The Chrysler 440 cubic-inch, V-8 engine was produced from 1967 to 1978 and was the largest V-8 engine produced by Chrysler. The 440 uses non-adjustable rocker arms mounted on a shaft that bolts to the cylinder heads. Installing the rocker arm shafts is a fairly straightforward operation. However, proper positioning of the shaft is crucial to sufficient rocker arm and valve lubrication because of the need for proper alignment of the oiling holes on the bottom of the shaft.
Instructions
- 1
Remove the end bolt and retainer from the rocker shaft. Remove the first rocker arm. Look at the underside of the shaft for the small oil hole in the shaft. It is offset 15 degrees from the mounting bolt hole. Orient the shaft so that the small hole is on the valve side of the shaft when mounted. Replace the rocker arm, retainer and bolt.
2Mount the rocker shaft on the cylinder head and start the five mounting bolts by hand. While threading the bolts, position the push rods in the ends of the rocker arms.
3Use a ratchet and socket to finish threading the mounting bolts, a little at a time, starting with the center bolt. Move to the bolt to the right of center, left of center, extreme right, and extreme left.
4Use a torque wrench to torque the bolts to 25 foot-pounds, following the same pattern.
5Follow these steps for the other shaft.
