1974 Schwinn Sports Tourer crankset

My dad has a 1974 Sports Tourer and the left crank came loose and now it can't be tightened and he wants a replacement. My question is what crankset should I be looking for?

He doesn't do the internet or cell phone otherwise I could look at pictures. The online catalog doesn't list what crank it came with or at least I didn't see it.

Any help would be appreciated.

The Sports Tourers were specced with various cranks depending on the year and how good supply was for the OEM. Nervar Star or TA "Schwinn Approved" (Cyclotouriste with extra chain guides/guards designed by Schwinn to aid shifting). I believe when TA had trouble keeping up with demand during the bike boom Schwinn started speccing Nervar to make up the deficit.

While not OEM, I believe the 3-arm TA Professional crankset was a relatively popular upgrade option for Sports Tourers at the Schwinn shops. I have seen a few Sports Tourers with this crank, including my own.

@Metacortex has lots of detailed knowledge on when different components were specced on these bikes.

Thanks for the info. If I can find any of those I think he'll be happy. He has a thing about keeping stuff original so as long as it was a possibility it should be okay.

By '74, IIRC, it should be a Nervar that looks mostly like this one. I've polished mine and added a granny gear for hill climbing.

Found this post from Metacortex from a couple years ago:

From 1971 through 1974 both cranksets were used interchangeably but for 1975 (final year for the Sports Tourer) only the Nervar crankset was used. In 1976 the Superior replaced the Sports Tourer and also used only Nervar cranksets until it was discontinued in '78.

Two words of warning:
1. Make sure the bottom bracket spindle taper is not damaged before installing a new crank. If the old crank doesn't stay tight the bottom bracket spindle might need replacing as well.

2. When shopping for Nervar cranks be aware of the threading. The cranks used on these Schwinns had English threads for the pedals, but if you buy a Nervar or TA crank made for the French market it might have French pedal threads. Which can be tapped to English but best to be aware.

Thanks for all the info guys. There is a bike swap meet this weekend and I will look there first, but if not Ebay it is.

If you find it hard to find an exact replacement, virtually any left crank will do. Just make sure the length is right, probably 170mm.

You are right about the 170 mm crank arms.

He's kind of picky about keeping stuff original. Otherwise I have a nice crankset off a Nishiki International (badly dinged downtube) I could send him.

While in theory I like keeping bikes like that original all my bikes are changed from factory spec. The only bike I have that might be a considered a classic though is a 72 Fuji Finest.

He has a Sports Tourer and a Touring Paramount.

I don't have any sorry.

I remember riding the Paramount in High School. Red, foam on the handlebars instead of tape and bar end shifters.

I know in late 80's my brother was riding the Paramount a lot all over far Northern California.

He had to send it back to the factory to be repaired and painted since he cracked/broke a weld on the bottom bracket. He also had water bottle mounts put on at the time. Bought fancy set of tubulars and everything.
