I've got some moby mags that have shot bearings. How do I get these out? I haven't had any luck rigging a puller, so I'm guessing they need pressed out. Who has replaced these before?

Re: Sealed bearing removal
I think they get heated and they just fall out at like 200 degrees f.
Re: Sealed bearing removal
place a drift or a 3/8 or 1/4 in socket ext in from the other side .
place wheel on table on 2 blocks of wood so wheel is supported and bearing is not
hammer out bearing from opposite side
the real way:
buy a blind bearing puller. use a slide hammer to remove bearing

I wouldnt use a torch to heat up those mag rims.
Magnesium catches on fire when held to a torch.
Re: Sealed bearing removal
mopeds do not by any means have magnesium wheels
Re: Sealed bearing removal
my moped has uranium rims.
Re: Sealed bearing removal
why are they called mag wheels then?
Re: Sealed bearing removal
it's a style... like spoked.
Re: Sealed bearing removal
It may be a style but a lot of original moped rims,motorcycle rims, and even car rims were made from magnesium or magnesium aluminum alloys so just be carefull. Shave a little metal off with a knife from an unoticable spot and see if it ignites. If not go for it. I just dont want anyone getting hurt or destroying a 100 dollar rim.
Re: Sealed bearing removal
mag rims are just a name....like mag bmx wheels from the 80's.
They are not made of magnesium.
Re: Sealed bearing removal
research

Re: Sealed bearing removal
sorry man. no mopeds have magnesium rims... some aftermarket car rims are, and some crotch rocket. but not mopeds
Re: Sealed bearing removal
example 2
Once again just want people to be carefull and not take an oxy acetaline torch to something that could catch on fire and melt a hole a foot into the ground
Re: Sealed bearing removal

Re: Sealed bearing removal
nope im not
Re: Sealed bearing removal
what moped did those come on then? where are the brake accessories?
Re: Sealed bearing removal
Thats from a bmx bike from the 80s. mopeds,motorcycles,cars,bikes all kinds of stuff use to have magnesium rims. They usually dont use them anymore because they are highly flamable. It was a lot cheaper back then to make magnesium rims then alluminum ones. Thats why when working on old cast metal rims you should always use caution and make sure they are not magnesium before you apply heat to them
Re: Sealed bearing removal
mopeds did not............
Re: Sealed bearing removal
you are incorrect my friend
Re: Sealed bearing removal
i'm done. if anyone comes up with a magnesium rim on a moped i will send you $10.
Re: Sealed bearing removal
i have personally worked on rims from a puck newport that said MAGNESIUM on them. Also i just happend to have my rear rim of my fantic motors pepi sport in my house due to a flat tire i was changing. So i decided to shave a little metal off and it caught fire when i held my bic up to it. So i guess some mopeds do have magnesium rims. My puch maxi with magnum rims are not made from magnesium as i allready tested those a while back to see if i could weld a crack in it.
Like i allready said just use cation. some mopeds have magnesium rims. some dont
Re: Sealed bearing removal
anyone else seen a newport rim that said magnesium on it? my offer still stands
Re: Sealed bearing removal
get a long punch and a mallet and pound them out. Thats what I did on mine. Worked like a chamP!
Re: Sealed bearing removal
The 1/4 inch socket extension did the trick. Thanks to Matt for the only useful post in this thread (albeit the least entertaining)
Re: Sealed bearing removal
