Bottom bracket on a '97 Klein - pressed in???(5 posts)

Bottom bracket on a '97 Klein - pressed in???OffTheBack
Aug 3, 2002 4:26 AM
Iv'e taken apart my '97 (or maybe '96) Klein quantum (gonna sell it), and I can't figure out the BB. It has no lockrings on either side, and I don't see anyplace to put a pin wrench or a spline tool. Anyone know how this thing is held in? Is there a snap ring or something that I didn't see? It has cartridge bearings and a square-taper spindle.

I'd appreciate any clues. Thanks!

but some Kleins have proprietory headsets and bottom brackets. I don't personally think they are among Gary Klein's better ideas.

On the upside, if you email Klein, you will get a response. Often you'll get an answer from Gary himself.

It's pressed in and requires special tools to put in and remove. You need to go to a Klein dealer or buy $500 of tools to remove it. That's the exact reason I sold both of my Kleins. The new ones have thread in bottom brackets although Klein's weld finishing isn't what it used to be.
Thanks for the info! (nm)OffTheBack

I thought they stopped doing that stunt well before '97 and that one should simply be looking at a standard Shimano spline BB tool for removal. A quick check with the standard BB tool should verify, plus you should be looking at the side of a fairly massive precision bearing and it's seal. If it really is the pressed in sealed bearing deal then one might ask why you want to remove it? The whole works is pretty bomb-proof. In any event you can pop the whole works oout without too much trouble with a standard press found in any modest machine/automotive/hobbiest shop. The trick is being careful enough to properly support the BB shell - don't let just any ape work on it. A Klein dealer would have the fixtures.
