Nishiki
Greetings all. Recently I acquired An 70's Nishiki 10 so bike. I have restored most of it,but am having problems with the crank assembly. This bike has a weird bolt that connects the pedal arm to the crank shaft. The bolt a vertical flat on one side and threaded on the opposite side. I can't find this type bolt anywhere. Anyone come across this type crank ?? Thanks

Do the bolts look like this?
And the crank arms like this?
If so, you have what are known as cottered cranks. And the bolts are known as crank cotters. And you should refer to this.

Your post reads as though you have a Custom Sport or an early Olympic, which would indeed have cottered cranks. See the response above and follow the links on care and feeding of cotters, which were very common -- even on higher-end bikes -- at one time, but which are rarely seen today.
