the cylinder block, inside of crankshaft case, and inside of
cylinder bores to remove any foreign materials.
2. Install oil jet relief valves.
3. Install oil jets.
4. Install main bearings and thrust bearings.
a. Remove debris, dust, and oil from the locations on the cylin-
der block and main bearing caps where bearings are
installed.
b. Install thrust bearing on each side of cylinder block No. 3
housing.
+Install thrust bearings with oil groove facing in the direction
of the crankshaft arm (outside).
c. Be sure to install main bearings in the correct direction.
+Make sure those with oil holes or oil grooves are mounted on
the cylinder block side, and those without oil holes or oil
grooves are on the main cap side.
+Before installing, apply engine oil on the front (inner) surfaces
of bearings. Do not apply oil to the back surfaces, but thor-
oughly clean them.
+Align stopper notches on bearings and install.
+Check the oil holes on cylinder block and those on bearings
are aligned.
5. Install crankshaft to cylinder block.
+Make sure crankshaft rotates smoothly by hand.
6. Install main bearing caps.
+Identify main bearing caps by the punched mark. Install
correctly, 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 cylin-
der block. Therefore, caps and cylinder block should be
replaced as a set.
