Improper assembly of parts that are spring loaded can cause bodily injury.To prevent possible injury, follow the established assembly procedure and wear protective equipment.
Apply clean engine oil to the stem of exhaust valves (6). Install the exhaust valve into exhaust valve guide (9).
Install inner valve spring (3) and outer valve spring (4) on exhaust valve guide (9).
Position valve rotator (2) on the stem of the exhaust valve.
Use Tooling (A) to compress inner valve spring (3) and outer valve spring (4). Install valve spring keepers (1) on the exhaust valve.
The valve spring keepers can be thrown from the valve when the valve spring compressor is released. Ensure that the valve spring keepers are properly installed on the valve stem. To help prevent personal injury, keep away from the front of the valve spring keepers and valve springs during the installation of the valves.
Carefully remove Tooling (A). Strike the top of the valves with a soft faced hammer in order to ensure that valve spring keepers (1) are properly installed on the valve stems.
