to the roller pivot pocket (2) and valve slot areas (1) of the camshaft
followers.
Important: The follower must be positioned squarely
on the valve tip so that the full width of the roller will completely contact the
camshaft lobe. If the followers are being reused you must put them back in their original
location.
- Place the camshaft followers in position on the valve tip (1) and the
stationary hydraulic lash adjusters (SHLA) (1). The rounded head of the follower
goes on the SHLA, while the flat end goes on the valve tip.
