    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.
  3. Place the camshaft followers in position on the valve tip and stationary hydraulic lash adjuster (SHLA).
  4. The rounded head end of the follower goes on the SHLA while the flat end goes on the valve tip.
  5. Clean the camshaft journals and carriers with a clean, lint-free cloth.
