If im not mistaken the crank sensor gear is the flywheel. Try hmaservice.com they might be able to help, but doubt it. If your having problems with that sensor, its probly your sensor. Or yur starter is searing off some of your teeth on your fly wheel.
I've read elsewhere that it may be 58 teeth or 60-2. When I remove the sensor and try and count myself I get something like 50 or so but I may be missing some. It's quite difficult to turn the motor over by hand and watch down the little dark hole.
