Normally use a screwdriver for bb and hub shell bearings but I’m struggling to get purchase on the bearings in a hope pro 2 evo hub body to knock them out

Cheers

Don’t you just use the axle for the hub shell bearings?

Have you levered the spacer between the 2 bearings over to one side before trying to drift the bearings out?

Worth getting an assortment punch set, they're not expensive and having a few different tools gives you more methods of attack. Having some random bits of metal in the right sort of shapes is handy- I had one bearing that was a total bollocks but that a bit of old threaded bar took out no bother.

But I bsically have 2 that I use the most, one is a fairly thin machinist's punch that got completely mangled at some point and is both bent and a bit mushroomed at the end, which is amazing for getting into little gaps. And teh other is the rear axle from a '00 suzuki sv650, which is perfect for really smacking stuff.

Buy a set of parallel punches and a soft brass or aluminium drift you heaven!

Just realised you can push the inner sleeve to one side. Thanks for the responses I’ll buy that punch set now

Personally I like parallel pin punches which taper to the handle (prevents skin getting pinched and damage to the work piece when the punch slips.

Rather than these

Both types work, I just tend to reach for my tapered ones first 90% of the time.

On my formula freehub, you have to move the spacer/sleeve to one side and drift out the outer bearing. The inner bearing is secured with a circlip - fortunately I realised that first time when they wouldn't press out !
