Shimano 7 speed cassette assembly(4 posts)

Shimano 7 speed cassette assemblydan ida

I am putting together a cassette from a box of loose gears. I notice that there three positions that each gear can go on, in relation to the others behind it. Which position is correct? Two teeth on each gear are shorter than the rest. Are they part of the puzzle? THANKS

They're different and from your description I'm betting you have a spin-on freewheel because cassette cogs will only go on one way.

I think that when you get it right, the short teeth will form a sort of spiral around the freewheel. Good luck.

This is an older uniglide cassette. The sprockets can be put on in any one of three spots, there is no larger spline like on hyperglide. Looking at it again, I see the spiral you are talking about. But does it go clockwise away from the large gear or counter clockwise away from the large gear. A few of the smaller cogs do not have smaller teeth at all. Are they cheaper "generic" replacements, or is that OK?

THANKS DAN

Don't know about that exact cassette, but the newer stuff I've got laying around all have the spiral running clockwise from the big cog. For what it's worth, the odd-shaped teeth on the smaller cogs aren't as pronounced as on the bigger ones. I'd use the cogs you have and see how it works. I'm betting it shifts fine.
