If removed, install the crankshaft sprocket drive
pin (1). Lightly tap the pin in place with a small soft
face, bronze/plastic, hammer until it bottoms in the
hole.

Figure 6A1 – 432

CAUTION

Ensure the crankshaft position sensor has
been removed from the cylinder block prior
to loading the crankshaft, as damage to the
sensor may occur.

2

Apply a liberal amount of clean engine oil to the upper
and lower bearing surfaces.

3

Gently lower the crankshaft (1) into position in the
cylinder block (2).

Figure 6A1 – 433

4

Install the crankshaft main bearing caps.

5

Loosely install the original inner main cap bolts (1).

CAUTION

The outer crankshaft bearing cap bolts (2)
are yield tightened during assembly and
must be replaced prior to reassembly. Outer
crankshaft bearing cap bolts that are not
replaced will not torque to the correct clamp
load and can lead to serious engine damage.

6

Loosely install the new outer main bearing cap
bolts (2).

7

Gently tap the crankshaft main bearing caps with a
soft-faced hammer to help seat the caps.

originally have a sealant on the flange of
the bolt head. New bolts must be used. If
new bolts are not used, oil can leak from
the crankcase past the bolts.
