Notes on installing cooling fan and clutch

  Do not use a tool which locks piston when installing a cooling-fan and clutch, or top of the piston may be damaged. Also, do not insert a screw driver or the similar into the exhaust port.

It is recommended to use Crankshaft Clamp available as an optional tool.

  Do not grip the engine mounting beams with a vise, or the crankcase will be distorted which will result in engine breaking.

Application is as follows:

  Remove the crankcase rear cover plate from the engine and rotate the crankshaft to the bottom dead center (BDC) position.

Insert the crankshaft clamp so that its grooved portion surrounds the crankpin and lower end of the connecting rod and securely tighten the fan or clutch onto the crankshaft.
