Wear and tearOver time the cranks have slowly come to the 5-6 year old age where things start wearing out. I knew the bearings were on their way out a while ago when I relubed the sealed bearings. They needed to be replaced, however this would require special tools to remove the bearings. The Campagnolo Ultra-torque cranks are unique in that the bearing itself is attached to the crank not the bottom bracket cups like Shimano or Sram.
One of the consequences of this design is that you are required to use a bearing puller to remove the bearings from the spindle, you can get a dedicated one for about £50, however after doing a bit of research I found you could use a £9.50 one perfectly fine. It is the Yato YT-2515 and only needs mild modification to the claws, they need to be filed slightly sharper to be able to fit in the gap between the crank and the bearings.
Secondly you need a tool to press the bearings in place, the spindle diameter is 24mm so I used a 28.6mm pipe with an inside diameter of 25.4mm. This allows you to hammer the bearing into place
The picture above shows you what's needed:
- Bearing puller (Yato YT-2515 shown)
- Short bit of pipe with an internal diameter of 25mm or so
- New set of bearings (Campagnolo Part No FC-RE012)
- Set of Campagnolo Ultra-Torque cranks
1. Removing the bearingsIf you are using the Yato puller, give the claws a slight sharpening using a file.
All clear! Now onto the next step...
2. Installing the bearings
Now you have the bare cranks, give the bearing surface a little bit of grease, then slip over the black dust seal making sure it is seated properly and clear of the bearing seat.
Place the new bearing onto the axle and place the 25mm ID pipe over the bearing, using a mallet or similar tap the bearing into place until it is seated properly.
All done! Now the bearings are done the cranks are ready for action. Thanks for reading.
