Frequently Asked Questions
Where do these parts fit an A-Series engine?
Our range of A-Series performance camshafts are gun drilled through the centre in order to supply the lobes with lubrication, also known as cross-drilled. This grub screw blocks the end of the cam to allow this to work. The keyway secures the cam pulley/sprocket in place.
Do I always need to change these?
Usually only if you have lost them, although the cam keyway can sometimes wear. These are supplied with our brand new cams.
What size is the grub screw?
These are 1/8" BSPT, with a 3/16" hex fitting.
