Put the Number 5 main bearing cap in position for 12 cylinder engines. Put the Number 7 main bearing cap in position for 16 cylinder engines. The cylinder number is on the bottom of the main bearing cap. Ensure that the number is facing toward the front of the cylinder block. Note: Ensure that the main bearing caps are installed in the original positions. Ensure that the numbers that are stamped on the main bearing caps and the numbers that are on the left side of the oil pan are identical.
Use Tooling (D) to raise main bearing cap (6) on the studs. The weight of each main bearing cap (6) is approximately 65 kg (145 lb).

Tighten the collars by using a 1/2 inch ratchet. After the nuts are tight, the nuts should be loosened 1/4 turn.
Attach Tooling (B) to Tooling (A).
Before you operate the pump, ensure that all connections are secure. Ensure that all hoses are in good condition. Oil escaping under high pressure can cause personal injury.
Note: The stud tensioner tool groups in Tooling (A) require different operating pressure.
Run the pump in Tooling (B) until the operating pressure is registered on the gauge. This will put tension on the studs.
Use dowel handle (11) to tighten each nut. The nut should turn 5 to 8 holes. If the nut turns more than eight holes or less than
