In these photos show how the scavenge pump lines up with the cam. Your cams would need this piece to be welded onto them with the holes so you could turn the pump.
Or you could purchase a pair of 930 cams and have them ground to SC specs which would require you to have them hard welded. WebCams recently did mine but for what you are doing it would be much less expensive to have your SC cams fitted with that end cap.

Best of luck,


The sequence goes Cam, Paper gasket, Cover for air pump, pulley (holds on the cover and also turns the scavenge pump with the heads of the allen bolts), cover plate, and finally the pump.

This was before I rebuilt the motor and the pulley had been damaged early in the lfe of the car. Since I have purchased 2 new pulleys and it looks great.

After the rebuild on reasembly. You can see how the parts would go together.
