Does anyone know the thread pitch size and size die I should get to fix the threads on the end of my crank shaft? I think the thread pitch is about 1.5 mm and the diameter of the crank nose is about 13/16” (20.6 mm) but idk what for size to buy.
Lol yes thank you. That is a whole other can of worms. I have a new harmonic balancer, a new key, and am going to attempt the Loctite 660 for the key/keyway. If that does not work, I am looking into getting it welded.looks like your keyway is worn also.
When I had my crank out I had it cut 180 out but not by me. Unfortunately the crank is not a piece that can be easily removed in situ, cam yes, (I did it). But a dremel is nice tool. Years ago the cutting of a new keyway was suggested by using cold chiseles. I have an old Dremel that only goes one speed and I use it for all sorts of stuff. The little metal wheels are great and I recently bought the carbide bits which are the bomb!even after cleaning up the threads, there may not be enough left to hold torque
there was a thread years ago about cutting a new keyway 180 degrees off of the original, maybe using a dremel??
no idea on size of threads or pitch.
yeah I feel the same. As I’ve said before that 660 really doesn’t do what I felt it could have. It’s really hard to get into the sheared area to sand so it will have a better grip... At least add JB Weld to the open gap if you can’t weld.. I think you said you don’t. Let the JB set up for a few hours so it goes on thick and doesn’t wash out of the space your filling.Just weld the key in. You only want to put that back together once.
