Crankshaft Final Installation Procedure 

1 

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 – 522 

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 – 523 

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.

8 

Loosely install new short / inner side main cap 
bolts (4). 

CAUTION

 

•  The short / inner side main cap bolts 

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. 

•  The long / outer side main cap bolts 

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. 

9 

Loosely install the new long / outer side main cap 
bolts (3). 

10 

Tighten the main caps bolts to the correct torque 
specification, and in the following sequence. 

„ Crankshaft main bearing cap inboard 
attaching bolt torque specification: 
 Stage 

1 .........................20.0 Nm 

 Stage 

2 .................................80° 

„ Crankshaft main bearing cap outboard 
attaching bolt torque specification: 
 Stage 

1 .........................15.0 Nm 

 Stage 

2 ...............................110° 

„  Crankshaft main bearing cap side 
attaching bolt torque specification: 
 Stage 

1 .........................30.0 Nm 

 Stage 

2 .................................60°
