Crank help please

(1/1)

Gary72:
Got a Sugino crank and it had a sealed bearing BB, But on the drive side where it threads on had disentegrated leaving the threads filled up.
What size would the threaded part be on the drive side? I guessing it's 24tpi, But what is the size and woukd it be in metric or imperial? I want to try and run a die over it and restore the threads if possible.
Cheers
Gary
