17.4 INSTALLATION OF CRANKSHAFT
Install the crankshaft using the following procedure:
EYE INJURY
To avoid injury from
fl
ying debris when using compressed
air, wear adequate eye protection (face shield or safety
goggles) and do not exceed 276 kPa (40 psi) air pressure.
1. Steam clean the crankshaft to remove the rust preventive and blow out the oil passages
with compressed air.
2. Install the upper main bearing shells in the block. If the old bearing shells are to be used
again, install them in the same locations from which they were removed.
NOTE:
When a new crankshaft is installed, ALL new main and connecting rod (upper and lower)
bearing shells and new thrust washers must also be installed.
3. Install the thrust washer upper halves in the counterbores on either side of the No. 6
bearing saddle. Coat the backs of the thrust washers (without oil grooves) with petroleum
jelly and install with the oil-grooved sides facing away from the saddle.
4. Apply clean engine oil 360 degrees around all crankshaft bearing journals and install
the crankshaft.
5. Install the lower main bearing shells in the main bearing caps as follows:
[a] Align the tang on the lower main bearing shell with the groove in the main bearing
cap. Install the bearing shell to the main bearing cap.
NOTE:
The main bearing caps are bored in position and stamped with position number. They
must be installed in their original positions, with the marked (numbered) side of each cap
toward the cooler side of the cylinder block.
[b] If the old bearing shells are to be used again, install them in the same bearing caps
from which they were removed.
6. Check main bearing cap bolt length.
