Ultra Torque crank removal. Cannot undo bolt!

othello

I'm stripping down my old winter frame and trying to remove the Campag Ultra Torque chainset and bb. First job is getting the cranks off...

I have the official UT bolt tool which I have put in via the drive side. I have a spanner on the tool and am trying to undo it (going anti-clockwise). But I just cannot move the bl**dy thing! I've leant on it, hit the spanner with a hammer etc. No joy.

Any tips?

Go clockwise....

But all the videos I've watched have the bolt unscrewing the 'normal way' i.e. anti-clockwise

Anticlockwise is correct. How long is your spanner? I use a big 18 inch long torque wrench to extract these bolts with the bike in a dropout mounted stand (ie the BB is supported by the stand itself) and even then it is sometimes an effort to free the bolt. You probably just need more leverage.

Not long enough by the sounds of it! I've got a 'normal' spanner and the frame in a clamped workstand.

I'll see if I can borrow a long arm torque wrench and give it a go.

A bit of pipe fitted over the spanner end should also do it. The torque wrench I got was a £15 one from Lidl. It is pretty good for BBs and cassettes though nothing much else on the bike. But for the money, that's enough!

If its a Super Record, it will be left hand thread. But I would guess you aint that rich to fit one to a winter bike

Pretty sure my Super Record was conventional RH thread, i.e. undo anti-clockwise

You shouldn't use torque wrenches to undo anything!

I ended up getting the guys in the LBS to undo the bolt in exchange for a bag of cookies

Was it just seized?

Yes. Just needed a socket wrench with a VERY long arm and a big burly bike mechanic to lean on it

I work on the principle that if someones gone to the trouble of designing something so that it works both ways, to the extent of providing an otherwise unnecessary lever to switch direction, then it is probably fine to do it. Particularly if it is a 20-200Nm £15 item from Lidl (albeit a rather nicely made £15 item) that I only ever use on BBs and cassettes (the latter being somewhat meaningless in terms of torque wrench precision anyway).

The world won't end because of it.

Yes, the reverse threaded verison is only the Ti spindled cranks, easily distinguished by the red circular decal/branding circle around the bolt. Steel spindled is white.

UT cranks are tightened between 46 and 52nm, so they are tight. My SR Ti cranks are R/H threads and I use my Torque wrench to assemble/dismantle them with a torx extended allen key like these:
