I have SRAM S2200 (X.0) cranks with a BB30/PF30 spindle. They are 3-piece ones, with the self-extracting mechanism on the right (drive) side, and a regular non-puller bolt on the left side.
I want to replace the spindle, because I stripped the thread on the original one. However, I had no luck taking the left crankarm off it. The lobed interface between the arm and spindle is fused tight.
Attempts so far:
- WD-40 won't get in there (or has no effect)
- I haven't found a safe way to heat up the crankarm to loosen the join (crankarm is carbon = not a good idea)
- I can't use the self-extracting mechanism from the right side (because there is no thread for the top cap, see pic).
- Hammering on the tightening nut (while it is loosened and slightly protruding above the crank) doesn't seem to do the trick, at some point the hammer just starts to damage the nut itself.
I found a thread on MTBR where somebody accomplished it, but the author hasn't described how (in much detail).
Any ideas on how to take this thing apart?
P.S. The photos might be misleading, so I'll re-emphasize: i only need to take the left crankarm off the spindle, i.e. the one which doesn't have the self-extracting mechanism. The right crankarm I have no issues with.
