INSTALLATION
NOTE: Be sure that the oil hole in the main bearing
lines up with the oil gallery hole in the cylinder block.
(1) Using the VM.1002 push the front main bear-
ing into the cylinder block (Fig. 111).
(2) Fit the main bearing supports together. Torque
to 44 N·m (32 ft. lbs.)
(3) Check internal diameter of bearings.
(4) If internal diameter of original bearing is being
checked and figures are not within specifications,
new bearings must be used.
(5) Check the crankshaft main bearing journals to
bearing clearances. Clearances of main bearings is
.03 to .088mm (.0011 to .0035 in.).
NOTE: Assemble engine according to sequence
described, thus saving time and preventing dam-
ages to engine components. Clean parts with a suit-
able solvent and dry them with compressed air
before assembly. Use new gaskets where applicable
and torque wrenches for correct tightening of com-
ponents.
(6) Thoroughly clean crankcase and oil passages,
and blow dry with compressed air.
(7) Install new main bearing shells in each of the
carrier halves. Assemble the carriers to the crank-
shaft journals, ensuring that the carriers are
installed in their original locations. Secure each car-
rier with the two bolts tightening evenly to 44 N·m
(32 ft. lbs.).
