Noisy new freewheel

[rh100]

I know the real solution to this is buy a better freewheel, but.....

I recently replaced a 7 speed freewheel on a trek 7.1 I'm putting up for sale, I now have all the gears shifting beautifully but there is a dry, almost but not quite grinding noise coming from the freewheel when it is freewheeling but not when turning the cranks.

Ive re oiled it, but not much different, and I don't think it's the hub.

I've checked the spoke guard is not rubbing against the inside of the cogs.

Is this normal for a new freewheel? Is it likely to wear off or shall I pull it off and get a better one? Not really happy selling the bike with a noise like that on it.

Thanks for any advice

Was it making a grinding noise before you put it on ?
Freewheels are supposed to have grease in, when you say you "oiled it" you might have been washing the grease out.

Thanks, No there was no grinding before. I didn't go ott with the oil, not enough to wash any grease out.

Is it possible the lockring is loose? Is there a lot of free play in the freewheel bearing?

Maybe some grit on the hub?

No lockring as it's a freewheel, rather than a cassette. Doesnt seem to be any play either

There is a lockring with two small indents for a pin spanner which holds the bearing and freewheel mechanism together. It has a left hand thread.

I did wonder, but I can't get the bugger off now to give it another clean.

Think I'll get another better quality one

You still will need to get the old one off

Are you thinking of the old sun tour type?

This one uses a tool similar to a normal cassette tool but unscrews the whole body from the hub, unless I'm missing something!

I know lolEither I finally get that vice I was given bolted to a bench, or I buy a long bar to lever the spanner, or admit defeat and head for the friendly lbs

I'm talking about the bearing race/lockring which holds the body of the freewheel together. If you unscrew it completely, a billion tiny bearings and some pawls and springs will drop out and you will have great fun trying to re-assemble. I have seen freewheels (mostly cheapo BMX SS ones admittedly) which had the bearings too loose and were noisey. Tightening it made a big difference.

Ah right ok, just looked it up and I see what you mean.I'll have a look tonight and see if my pin spanner will fit, cheers
