Installation
CAUTION
If the crankshaft is going to be installed with the rods in
place, make sure the 12 crankcase protectors are
installed to protect the crankcase and the aiming of the
piston nozzle squirt tubes. A small alignment error of the
piston nozzle squirt tube may cause severe damage to
engine.
NOTE
The crankshaft may be installed with all 12 connecting
rods in place on the crankshaft. The connecting rods are
installed on the crankshaft in pairs. The connecting rod
of each pair toward the flywheel end (rear) serves the left
bank cylinders; the connecting rod toward the front of the
engine serves the right bank.
1. Install seven upper main bearing halves (27) in accordance with their respective location marks, making sure the
main thrust sleeve bearing half goes in No. 4 web.
2. Coat upper main bearing halves (27) with lubricant (item 14, WP 0100 00).
