CYLINDER HEAD TORQUE AND SEQUENCE






CAUTION: Cylinder head bolts are coated, DO NOT oil bolts.

Install cylinder head(s) over dowel pins. Install new cylinder head bolts 1-12. Tighten cylinder head bolts 1-12 in the sequence shown in using a three step tightening sequence:

a. First to 35 Nm (26 ft.lbs)

b. Second to 48 Nm (35 ft.lbs)

c. Third rotate an additional 90°

INTAKE MANIFOLD TORQUE AND SEQUENCE






Tighten bolts to 12 Nm (106 in. lbs.) as shown.

MAIN BEARING CAP TORQUE AND SEQUENCE






1. Install each main bearing cap in proper sequence and direction. Tighten all bolts finger tight.
2. Tighten main bearing cap bolts 1-12 in the sequence shown to 20 Nm (15 ft. lbs.).
3. To ensure correct thrust bearing alignment move crankshaft all the way to the rear of its travel.
4. Then, move crankshaft all the way to the front of its travel. Wedge an appropriate tool between the rear of the cylinder block and rear crankshaft counterweight to hold the crankshaft in its forward position.
5. Tighten main bearing cap bolts 1-12 to 61 Nm (45 ft. lbs.) in the sequence shown.
6. Tighten main bearing cap bolts 1-12 to 115 Nm (85 ft. lbs.) in the sequence shown.






7. Tighten main bearing cap side bolts 1-12 to 27 Nm (20 ft. lbs.) in the sequence shown.
8. Tighten main bearing cap side bolts 1-12 to 54 Nm (40 ft. lbs.) in the sequence shown.

ROD BEARING CAP TORQUE






CAUTION: Verify correct rod installation or engine damage could result. The large cut out (1) in the rod must face the crankshaft. The small cut out (2) must face the other rod.

1. Position rod cap in place and install connecting rod bolts. Bolt threads should be clean and free of engine oil.
2. Tighten connecting rod bolts to 45 Nm (33 ft. lbs.). Rotate an additional 45°.

HARMONIC BALANCER TORQUE

NOTE: Lubricate the threads of Crankshaft Damper Installer 9943 (2) using Mopar(R) Nickel Anti-seize Compound or equivalent, before beginning crankshaft damper installation.

1. Install crankshaft damper (1) using Crankshaft Damper Installer 9943 (2).
2. Install and tighten damper bolt to 176 Nm (130 ft. lbs.).
3. Install the crankshaft pulley. Tighten crankshaft pulley bolts to 23 Nm (200 in. lbs.).

FLYWHEEL TORQUE AND SEQUENCE






Tighten flywheel (1) bolts in sequence to 75 Nm (55 ft. lbs.).

OIL PUMP COVER TORQUE

Oil pump cover 23 Nm (200 In. Lbs.)

EXHAUST MANIFOLD TORQUE






NOTE: Care must be taken to protect the cylinder head covers powder coating from scrapes and abrasions.

Install new gasket (1) and install exhaust manifold (4). Tighten attaching fasteners to 29 Nm (257 in. lbs.).

WATER PUMP TORQUE AND SEQUENCE






1. Tighten water pump bolts in the sequence 11 Nm (95 in. lbs.).
2. Rotate the water pump by hand to check for freedom of movement.
