New rim bearing question

[Yroundrdn]

I finally purchased a new front rim. The prior owner somehow bent the one on the bike so I broke down and bought a new one. I also bought bearings and seals.

Do the front bearings need to be pressed in with a press or will the 2x4 and BFH work?

Go the local hardware and get some booker rod (threaded rod), nuts and washers.

You can pull the bearings in using the rod and a couple of right size sockets, easy as.

Or stick them in a deep freeze overnight.

I don't know what the tolerances are on the bearing races, but I would not use a BFH. Definitely cool the bearings. they might just go in with gentle tapping. Anything more than that might gall the race. If they must be pressed in then take the wheel somewhere that can do it. Don't want to create another problem after fixing one.

+1 on the threaded rod approach. Allows for a huge amount of force and much more control than a sledgehammer. It's a real pain in the *** getting bearings stuck in at a slight angle. Don't ask how I know.

And the BFM is hard on the bearings too. While I was able to get a set in a little ways myself using the freeze trick.....it warmed up by my second or third tap and it turned into getting a a BiggerFM and pounding the bejeezus out of it and having to replace them anyway with my first tire change. Spend the $15 bucks or so and have 'em pressed IMO.

If you use the threaded rod method, make certain that pressure is applied to the outer bearing cups..not the inner

excellent, thanks guys

I'm a electrical fitter mechanic and have done heaps of bearings that way.

As mentioned above, you just make sure you have the right sockets to fit the outer bearing.

It's also a good method to remove bearings from housings.
