Installation

1. Install the crankshaft bearings into the engine block and into the bearing caps. Use the following procedure:
a. Coat the crankshaft bearings with oil.
b. Insert the plain, unnotched end between the crankshaft and the indented or notched side of the block. Rotate the beefing into place. Use the Main Bearing Shell Remover. Remove the Main Bearing Shell Remover from the hole in the crankshaft journal.

CAUTION: The #4 (rear) main bearing cap must be installed flush with the torque converter bolt heads or 0.25 mm (0.010 inches) forward of the rear face of the cylinder block to avoid interference with the flywheel.

2. Use sealer GM P/N 1052942 or equivalent at the number four bearing cap to the engine block surface.
3. Install the crankshaft bearing caps with the assembled crankshaft bearings inside and with the arrows pointing to the front of the engine.
4. Install the crankshaft bearing cap bolts. With the crankshaft, crankshaft bearings and bearing caps installed and the bolts started, thrust the crankshaft rearward in order to set and align the bearing caps. Then force the crankshaft forward to align the crankshaft thrust bearing.
^ Tighten the crankshaft beefing cap bolts to 40 Nm (30 ft. lbs.). Use the Torque Angle Meter in order to rotate the bolts an additional 35 degrees + 35 degrees + 40 degrees for a total of 110 degrees.
^ Tighten the crankshaft bearing cap side bolts to 15 Nm (11 ft. lbs.). Use the Torque Angle Meter in order to rotate the bolt an additional 45 degrees.
5. Measure the crankshaft end play. Use a dial indicator or a feeler gauge. If you are using a feeler gauge, measure between the front of the bearing cap and the crankshaft thrust surface.
6. Install the oil pump screen.
7. Install the oil pan.





8. Install the spark plugs.
