NOTE: When Installing new packing, use a blunt punch
with a diameter slightly smaller than the packing groove.
Punch end should be not shorter than 4 inches to insure
seal bottoming.
Packing must be compressed until it bottoms in the packing
grooves, and enough packing Installed to make a solid
seal flush with front face and bottom face of the bearing
caps.

3. Install upper and lower bearing shells. CAUTION: Do
not file bearing shells or bearing caps.
4. Tighten all bearing cap bolts to 70-80 foot pounds with
J-1264 torsion wrench.
After Installation of new bearing shells, check crankshaft
end play which should be .003 minimum to .009
maximum.
5. Install wick packing into the vertical holes (1) and (2) in
front and rear caps first, Figure 16, then into the horizontal
holes (3) of the front bearing cap, Figure 17.

NOTE: To determine shell thickness proceed as follows:
1. Add the diametral clearance to the crankshaft diameter.
2. Subtract the total from the block bore diameter.
3. Divide the answer by two to determine the thickness of
the bearing shell
