Ultra Torque Bearings
Had my LBS replace my Record UT bearings last year as the originals had gone rough after 5 years and many thousands of miles. However the new ones are already noisy and I decided to have a go at the job myself. I've got them out and the shop replaced the originals with SKS 7149783 which are the 2 rubber seals type. I want to replace them with a good quality bearing that aren't going to be silly money. Campagnolo items can be had from circa £20 but if anyone can recommend a size and type that I can get from my local Bearing Factors I'd be grateful. Not fussed if it's ceramic, hybrid or steel as long as it's of good quality.
Also looking for a ghetto solution to drifting them back on the semi axles without having to purchase an expensive propriety tool. Looks like a piece of steel tube will do using the old bearings to protect the new ones as they are tapped in. Anyone done this?.
Thanks.

However Enduro do a version and I replaced my original UT bearings with these and am very happy.

As for refitting try and seat the bearings in the cups on the frame as evenly as possible and install the crank without wavy washer and tighten up.Then remove the cranks and put on the circlip on the driveside crank arm and the wavy washer on NDS and install.

Let us know how it goes, drifting the new ones into place and I might start doing this job myself.

Once I couldn't find the tube to bang them back down, and, yes, I used a piece of tube.
Good to see you're all sorted.

In any case you dont seat the bearings on the axles by drawing the two halves of the crank arms together with the bolt. That can cause damage.
A steel tube can and does seat the bearings well if it's the right diameter.
A hammer however is not the best tools for setting them. The cyclus tools I have seat the bearing with a press I.eno shock load.
It's difficult to tell if your chosen method has caused any damage or not but one thing I do know not many shops ha e the tight tools. The shop that did the job last year may have done the same as you. Bearing damage and early failure is certainly possible.
