1. Apply a liberal amount of lubricant GM P/N
12345501 (Canadian P/N 992704) or equivalent to
the pivot pocket (1), roller (2) and valve slot (3) areas
of the camshaft followers.
NOTE
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.
2. Place the camshaft followers in position on the valve
tip and stationary hydraulic lash adjuster (SHLA).
3. The rounded head end of the follower goes on the
SHLA while the flat end goes on the valve tip.
4. Clean the camshaft journals and carriers with a
clean, lint-free cloth.

1. Ensure that the crankshaft is in the stage one timing
drive assembly position using the EN 46111. Refer to
"Camshaft Timing Drive Chain Alignment Diagram
(Third Design)" "Camshaft Timing Drive Chain
Alignment Diagram (Fourth Design)".
2. Ensure that the camshaft sealing rings (1) are in
place in the camshaft grooves. Camshaft sealing
rings must be in place below the surface of the
camshaft journal in order to avoid being pinched
between the cylinder head and the camshaft caps.
