Valve Springs - Installation

INSTALLATION

Special Tools:










1. Install the valve seal.
2. Install the valve spring.
3. Using the valve spring compressor (1), compress the valve spring and install the valve spring retainer and locks.
4. Remove the exhaust extension arm (1).





5. Remove the spring compressor (3).
6. Remove the air hose from the spark plug hole.

NOTE: All valve springs and seals are installed in the same manner.







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).






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 longer pushrods are for the exhaust side and the shorter pushrods are for the intake side.

NOTE: Pushrods must be installed in the same order as removed.
