2. Remove the oil pan (4).
3. Remove the oil strainer (3).
(When reassembling)
• After cleaning the oil strainer, check to see that the filter mesh in
clean, and install it.
• Visually check the O-ring (1), apply engine oil, and install it.
• Securely fit the O-ring to the oil strainer.
• To avoid uneven tightening, tighten oil pan mounting screws in
diagonal order form the center.
• Scrape off the old adhesive completely. Wipe the sealing
surface clean using waste cloth soaked with gasoline. Now
apply new adhesive 3 to 5 mm (0.12 to 0.20 in.) thick all over
the contact surface. Apply the adhesive also on the center
of the flange as well as on the inner wall of each screw hole.
• Cut the nozzle of the “liquid gasket” container at its second
notch. Apply “liquid gasket” about 5 mm (0.20 in.) thick.
Within 20 minutes after the application of fluid sealant,
reassemble the components. Wait then for about 30
minutes, and pour oil in the crankcase.
