Fulcrum wheel fix

[Kcyclist]

Looking for advice - road bike wheel
Fulcrum racing 7 lg rear wheel - hub flange has cracked unfortunately and wheel is not safe to ride.
Front wheel in great shape with loads of miles left.
Fulcrum S4 rear wheel for sale on e bay - looks in decent shape but needs new bearings.
Is it possible to take bearings from the 7 and put them in the S4 ? What's required in the way of tools and expertise?

It’s not unusual to get flange problems with some Fulcrum wheels. Yes it is possible to swap bearings from the 7 to the 4. You just need a suitable diameter ( home made out of a piece of plumbing pipe if needs be ) drift, a mallet, and a ( home made if needs be, out of a piece of hard wood ) press.

Assuming they are the 6001 type 'cartridge' bearings, its quite feasible but...its relatively easy to damage the races getting old ones out and ending up with a notchy bearing. Fitting them is easy if care is taken.

You really don't know how much life there is left in the bearings in your 7, do you? And as @gbb says, in getting them out you'll likely damage the races a bit.
If you fancy buying a wheel and fitting bearings, buy new bearings, and fit them (will need press to do properly/with assurance).

Thanks for the replies. I'll have a go at removing the r7 bearings as it will be going in the bin anyway.
Looks as though new bearings are quite cheap also.👍

You won't be able to tell if you've damaged the bearings getting them out (assuming the interference fit is a good one). So you risk putting worn, damaged bearings into the new (to you) wheel.

Having the old bearings is handy, you can place them over the new ones as you drive them in...it protects the new ones from impact damage
