to a temperature of about 1<strong>50</strong> °C, 302 °F (~10<br />
minutes heating time), and complete the fitting of the<br />
connecting rod group in the rh crankcase, as described<br />

crankshaft fitting tool, using the tool to bring the two<br />
crankcase halves together .<br />
NOTE: While holding the connecting rod at top<br />
dead center with one hand, turn the nut on the<br />
tool with the other hand until the two crankcases<br />
are gently in contact.<br />

in a “X” pattern tightening sequence.<br />
