Looking for a crankshaft for my tecumseh. 3/4" keyed. I screwed up my threads on the flywheel side. My engine model number is hs40-55408c. Thanks IMG_20210527_153114130.jpg

What I have found helpful in nasty thread situation especially when the nut won’t start, is to gently bevel/point the end slightly….but will start right on and clean those threads

The nut goes on fine just slips when I get it snug

Well, I fixed it believer it or not. I used a rotary thread file in a Dremel and a hand thread file to finish it up. Took about an hour. Took my time and made sure it was right. Thanks for the input

The true test will be after you install the starter cup and nut and find out if it will hold when go to tighten it down. Tecumseh torque specs for the flywheel nut on your engine is 37.5 ft. lbs.
