Bolting on the degree wheel is your first step. Since you will most likely be adjusting the cam timing (and/or replacing the timing chain and gears to do so) the timing chain cover and front engine dress is removed for access. This engine, being on a dyno, meant just the damper, timing cover, and water pump had to be extricated. If you're doing this in the car during a cam swap, you may need to remove other accessories for degree wheel clearance. Don't wrench down on the crank bolt just yet, as you'll be adjusting the degree wheel in a minute.
