Installed missing case half alignment pin. The pin was a tight fit so I placed the 8 mm x 25 mm steel pin in the deep freezer for 48 hours and then used a heat gun to bring the pin bore in the engine case up to ~250*F. I then immediately placed the pin in to the engine case. After tapping it gently with a ball peen hammer, there was still roughly 2/3 of the pin protruding out. I used a black sharpie and transferred the stick out dimension of the stock case pin on to the new one. I settled on an angle grinder to cut down to the marked dimension and then used files to remove the burrs and add a slight taper (as seen on the stock pin). I finished up by wrapping the pin with 220 grit sandpaper and sanding everything smooth.
