Rocker Arm, Valve: Installation
The longer pushrods are for the exhaust side and the shorter pushrods are for the intake side.
- Install the pushrods in the same order as removed.
- Install the pushrod retainer (special tool #9070, Retainer, Push Rod) (1).CAUTION:
Make sure that the retainers (1) and the rocker arms (2) are not overlapped when tightening bolts or engine damage could result.
CAUTION:Due to the changes in the pushrod clearance holes in the Eagle 5.7L cylinder heads, close attention must be given when installing the pushrod(s) into the tappet(s). Once the pushrod(s) have been installed, use a suitable light to look down through the pushrod hole(s). This will allow you to verify the pushrod(s) are centered properly in the tappet(s) and avoid engine damage. Recheck after the rocker shaft assembly has been installed and tightened to specification.
CAUTION:The rocker shaft assemblies are not interchangeable between the intake and the exhaust, failure to install them in the correct location could result in engine damage. The intake rocker arms (1) are marked with the letter "I" (2).
- Install the rocker shaft assemblies in the same order as removed.
- Using the sequence shown, tighten the rocker shaft bolts as follows:
- Snug to 10 N.m (7 ft. lbs.)
- Torque to 23 N.m (17 ft. lbs.)
- Individually loosen by 1/2 turn and re-torque to 23 N.m (17 ft. lbs.)
- Finally, Rotate 30 degrees
CAUTION:Do Not rotate or crank the engine during or immediately after rocker arm installation. Allow the hydraulic roller tappets adequate time to bleed down (about five minutes).
