Hi all
Is it possible to remove the NU2205 bearing from the mag housing without damaging it?
If yes then how to go about removing it?

yep, heat the mag housing up till it will boil spit, using gloves pick it up and give it a good thumping on a flat surface( I actually use two bits of 4" sq fence post bolted together ) bearing should drop out.

I heat up mag and use an old engine mount the bigger ones not li and they fit perfect as a drift tool and just tap it out it fits the outer lip so no damage

Take the mag housing off, strip it (clips, seals etc), then stand it on a cooker ring to heat it up. The hotter you get it, the easier it will be. Get it really hot, use oven gloves to move it onto a scrap piece of wood and tap it out using a good sized socket. Obviously get the right sized socket ready first. You don't need to whack it, just tap it out. If it gets stuck, heat it up and start again.
Takes longer to describe than to do.

Remove the circlip,pry out the inner oil seal and heat the mag housing on a cooker/hob until it is about 100 degrees c.Next knock out the smaller oil seal,this will in turn knock out the L-shaped washer and the bearing.

Great, thanks for the Ideas! Cant do it at home since we have a gas cooker! I will heat it with a heat gun and try to hit the outer seal out with a engine mount.
