Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: For installing valve bridges with a dowel refer to Step1 through Step 4. For Installing floating bridge assemblies refer to Step 5 through Step 6.

Loosen adjustment screw (7) and jam nut (8) on the bridge assembly.
Coat these items with clean engine oil: dowels (4), the receptacle of the bridge for the dowels and the uppermost contact surface of bridge assembly (3).
Place the bridge assembly into position on the dowel. Apply 1 to 14 N m (1 to 10 lb ft) of downward force on the uppermost contact surface of bridge assembly (3). While you apply the force, turn adjustment screw (7) until the screw contacts valve stem (9).Adjust screw an additional 20 to 30 degrees (1/3 to 1/2 of the hex) to straighten the dowel in the guide.Note: The bridges should be oriented so that the bridge marked “EX” is above the exhaust valves. The part numbers on the bridges should face the front of the engine.
Hold the adjustment screw in position and tighten jam nut (8) to a torque of 30 4 N m (22 3 lb ft).

Apply clean engine oil to the contact surface of bridge assemblies (3) and the valve stems. Install bridge assemblies (3) on the valve stems.
Install the bridge assemblies with the round pocket toward the outside of the engine. Refer to Illustration 2.Note: Installing each pushrod in the original location is critical.
Coat pushrods (5) and the cups of the valve lifters (6) with clean engine oil. Place the pushrods into position on the valve lifters.
Ensure that the crankshaft and the camshafts are in time with each other. Also ensure that the adjustment screws in the rocker arms are loosened completely before the bolts on the rocker shaft are tightened or damage to the valves and the pistons may occur.

If the rocker shaft is not positioned correctly, the oil supply to the sleeve bearings in the rocker arm will be shut off. This will cause seizure of the bearings and severe damage to the engine.Be sure to orient the rocker shaft in the correct position.
Place rocker shaft assembly (2) in position on the rocker arm base. Make sure that rocker arms (10) and pushrods (5) are aligned. Install bolts (1). If bolt (1) is a 5/8 inch bolt, tighten to a torque of 215 40 N m (159 30 lb ft). If bolt (1) is a 1/2 inch bolt, tighten to a torque of 120 20 N m (88 15 lb ft).
Adjust the valve bridge and the valve lash according to Testing and Adjusting, "Valve Lash and Valve Bridge Adjustment".
Adjust the fuel injection pump according to Testing and Adjusting, "Fuel Injector Adjustment".Tighten nuts (12) to a torque of 70 15 N m (52 11 lb ft).
Tighten nut (11) for the rocker arm of the fuel injection pump. If nut (11) is 5/8 inch thread, tighten to a torque of 120 15 N m (89 11 lb ft). If nut (11) is 1/2 inch thread, tighten to a torque of 70 15 N m (52 11 lb ft).End By:
Install the valve covers. Refer to Disassembly and Assembly, "Valve Cover - Remove and Install".
