This is the se cam bearing installer. I soaked the cam bearings in syn 3 first. The plate is held with fasteners that thread into the timing cover fastener bolt holes. When you install the bearings, the thicker side (side with the letters and numbers) is the side that the installer tool pressed against. So the thicker side of the bearings face outward once installed. Once the installer is set up, you torque it to 25 ft lbs, and the bearings are installed. I used a depth gage to double check.
