    Punch it out a bit from the inside maybe.

    Tbh I always just used a piece of 2×4 and hammerd that thing in. Even if it was slightly crooked at the beginning.

  2. I second the 2×4 and hammer approach. It will be fine. The other option would be to take it to the local bike shop and get them to use their bearing press

  3. To keep it square use a block of wood each side of the bottom bracket and use a G clamp or F clamp to apply force.

    You can probably knock it back out with a screwdriver through from the other side and start again.

    Another trick if you can get it out is put the bearing in the freezer overnight ( in a plastic bag) which shrinks it a bit and just before taking the bearing out the freezer and installing it warm up the frame with a heat gun which will expand it. This should make it just drop in easy when everthing cools / warms up it will be tight in there.

  4. Fisrt off, grease it before it goes in. Then, if he’s not using a bearing press, he can hammer it in by tapping all the way around the outside of the bearing. This will help prevent it from going in crooked. Hopefully.

    Easy. Put some force on the part that is sticking out more, and gently tap it out from the inside, on the side that is stuck in more

    And use some grease the next time you press it in

  6. Heaps he can do. Knock it out from the other side if he wants to remove it. Use a bit of wood and mallet to tap into place.
    Make a homemade press out of thick bolt, nut and washers larger than the bearings. Tighten up and the bearing is in the slot. And chill. Getting upset just makes it so much slower to fix. When he’s calmer tell him the rear tire is backwards.

    So annoying when a BB bearing starts going in wonky enough that you have to start over. At the angle it’s at there he might risk damaging the bearing, or worse the BB shell, so I’d knock it back out using the handle of a socket wrench or something like that and just start again.

  8. Use a flat head screw driver from the opposite side with a hammer to tap out, push out the bearing. Then re-align the bearing again against the bottom bracket tube and place a 2 x 4 on top and hammer it in, or use a rubber mallet to hammer in the bearing.

  9. Are you looking to get the bearing in place or out of the frame?
    Getting it out can be done by sticking something through the bearing hole on the other side, preferably a piece of material softer than steel and (gently) hammer it out. (I usually go up, down, left, right)

    If you want to get the bearing IN the bb, it’s quite easy to make your own press, if you want to avoid using a hammer.
    Just use a simple piece of threaded rod, two nuts and something (or actually two somethings) big enough to cover the bearing, like some plastic rod or a piece of wood with a hole drilled for the threaded rod to fit through.
    Nut the thread on one side, then use your plastic or whatever presser, and stick it through both bearings.
    Then apply the other bearing presser and finally screw on the other nut and keep doing so until the crooked bearing has positioned itself.🙂
    Perhaps a couple washers will be useful to protect your pressers, but not absolutely necessary 😉

    If you still havent gotten it take a brake. Go on amazon and look for a cheap bearing pusher

  11. Is he trying to remove that bearing or install it?

    If he’s trying to remove it, I just did a similar job removing my dirtbike’s wheel bearings and [this kit ](https://www.amazon.com/dp/B0DL3J5M1H?ref=ppx_yo2ov_dt_b_fed_asin_title)and heat gun made the job super easy.

    If he’s trying to install it, Autozone has a [bearing installer](https://www.autozone.com/p/oemtools-bearing-race-and-seal-driver-set-57119/391360) as part of their loan a tool program. Might be worth a try.

    For next time, it can be helpful to put the bearings in the freezer overnight and heat up the bottom bracket shell when installing. They basically just drop right in then.

    It’ll be critical to have it go in more evenly so it doesn’t jack up the bottom bracket shell

    Cool of you to help your fiance out with their hobbies!

  12. Rubber mallet. Or if your that worried get a bearing cup press, on frames that are tight squeezes like my DRK Sunday frame I used the bearing press, smooth operation just make sure you greased the cups and bearings.

  13. Yeah I’ve slapped bearing in with a pipe wrench before you’ll be fine just put a piece of 2×4 on the bearing and smack the hell out of it. The bike and all its parts are built LITERALLY TO GET THE SHIT BEAT OUT OF THEM.

    Just take it to a bike shop and have them install the bottom bracket properly for like 20-30 bucks. They’ve got tools that make it way easier than doing it at home 

  15. Personally I would use a 2×4 or a rubber mallet to not damage the bearing. As others said he should grease it.

  16. I always like to put the bearings in the freezer and the metal will contract slightly then hammer them in. but with a bit of wood between the bearing and hammer

    Tap it out from something through the back side. Apply little grease inside and on bearing. Flat 2×4 sideways against bearing and a decent blow direct and center. If its slightly uneven adjust the 2×4 to the high spot and repeat its fine.
