Why Replace Your Cam Sprocket Bolt?
Mechanic’s Note: The camshaft sprocket bolt is subject to constant engine vibrations. Reusing a stretched, rusted, or rounded bolt risks timing failure, which can lead to catastrophic piston-to-valve damage. Always upgrade or replace yours during head maintenance to keep your engine running smoothly and safely!
Installation Reminder
-
Clean the internal threads of the camshaft before installation.
-
It is highly recommended to apply a drop of medium-strength thread locker (e.g., Loctite 242) and torque to the manufacturer’s exact specifications to prevent any loosening over time.
