2. Install each plug to the cylinder block (only screw-type plugs are

shown).

• Apply liquid gasket.

Use Genuine Thread Sealant or equivalent. Refer to

GI-15,

• Replace copper washers with new ones.

• Tighten each plug as specified below.

3. Install main bearings and thrust bearings.
a. Remove any dust, dirt, and oil on the bearing mating surfaces of

the cylinder block and main bearing caps.

b. Install thrust bearings to both sides of the No. 3 journal housing

on the cylinder block and main bearing caps

• Install thrust bearings with the oil groove facing the crankshaft

arm (outside).

• Install thrust bearings with a protrusion in the center on the

main bearing caps.

Install main bearings paying attention to the direction.

• Install the one with oil holes onto the cylinder block and the

one without oil holes onto the main bearing cap.

• Before installing bearings, apply engine oil to bearing surface

(inside). Do not apply oil to the back surface, but thoroughly

clean it.

• When installing, align the bearing stopper to the notch.

• Ensure the oil holes on the cylinder block and those on the

corresponding bearing are aligned.
