After three days of soaking, heating, freezing and sheer brute force having no impact on a seized crankbolt I sadly had to get the Dremel out and thirty minutes of interpreting flying sparks as flying pound signs I finally freed the cranks and part of the axle from the frame.
One Gnutti cotterless crank and axle down now
So it had me wondering just how many of you had similarly sad but necessary tales?
Please share and ease my guilt

Well, it was just 3-4 weeks I had the most troublesome cranks to remember.
They had to go anyway, so when the (Park) crank puller had stripped the thread, the typical swearing came.
Was surprised to see the whole thread for the puller coming out like a sleeve, all of a sudden. Weird :roll:
Cranks and b.b. had to go, so resorted to the 2-arm big puller, to no avail.
Whaaaat??? :?
Then big wedge +hammer.
Nothing :shock:
Fine, cut the b.b. axle; removed all the old crap and installed the new parts. All ok, bike serviced, nicely working now with new drivetrain.
But wanted to remove the stub of b.b. axle from that Lh crank!
So, bearing drift (ground steel) with 20mm ID under the crank, workshop assistant holding the crank, bolt fully threaded in the stub, hit with biggest hammer.
Nothing :x
Then same system, but heating-up the crank with flame, while cooling the axle stub with the air gun (from its hole), the quickly threaded a new bolt in the stub and put the crank in the 8" vice, two blokes tightening as hard as they will go.
Nothing! :evil:
Left it there, it was just for price but... it won! :twisted:
