a new cylinder head gasket and tighten the bolts to the proper torque.
- Turn the flywheel until the piston goes more than the top dead center.
- Remove the cylinder head and measure the thickness of the fuses.
- If the measurement is out of the factory specifications, examine the oil clearances between the crankpin and bearing. Also examine that between the piston pin and bushing.
Note: After you examine the top clearance, make sure that you assemble the cylinder head with a new cylinder head gasket.
