[QUOTE="Bunya, post: 1192653, member: 77196"] Does the flywheel nut spin on freely? It really sounds like the pitch is different on the crank. Both 1.5 and 1.25 are considered 'fine' for a 12 mm shaft so it's possible the crank might be 1.5. If the flywheel nut spins freely on the crank, it would indicate that the crank threads are in good condition. If that's the case then they're likely 2 different pitches. If you need it, the die is commonly available: [URL=http://www.jlindustrial.com/endeca/searchResults.jsp?_dyncharset=ASCII&ns=1&Ntt=12+x+1.25+die&Ntk=Keyword+Search]12 x 1.25 Die[/URL] Incidently, for chasing existing threads, the [I]Carbon[/i] steel hex die is fine but not for cutting new threads. For new threads you have to use the [i]HSS[/i] (high speed steel) die. A word of caution! Before I'd go putting a die on the crank I'd triple check the thread size to be sure it's the same. If you run a die down the crank and it's different, the crank will be junk. You could buy quite a few used flywheel weights for the cost of a crank! Marc - [/QUOTE]
