Valve Lifter Installation

VALVE LIFTER INSTALLATION

NOTICE: If the valve lifters and anti-rotation brackets are not installed properly, the valve lifters, the anti-rotation brackets, and the engine could be damaged.

IMPORTANT: When installing new valve lifters, coat the lifters with camshaft assembly lube (GM P/N 1052365) or equivalent.





1. Install the valve lifters in the lifter bores.
^ Align the flat sides (top) of the lifters with the flat sides of the anti-rotation brackets.
^ When properly aligned, the flat side of each lifter is aligned parallel to the anti-rotation bracket.
^ The roller at the bottom of each lifter is aligned parallel to the camshaft lobe.





2. Install the anti-rotation brackets on the valve lifters.

NOTICE: Refer to Fastener Notice in Service Precautions.





3. Install the screws that retain the anti-rotation brackets.
^ Tighten the anti-rotation bracket screws to 11 Nm (97 inch lbs.).
