Yesterday I replaced the crank sensor on my 245. Now, I'm not an expert with 40+ years of wrenching experience, but I consider myself pretty mechanically adept. I've swapped transmissions & rebuilt engines, etc.

I'd read about how weak this bracket is, so I was careful when working on it and happy when I got the old sensor out without breaking anything. Before putting in the new sensor I put a little silicone lube on the outside of the barrel, cleaned up the threads on the bolt with a die and put antiseize on it before bolting it back.

Whelp, it broke as I tightened the bolt. Maybe I had it cross threaded. I was doing it all by feel, so who knows? It's in the car, and the car runs. Everything is snug, but I figure it's only a matter of time (or temperature) before it wiggles itself loose.

So now I'm on the hunt for one or two spare brackets, but I can't help wonder:
Why are these so flimsy?
Why isn't anyone making sturdier replacements?
Why not make them out of steel, will it interfere with the magnetic signal? If so, why not copper, or even just a thicker piece of aluminum?
