damaged cranks?
poop.
continuation of this thread in which i told the saga of the mysterious creaking that everyone's had at some point(s). well, i'm starting a new chapter.
take a look here. after greasing the spindle and tightening the cranks as much as i could, the creak temporarily stopped. however, it came back on a longer ride, and now it's back in full force. i still think the spindle/crank interface, in some way, is the culprit, and i'm wondering if what's going on in these pictures would cause the creaking. see the pitting in the two pictures? i don't see pitting like that on the other cranks i have. could've been caused by torquing too much?
damaged, right? (and aren't my fingers quite petite?)

The grease/no grease question is bugging the hell out of me. My shimano 600 cranks started creeping up the spindle after I greased spindle during a rebuild last spring. Not just when I torqued the bolts, but riding as well (!?) Granted, they are very old cranks with a lot of miles, but they seemed to move farther/faster after I applied the grease.
They don't creak and there's no free play on the crank/spindle connection. The holes look good and square with no evident rounding etc. But still and all, they are pretty much all the way up the spindle, and that ain't right.
Jobst Brandt and others say grease on the spindle is no problem. Two local wrenches who I trust say absolutely no grease. What to do? I think I've been greasing 'em for years, and maybe that caused the problem?

so one more quick question (for now) before i'm off to buy a torque wrench:
is there any way to detect a different between JIS and ISO spindles by "eyeballing" or measuring? i'm not sure which taper my phil BB is the more confusing this gets.
thanks.

Try 107mm shimano BB now with that miche. JIS and ISO have same taper angles, but JIS is slightly larger. so worn taper of your miche might work fine with JIS now.

i think i might have to pop the bearings out to get to a serial number on the spindle.
these cranks are done. i don't think i want to try them with another BB. once i determine if the phil BB is ISO or JIS, i'll get cranks that are compatibile and go from there!

Interesting, apart from being bottomed out, the crank seems to be in decent condition.
As for the grease/no grease question, there's a really nice long thread here where the question is fully explored. The final answer in my book comes down to, there seem to be good reasons to grease and the only reason not to is, "that's what I've always been told."

honestly, i think i just torqued it too much with the grease on there. it wasn't the grease that caused the damage--it was me!--but i could get the cranks deeper on the spindle with it on there. i picked up a torque wrench yesterday and was surprised what 400 in-lbs felt like! less than i thought.
oh, and brent @ phil wood confirmed that my BB is in fact ISO. yay for fact!
