…Having been taken in by the oft toted ‘it’s sooo easy’ type-exuberance about changing Hope bearings on STW, I went haplessly ahead with the hammer and things.
All I’d say is, be careful. Getting them out is straight forward enough, I suppose, but getting them back in is where problems can arise. Use a correctly sized drift to get them back in again, not just something vaguely the right size. And, ideally, press the new bearings back in with a vice-type-contraption. A Black and Decker Workmate, or similar seems to do the trick really well. Study the ‘exploded’ diagrams on Hope’s website carefully too, beforehand so you don’t put something back the wrong way, or miss something out entirely
TJ’s advice about heating and cooling different bits is, quite frankly mental. Unless you have a work area with access to a very efficient freezer AND a hot saucepan nearby, and are very quick with your hands, handling hot-hot-hot things… you’ll simply find that the components, especially the aluminium freehub will find their way back to room temperature very quickly indeed… too fast to make much of a difference.
Alternatively, take it to your LBS and get all 5 bearings in the rear wheel changed if you don’t feel at all confident. (There’s no shame in this!). Afterall: a replacing a mangled freehub will be 55 quid and the new bearings themselves (if you mangle them too) will be 15-25 quid, depending..
Good luck! 🙂
