Guys and girls,

A friend of mine has a Look 695 SR (mondrian) and it seems that the crank is stuck! The bearings seem to be a bit rough as well. We have been trying to get it out of its BB, but the crank (that should slide lineair out of the drive side bearing, before you can tilt it out) won't move.
We realy need your help as we are completely astounded by this.
:shock:
Thanks in advance!

Use rubberend hammer on nondriveside crank and if it doesn't help then give some heating to bearings. :thumbup:

I'll give the advice a moderator I know would: Have you tried contacting Look?

Knowing Look, I seriously doudt that they greased the bearing/frame contact surfaces from the factory. Chances are the bearings have began to rust on the outer diameter, effectivily seizing them in the frame. I would try to drop some penetrating oil in the BB and then softly tap the NDS crank arm with a rubber hammer.

Thanks guys! it seems to be that we were on the right route. Hitting a CF crank with a hammer is hard though. Any other people who have seen this issue?

Use a soft-blow Mallot, not a hammer. Not a dead-blow mallot either.
Mallot is also spelled Mallet sometimes. This is in English. In dutch it would be houten hamer.

I won't go into the differences between them and why they are used when they are in furniture making/carpentry - but use a mallot with a relatively soft rubber end to the impact surface.
A dead-blow mallot is typically made of a hard plastic (or sometimes curved metal) with sand inside of it which moves and if you shake it you can hear the sand inside. Don't use this one.
A regular mallot is just hard, not soft. Sometimes of wood. Do not use a regular mallot.
A hammer is... a hammer. Many types of hammers out there, but don't use any of the variety for this purpose. Don't use a hammer for this.

I have done it for our teambikes. Trust me, it is really tight when removing crank first time, but after that it is quite easy to remove.
Use soft rubber hammer or soft-blow mallot as prendrefeu said and don't hesitade and give it some tight hit. Warming a bearings might help a also.

Just built up my 695SR. Having an issue with the ZED2 crankset with Look chainrings, has anyone experienced a "Creaking noise" from climbing steeper hills on the small chainring?

my wrench still cannot figure out why, but I suspect it could be either the chainring bolts, or the BB bearings making that noise. Riding on flats is silent, just the climbs are embarassing.. hah :oops:

Update : found the culprit to be oxidation of a couple of chainring bolt washers. Replaced by Look agent...sounds gone!
