Oil Pan and Oil Strainer
1. Remove the oil pan mounting screws.
2. Remove the oil pan (4) by lightly tapping the rim of the pan with
a wooden hammer.
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.
• To avoid uneven tightening, tighten oil pan mounting screws in
diagonal order from the center.
IMPORTANT
• Scrape off the old adhesive completely. Wipe the sealing
surface clean using waste cloth soaked with gasoline. Now
apply new adhesive 3.0 to 5.0 mm (0.12 to 0.19 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 bolt
hole.
• Cut the nozzle of the "liquid gasket" (Three bond 1207D or
equivalent) container at its second notch. Apply "liquid
gasket" about 5.0 mm (0.19 in.) thick. Within 20 minutes
after the application of liquid gasket, reassemble the
components. Wait then for about 30 minutes, and pour oil
in the crankcase.
