Gav,
When you take out the CAS, there is a mark on the shaft of the CAS and another mark on the gear that meshes with the exhaust cam.
Line the two marks up with each other, have them pointing directly up, and install. Actually, its hard to fuck it up once you have the two marks lined up, cos there is only one way to install the CAS.
Basically the same method as installing a 4AGE dissy.
