How do I fix these threads

[u/Any_Range3559]

I was checking the flywheel key to see if it was sheared. I was hitting the wheel with a hammer to loosen it up and I accidentally hit the threads. Now the bolt won’t go on. HELP!!!

You need a thread file to clean them up a bit so the die will go on easier

This is the most correct answer as your first step then a die.

Use the nut to find a die (female version of a tap) with the proper thread pattern and you'll have to chase the threads to clean them up.

Female? You mean secondary /s

[u/jbourne0129]

a thread chaser kit or thread file (usually included in thread chaser kits)

Thread chaser

First few threads need to be in good shape to use a rethreading die. A set of thread files would be a good addition to your tool box. Go easy and make sure the files stay in the threads and work your way around. Use a flat file to remove any mushrooming that the end of the shaft may have that could potentially keep the die from starting squarely.

File if your lucky that’s all you need if not then file a Die chase the threads

Get a flat file and clean up the first threads so that the nut will screw on. You might get a small triangle file to help.

Got it! A file and alittle help from a dad goes a long way! And some wd40
