Hello.
So, a while ago I replaced the cup'n'cone BB bearings in my 1988 Peugeot. I also got a new crank set and spindle. It's the crank/spindle that's causing me grief at the moment.
Below is a photo of the old spindle. As far as I can measure, it's 32.5 mm, 56 mm and 33 mm, giving a total length of 121.5 mm. I can find spindles of the correct length, but not with those exact dimensions. Has anyone encountered a spindle like this before? It has the numbers "8" and "21" and the letters "S" and "B" on it.
OLD SPINDLE
I'm kind of asking this question too late - I'd already bought a spindle (assuming that all 121.5 mm spindles would be the same) only to find that they're not. But, since the bearing is adjustable, maybe this isn't too much of an issue as long as my chain line is okay... ?
But there is a much more... *ahem* pressing issue - the press fit between the new crank and the spindle. In the following photographs you can see that the old crank sits much farther in (4.5 mm) on the spindle that the new crank (on both spindles). And the old crank sits too far in on the new spindle.
OLD SPINDLE NEW CRANK
OLD SPINDLE OLD CRANK
This would indicate that:
Both old crank and old spindle were JIS,
The new spindle is also JIS,
The new cranks are ISO.
Now I've read on Sheldon Brown and various forums that one can mix 'n' match between standards with no problems, but I'm having problems here. When I go to tighten the nut on the end of the spindle I strip the threads instantly. I think this is because the threaded boss doesn't protrude enough from the spindle for the nut to get enough purchase (because the crank sits too far out on the spindle).
So I think I need to get a new spindle. But, it's hard to find spindles 121.5 mm long, it's impossible to find spindles that are divided into the dimensions I mentioned above, and the sellers on the likes of Ebay NEVER state weather it's JIS or ISO.
Before I spend any more cash, would anyone have any thoughts on the issues I'm having at the moment? Any input would be really appreciated - I'm itching to get this machine back on the road!
EDIT: I forgot to mention that the old cranks were made by Sachs Huret, and the new ones by Gipiemme.
