Wheel bearings, how, how how!

Getting wheel bearings out.

I know what your going to say, use a bearing puller.
Guess what im going to say?

I dont have one!!!!
Is there another way of getting them out, talking about a zxr 400.

can drift them out if you're VERY carful using something against the internal spacer on my Thunderace.

not sure how the ZXR is setup, but can't imagine it's that's different

erm this is probably really stupid but my middle spacer can move about so i tried knocking them through with a small bar and a hammer, didnt move one bit.


P.s i didnt use the middle spacer to knock it through i moved it so i hit on the back of the fucked bearings.

Hi

Get a chisel (fairly long and thin, possibly an old and knackered screw driver that you do not care about). Put this in the hole on the inside and push the inner spacer to one side (sometimes they only have clearance to move on on end). Then put the end of the chisel though one side and onto the inside race of the bearing on the other side (hopefully the spacer is far enough to one side to allow this, if not keep trying) and start to knock it out.

You will probably have to move across to the other edge of the bearing to get it to come out straight. They come out normally without too much effort.

When putting the new one in place use a something like a large socket as a drift to ensure you only push on the outer edge of the new bearing. Do not forget the spacer, it is important.

All the best

Remember to take any circlips out first There is usually one on the outside of each bearing holding them in.

Then as kickstart says, drift it out from the middle by getting the wheel up of the ground on two blocks (with a gap in the middle for the bearing to drop out into), pushing the spacer to one side and tapping round the middle race until it drops out.

My preferred tool for drifting things is surprisingly, a drift:

In the absence of one you can substitute a long bolt, you need to keep filing the end of the bolt square because it is soft metal and rounds off easily.

Last time I was doing this I used my hammer and my trusty red handled screwdriver.

Hacking buggers lol

anyway,, a hammer and a drift and plenty of patience,, work your war around the bearing hitting it but make sure it is coming out evenly, if not youll damage where is sits and the new ones will be loose.

found circlips prior to posting and they have been removed the whole time. ive been hitting this bearing with a solid metal bar and its not moving for shit. ive given up now and letting the guy at the bike shop do it.

You can use a suitably sized socket as a drift if you dont mind mashing it...

I'm pretty sure the zxr400's wheel bearings are straightforward enough, so i'd guess yours are too (certainly didn't need a press)

In addition to gentle heat (dont know how sensible it would be there) you can use this stuff called "freezer" comes in a can and lowers the tempreture to -30 ish... its been very handy being used with my trusty mallet in the past

Sounds like somebody might have put them in using bearing fitting compound if they are that tight. In which case, good luck!
