Ultra torque Centaur 11 speed Problem

I had a campy record 11 speed ultra torque crankset that started to make clicking sound. In an attempt to correct this I installed a brand new Centaur ultra 11 speed compact crank as I also wanted lower gearing since the other crank had 39 tooth small chainring. However the new crank has side to side play in it. As far as I can tell the drive side clip is in place and I have the wavy washer in correctly. I have the drive side bolt torqued to 42 nm. Any thoughts on why there is this play in it from the campy experts ? I did not change out the bottom bracket cups since they are not that old. Thanks

I vaguely recall that the Record cups were made for Record only and that the other cranks used a different cup. Or maybe it was Super Record? I know there is a spacer kit out there that is meant to be used to remove the play that develops from the wavy washer.

If the clip is in place properly, there should be no significant side play possible. If the crank bolt is removed and the left crank removed, the right side crank arm should have minimal play, with the clip restricting it.

The only difference between cups is the super record have no seals.

I have installed a couple of dozen Ultratorque cranks and the only time I ever had a problem was when the clip wasn't properly seated in the small holes in the cup

I don't completely understand what you mean by seals. The crank I have had the bearings already installed.. I noticed that the bearing cups say 36x24 super record only and the original crank was record and not super record. I am now putting on a Centaur crank with these same cups.. Could this be a problem that the cups are for super record and not compatible with my crank? Thanks

I pulled the crank off and will try installation again. I am confident I had the clip in correctly but it cannot hurt to try again. Thanks

Super record cranks have ceramic bearings and no rubber seals on the cups to minimize friction. Otherwise the cups are the same. The rubber seals on Campy cups can be removed and replaced if necessary. The Campagnolo website has links to spare parts lists that show the details. If you're using SR cups with no seals, the bearings won't last as long with no dirt protection.
