Degrease the surface where the liquid gasket is applied and the contact surface between the cylinder block and ladder frame.

3.Squeeze liquid gasket of Φ2.5 ± 0.5 mm in thickness and apply it to the illustrated position of the ladder frame.
Specified sealant:
    ThreeBond 1217G or equivalent

4.Tighten the ladder frame to the specified torque of 24 ± 2 N·m in the order shown in the illustration.

>>B<< CRANKSHAFT SPROCKET INSTALLATION



1.Wipe off the dirt on the crankshaft sprocket and the crankshaft using a rag, and then remove the grease from the portion shown in the illustration.
note Remove grease to prevent a drop in the coefficient of friction of the pressing portion caused by adhesion of oil.
