I can't just remove the gear and leave the shaft?
Also zzp doesn't say anything on their website about machining the roller which is why I'm lost here.
To run the *double roller, the balance shaft gear must be removed. To save additional weight the balance shaft can removed altogether but this requires plugging the rear oiling hole. The Rollmaster has a much tighter fit, so the timing chain tensioner is no longer used. Since this chain is larger, we recommend swapping your oil pump cover for our Machined version, and run our Extra Thick Front Cover Gasket.
Double chain sets are recommended for engines running aftermarket valve springs.
*Due to potential front cover clearance issues on some cars, we recommend running our thicker front cover gasket and our machined oil pump cover when installing the double roller.
The Cam position sensor magnet pushes in from the backside in the hole that is recessed.
