Hub service drama

[Milzy]

I had new bearings fitted to a wheel. When I got it home it was very out of true.
Why didn’t they put it in the stand after using pulling tools?

Probably a question for them rather than us....

What sort of bearings? Whether they're sealed bearings or loose ball bearings I can't think of an instance where I could screw up the trueness of a wheel. If you take it back they'll swear it wasn't them.

No obvious reason why replacing ball or cartridge bearings would put a wheel out of true surely ?

Unless they hammered them in on the floor. I’d question the worth of those bearings now.

I used to work with this guy, Matt The Mallet. Could never be bothered to find the press, he used to just bash them in including pressed in bottom bracket bearings in carbon frames.

we fired his butt.

but he’s still out there…

Is it out of true or off-centre. If the latter, I think I understand what went wrong.

Agreed but the wheel would still be 'true', so to speak, but off centre. @Milzy have you got a dishing tool? Really, there's no way they could screw up the trueness by firking about with the axle when they changed the bearings. None that I know of anyway and I've screwed up a few wheels in my time

I had let bearings replaced, went back to pick up the wheel, decided to directly mount to be sure OK, walked the shop out with the bike at hand, and while doing so the wheel all of sudden showed alot play. Returned and the culprit turned out to be a ball too much, which pressed the cup and cone away from eachother, resulting in that play. The wheel not out of true, but when turning it looks like it is.

I asked for it to be trued after service but they didn’t listen. It’s just it was more out of true than when it went in.

I suspect this happens more than you think. Took a bike in for a full service once and made it clear the BB bearings needed replacing. Day later they call me up saying the chain and casette needed replacing (they didn't). Told them not to, just do the service and bb. Go to collect the bike, turn the cranks and the bearings are still gritty. Ask if they are replaced "no, as you didn't want the chain and cassette doing we thought it best to leave the whole drivetrain". Needless to say I didn't return.

Mallet in hand, waiting for your shiny carbon. The more expensive the better!

Unless you don't have a clue what you are doing 😉
