CONNECT-
ING ROD SIDE CLEARANCE" .
a. Move crankshaft pin to be removed to approximately BDC.
b. Remove connecting rod caps.
c. Using the grip of a hammer, press the piston and connecting rod
assembly out to cylinder head side.
CAUTION:
When removing the piston and connecting rod assembly,
prevent the big end of the connecting rod from interfering
with the oil jet.

●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.
