Garage Night Episode 10: Replacing rear wheel bearings WATCH NOW!

It's the first instalment for 2009 of our web video show about working
on bikes.

Something's dodgy with Pete's rear wheel bearings and they need
replacing. "It wasn't me," Pete insists ...

All the best everyone,

Hey Lizard,

Good question. I know what you're saying. But I think you would find
that you would need such a big needle to let grease through, it would
damage the seal more than if you just do what trent did, ie pop the
seal out using the blunt side of a pocket knife blade.

Others may know of alternative methods; personally I had never even
thought of opening up a sealed bearing and packing it before trent
showed me how.

Thanks for the feedback,

Yup, in the case of wheel bearings. But when fitting, for example, a
lower steering head bearing, you whack on the inner ring.

In short, you whack on whichever ring of the bearing will be in press-
fit with the component. Some bearings, like wheel bearings, are press-
fit via the outer ring to the hub. A lower steering head bearing is
press-fit via its inner ring to the steering post.

After having assisted in a bearing transplant operation as scrub nurse,
voice of reason [1] and also second assistant swearer during a transplant
on the front wheel of my mate's Fireblade [2] I must say I was
disappointed overall in the video.

I feel it was not a particularly true to life example of a bearing
transplant operation.

They just came out!

Damn! I was dissapointed.

No swearing, no bleeding, no discussion over tea as to whether heating
the wheel would expand it enough to get the !**ts out or whether it would
weaken the metalic crystaline structure of the alloy wheel. No long line
of increasingly oversized hammers, mallets, crowbars, sledge hammers etc.
Not even a minor thumb, hammer interaction. No quietly whispered
conversations, out of hearing range of the bearings of course [3], along
the lines of "**** it! Lets drill the bastards out!" as the futility of
the operation embarked upon, starts to dawn. No greasy fingerprints on
the computer keyboard whilst googling for clue, only to find no solace,
no hope, no help and oooh! Look at the size of those.

Nope!

None of that!

They just popped out quicker than tits at a lapdance club when presented
with cash.

I was so hoping for a more Reg Prescott DIY approach to the whole thing.
Entertainment. We want ENTERTAINMENT. Failing that blood and a giggle at
someone else's misfortune would be good.

If not that, then how to deal with the stroppy ones would be a good
subject to cover. There was no mention of the fact that bearings may want
to stay in the wheel despite all enticements to come out.

[1] You don't want to do it like that you might hit your thu....... Oh!
[2] I have no idea how the front bearings got knackered in such a low
mileage.
[3] Everybody knows machines have feelings too.

Anyway nice effort. Thanks.

Heh. When I reconditioned the Notrun's gearbox I bought a Mick Hemmings
DVD that goes through the whole process.

At one point he removed a locking collar with the words "Now, these can
be a bit toight, loike. But.. Oh! This one's joost coom aht!". And it
did too. Barely hand tight.

Mine? Fucking welded.

I ended up doing the whole heat / cool / drift / twat it with a BFH
thing until it finally succumbed to a really sharp cold chisel.

I lost a little faith in St Mick after that...
