The new CPS arrived yesterday from Amazon. I installed it this morning. The engine fired right up and ran like it should.
I was a little surprised at what happened. The plastic center section of the CPS had partially broken away allowing the magnet inside to fall out. (photos below) That explains why I lost both, 3X and 18X CPS signals at the same time. The magnet had stuck to the shutter ring but didn't damage it. I was lucky.
I used my battery powered impact wrench to remove the crankshaft bolt. It had to hammer a while to break it loose. I put the bolt back in with blue Loctite and let the impact wrench hammer to get it tight. No, it's not up to spec but I don't think it will come loose.
