Somehow I cannot download the picture better go to bed and try again in the morning :-(
The purpose of locking the crank at TDC is to prevent the crank assembly from moving while releasing the cam drives. You should not be attempting this without the pin locking the crank at TDC as locking the cams will not stop the crank from rotating, even if it means temporarily putting the stock pulley back on the engine.
