INSTALLATION
CAUTION
When a new or reground crankshaft is installed, all new main and connecting rod bearing
shells and thrust washers must be installed.
1.
Install upper main bearing shells (Figure 7, Item 10) in block. If bearings are being reused, install them in
same locations from which they were removed.
2.
Apply clean engine oil to upper bearing shells and completely around crankshaft main bearing journals.
WARNING
If hoist and sling are not available, use two or more personnel to remove crankshaft.
Crankshaft is heavy and awkward to handle. Serious injury can result if crankshaft is
dropped. Failure to comply may result in injury to personnel.
CAUTION
Do not damage journals or main bearing shells when lowering crankshaft into position.
Damage will result in short component life.
3.
Place crankshaft (Figure 7, Item 8) in upper bearing shells in cylinder block.
4.
Install upper crankshaft thrust washers (Figure 7, Item 9) on each side of rear main bearing support with
grooved side of thrust washers toward crankshaft thrust surfaces.
NOTE
Install bearings in same bearing caps from which removed.
All crankshaft bearing shells have a tang for proper alignment. Upper bearing
shells have oil holes for lubrication.
5.
Install lower main bearing shells (Figure 7, Item 11) in bearing caps (Figure 7, Item 2). Install two lower
thrust washers (Figure 7, Item 1) on rear main bearing cap with thrust washers over dowel pins in sides of
main bearing cap and grooved side of washer facing crankshaft thrust surface.
NOTE
Main bearing caps are bored in position and stamped 1, 2, 3, and 4. Install caps with
identification stamp on right side of engine.
6.
Install four main bearing caps (Figure 7, Item 2) along with lower bearing shells (Figure 7, Item 11) and
two lower thrust washers (Figure 7, Item 1). Lubricate bearings and thrust washers with engine oil prior
to installation.
