REPAIR INSTRUCTIONS, PART 1
ENGINE REASSEMBLY
General Instructions
This section includes step-by-step procedures for
complete reassembly of the engine. Major
components that were inspected and overhauled
or replaced under the respective bench
procedure sections of this manual are reinstalled
here as assemblies.
Failure to follow the sequence of operations listed
may result in damage to components or personal
injury.
After cleaning the components, properly store
them where they will remain clean until needed
for reassembly.
When required for installing components, be sure
to use clean engine oil of the approved type.
Crankshaft Installation
[212 HP]
1. Be sure that the crankshaft and the
crankcase area of the cylinder block are
clean.
2. Thoroughly clean each main bearing bore
and the back of each bearing insert before
installation. The inserts must be installed
dry.
The hole in the insert must line up with the drilled
hole in the block or the bearing will fail due to lack
of lubrication. The upper bearing insert is
stamped on the back with the word “UPPER.”
3. Place the upper half of the bearing insert in
the cylinder block main bearing bore,
making sure that the locating tab fits into the
notch in the bore (Figure 321).

bearing insert.
