(1) Use a center punch to push the piston cooling
nozzle into place. Install nozzles so they are even
with or slightly below the saddle surface.
(2) Make sure the saddle surface is clean and dry.
Install the upper main bearings.
(3) Install the combination thrust/main bearing in
the number six main bearing location.
(4) Lubricate the bearings with Lubriplate 105, or
equivalent.
WARNING: T O AVOID INJURY, U S E A HOIST TO IN­
S T A L L T H E C R A N K S H A F T .
(5) Install the crankshaft.
