Can someone get me the part number for the Park Tool Bottom Bracket tool for a bottom brack on a Nishiki?

Thanks

Not unless you tell us what kind of bottom bracket you have! Pictures, if you don't know.

Nishiki used a lot of different bottom brackets over the years. A lot of Nishikis weren't even made by Nishiki, they were made by others. And vintage bb tend to need a tool for the fixed (drive) side, and a second tool for the adjustable side. So one tool might not be enough (depends on your bb). I use the HCW-4 a lot on the fixed cup side on vintage bikes. I occasionally use a HCW-11 for the adjustable side, sometimes I use a pin spanner, and sometimes the pin spanner end on the HCW-4 is good enough.

My favorite bb tool is one that was made by Sugino. Unfortunately, those tools are no longer in production. You still see them on ebay, they can go high.

Shoot...don't have access to a camera for while.....I shall figure it out then

It is a Japanese made Nishiki Olympique made between 1985-87, as of right now that is what I have

Japanese bikes of that vintage almost universally use the Park HWC-4 and a pin spanner, as above.

I still have my set with pouch! I used it the other day on a vintage. Except I can never get both spanner pins to engage, like the tool is slightly tweaked.

Ditto from me on all points. The pins on the spanner get a bit worn- sometimes you can turn them a bit to help them engage the holes on the adjusting cup.
