How the fuck...

Are you just meant to wrench the spacer sideways as hard as possible and then hammer like a madman around the breaing edge with a screw driver/long allen key?

Is their any actual skill in it?

And what exactly does a drift look like? As i could probably fashing something just as good.

I also have a spare axle, is that any good for doing it?

Just did the rear.

Piece of piss (ish).

Simply because the spacer was moving more allowing me to welly the cunt.

The front barely gives me a mm. Is there anyway to force the spacer aside?

Pretty much. Make sure you remove any dust seals and cipclips first.

It is a LOT easier with a proper drift, you sometimes only have a tiny little lip to hammer on. You'll fuck the threads on your axle if you try to use that.

You need to be a lot more careful putting the new ones in.

i'm going to undertake this task on friday, the sprocket carrying bearing is scuppered, so going to attempt to sort it myself.......

do i need to get the wheel rebalanced after changing only the sprocket carrying bearing?

cheers

They don't usually balance them with the sprocket carrier in place, so no.

Although I can't work out why, it seems to me like you should balance the whole wheel and hub assembly. Maybe someone else knows?

Bum, wishing i hadnt read this now... making me think ive hashed it up (and i were so proud earlier).

So how critical is it to balance it when new bearings are put in... ?

How critical is this put them in and take them out business. As when mine were in they were staying in.

And i tapped them in with a smaller socket working a criss-cross pattern round the outer rim.

IE covering inside and outside race at 6 oclock, then 10, then 2. Little taps. Fuck loads of grease.

Ive got to the point now were ive fucked up the old bearings too much to stop. So gonna invest most of my time trying to get the spacer moved abit to increase the lip.

Out of curiousity, how bad are little dents in the spacer? Or having a fuck load of rust on the OUTSIDE (ie in the hub side not axle side) of the spacer. Metal was thick and meaty so just filed it abit and covered in oil.

Thanks for the reply mate Thumbs Up

I may go and treat myself to a drift, to go with my absolutely huge half inch drive torque wrench i got for 16 quid Neutral

Think i may avoid doing engine bolts with that one lol.

So is a drift meant to be the same diameter as the hole in the inner race of the bearing, or slightly smaller? or very much smaller.

Im off to go sit outside, in the rain, and repeatedly club it with something until it moves enough to get a proper purpose.

The annoying thing is (as i found with the rear), once youve got the 'sweet spot' it comes out in about 6 good hits.

A 'drift' is whatever you're hitting with your hammer to drive out the bearing. I've always used a flat-headed screw-driver, though you can buy a dedicated tool (called a 'drift' Laughing ).

Which bearing are you having trouble removing, the first or the second in the wheel?


Hmm, well that screws my plan as i was intending to hustle down to the tool shop and buy a drift. Might go anyway and see what they have but so far using the edge of a chisel is about the only thing ive got any luck with.

Its the ruddy spacer in the middle i tells you. And first bearing. Im assuming once you have once side out you get the spacer out and the second is a piece of pish (or it was like that with the rear anyway).

Im quickly running out of jobs i can do until the wheels back on Sad
Just finished stripping, cleaning, greasing and fitting new pads to the two front calipers and cleaning the wheels.

I guess im just lucking for a better solution then 'keep forcing a slight lip by wedging the spacer in a random direction, then spank it with a chisel/screwdriver as hard as possible'.

What about something like this or this - (scroll down about 5 entries, its the one with pics)

Might go down with my bearings and see if i can get a ground anchor. Worth a punt.

I'm suprised you can't shift the tube enough to give yourself a decent lip to hammer at. Maybe you're being too gentle?


6'4 boxer with more threaded bolts and snapped parts to his record then anyone else.

I doubt it.

Mums just bunged me £20 to get them removed by someone.
I figure i can either go hastle a garage for cash in hand but theyd probs want more then £20 Rolling Eyes
Or buy some tools out of the £20 and do it myself (but i really am getting no where and time is of the essence).
Or bribe someone who can do it to come over in exchange for beers...

Hmmm Thinking

Lip is literally at best 1mm, but i think im not getting enough purchase with the various devices ive been using.

Maybe the nature of these parts means that they are manufactured correctly balanced?
