Hi all,

Just bought myself some bling proper oz wheels

Getting them powder coated to my preferred colour, but, does anyone know how too take out the bearing (without damaging them!) prior to me getting them coated

Cheers in anticipation,

Greg.

Just buy new ones you tight git!

Seriously though, its difficult to get them out without absolute confidence you're not doing any damage. For the cost of new ones (go to simplybearings.co.uk for new bearings and seals) it'd be silly not to have that piece of mind. Give me a shout if you want a hand getting em out though.

What are they made of?

If it's aluminium you could heat them up with a hot air gun and drift the old bearings out. Same procedure but in reverse for the new ones.

If they are made of magnesium/titanium/someotherpanium then I son't know but it may work.

why not tape the bearing up?

Hi all,

Cheers Bigun, might take u up on that. They are made of steel and stainless I think! So no heaty uppy, otherwise, the housing will melt

You can't tape them up, they will be going into a heated oven to be powder-coated, not a done thing

Might buy a bearing puller, they aren't cheap thou...

I'd not be happy to reuse a set of bearings that had been pulled. Either drifting or pulling them has to transmit a huge pressure to the outer bearing surface through the bearings and inner bearing surface. I'd be concerned that they could be damaged, but not obvious to the eye. Considering the stressful job they do and the speeds involved, I'd go for new. Must be a fraction of the cost you've just laid out on the wheels.

Another vote for replacement. Once they've been drifted or pulled out, they're fit only for scrap IMHO. If you take the bearings into a local trade bearing stockist and ask them to match them up, you'll get them for cheap anyway. What ever you do, don't buy them off an Aprilia dealer!

And you can't leave them in, as the heat from the oven will totally knacker the grease in the races and the plastic seals they fit to keep the grease in.

Hi all,

Point taken, I will put new one's in

Just want too be careful when I take them out

Will source a decent puller me thinks....

you'll have to 'drift' them out using a small enough diameter bar to fit through the spacer in the wheel centre.

D-Rider · #10 Post by **D-Rider** » Tue Jun 30, 2009 10:39 pm

Drifting the first one out is nigh on impossible due to the design of the internal spacer tube in the hub - you just can't get anything through it and on to the bearing to drift it out.
I guess a puller will do the job - I didn't have one so I cut the bearing up with a dremel.
Once the first one is out, drifting the second one is easy.

Try your nearest Aprilia dealers, I bought the new bearings at Biker near Romsey and they removed the old ones free of charge.

My local aprilia dealer doing something for free

Never in a month of sundays will M+S in ncle do sweet frig all for free!

simplybearing.co.uk is place for bearings people

Got the bearings out without any damage

The wheels, mille swingarm, and rear wheel hub are now getting a shiney new powder coating put on

The wallet is getting emptier by the day not month!!
