View Full Version : Conflict resolution needed
I am about to fit a Shimano BB to my Galaxy but the arrow
sticker on the bearing is 180 degree at variance with the
printed instructions.
The BB is a two part fitment the main body and a supporting
ring. According to the sticker the metal main part goes on
the opposite side to the chain ring whereas the written
instructions indicate that the metal main body is fitted at
the chain ring side of the BB.
What do I do?
The last BB was no help as it had two support rings, one for
each side.
Help!!!!!!

I would go by the sticker. Written instructions may be for
another model.....
"There are two different styles of Shimano® cartridge
bottom brackets. One type has a fixed flange on the
right side (drive side). The other type has a fixed
flange on the left side (non-drive side)."

What model is it? More instructions may be on the Shimano
websites. In any case, the parts won't screw in if they're
the wrong way round, would they?

The part attached to the bottom bracket goes on the drive
side and replaces the fixed cup.

I am assuming that the sticker points to the R and L,
facing the direction of travel with the sticker the right
way up does the R point the fixed metal support ? and is it
on the right ?

Well, anything's possible but is that likely? I don't think
so. Instructions (in general) frequently apply to something
totally different than what's in the box!

Just take the support ring and try to gently start it off on
both sides (trying turning both directions). One side it
will screw in, one side it won't because it has the wrong
handed thread. Once you know which side that goes, the rest
is obvious

This will only work if its is an English BB Shell which I
expect a Dawes is. The same thought came to me in the
bath just now - Eureka ! Italian BBs have right thread on
both sides.

Thanks chaps!
The BB is now fitted having discovered that:
1 the instructions were wrong 2 the sticker was right 3
italian threading would have resolved nothing 4 the
handedness of the shell sorted out the problem
If I'd done what I normally do, fit the item and several
weeks later, glance at the instructions, I would never have
had this problem!

They will if you really try hard.
Don't ask.
