(When reassembling)
IMPORTANT
Q
• Make sure the crankcase 1 and 2 are clean.
• Apply liquid gasket (Three Bond 1217D) to the crankcase 2
as shown in the figure.
• Tighten the crankcase 2 mounting screws with even force on
the diagonal line.
• Confirm that the liquid gasket coating surface is free of
water, dust and oil in order to maintain sealing effect.
• Carefully apply the adhesive evenly.
NOTE
Q
• When mounting the adhesive-applied parts, take care to fit
them to the mating parts.
• Assemble the adhesive-applied parts within ten minutes.

Crankcase 1 and Crankcase 2
(When reassembling)
• Match the crankcase 1 and 2, referring to the flywheel housing’s
contoured face.
• Tighten the crankcase 2 mounting screws loosely.
• Tighten up the jig to the specified torque same as the flywheel
housing screw. This helps to minimize the level difference
between the crankcase 1 and the crankcase 2 (at the flywheel
side). Possible gap must be 0.05 mm (0.002 in.) or smaller.
