11. Tighten the bearing cap bolts (1a) using a
suitable angle tightening tool (1b) to the proper
(Torque Specifications).
12. Verify that the main bearing journal diameters
are within specification (Refer to 09 - Engine/
Specifications).
13. Check that the lubrication channels in the
crankshaft are free of debris and clogging.
14. Measure the crankshaft main bearing journal
diameters and verify that they are within
specification (Refer to 09 - Engine/Specifications).
15. If the crankshaft main bearing journal
diameters do not fall within the specifications,
correct by refinishing the diameter of the journal up
to an additional 0.127 mm.
NOTE
Do not attempt to refinish a crankshaft main
bearing journal diameter more than 0.127 mm.
Diameter adjustments greater than this endanger
the structural strength of the crankshaft. If the
adjustment required is greater than 0.127 mm, it is
necessary to replace the crankshaft. The bearing
shells used for adjustments greater than 0.127 mm
are no longer available as a spare (although the
relative number is still shown).
16. Measure the crankshaft rod bearing journal
diameters and verify that they are within
specification (Refer to 09 - Engine/Specifications).
17. If the crankshaft rod bearing journal diameters
do not fall within the specifications, correct by
refinishing the diameter of the journal up to an
additional 0.127 mm.
NOTE
Do not attempt to refinish a crankshaft rod bearing
journal diameter more than 0.127 mm. Diameter
adjustments greater than this endanger the
structural strength of the crankshaft. If the
adjustment required is greater than 0.127 mm, it is
necessary to replace the crankshaft. The bearing
shells used for adjustments greater han 0.127 mm
are no longer available as a spare (although the
relative number is still shown).
18. Select main bearings to achieve the proper
bearing clearance. Do not attempt perform any
adaptation to the bearing shells. If you encounter
any scratches or traces of engagement, replace
the bearing shells with bearings from the same
scheduled class.
19. Verify the bearing shells are clean and install
them in the engine block crankshaft journals.
20. Install the crankshaft into place.
21. Apply the calibrated wire (Plastigage) across
the surface of the bearing journals (1).
22. Check one journal at a time without moving the
crankshaft.
NOTE
The main bearing caps have engraved notches
(zero to four from the front of the engine) which
define the mounting position.
