ing positions on cylinder block and main bearing caps.
b. Install thrust bearings on both sides of No. 3 housing on cylinder
block.
●Install thrust bearings with oil groove facing to crankshaft arm
(outside).
c. Being careful with the direction, install main bearings.
●Install main bearings with the oil holes and grooves onto the
cylinder block side, and those without oil holes and grooves
onto the main cap side.
●While installing bearings, apply engine oil to bearing surfaces
(inside). Do not apply engine oil to rear surfaces, but clean
them completely.
●Align stopper notches on bearings to install them.
●Check that the oil holes on the cylinder block body are mated
with the oil hole positions on the bearings.
5. Install crankshaft to cylinder block.

●Identify main bearing caps by the punched mark. Install cor-
rectly matching the journal No. on the bearing cap and the
journal with the front mark facing forward.
●Main bearing caps are commonly processed with the cylinder

How to Select Piston and BearingEBS00ODY
DESCRIPTION
●The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
●For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.
●For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, refer to the text.
HOW TO SELECT PISTON
When Using New Cylinder Block
1. Identify the cylinder bore grade (No. 1, 2, or 3) on LH surface at
the rear of cylinder block.
2. Select the piston of the same grade.
●The part No. of piston is specified together with the piston pin
as an assembly.
