Bottom bracket query

[eric_james]

If you'll only ever do it once then this is the cheapest tool option. Socket version are available but a tad more expensive.

Yes, undo pinch bolts on non drive side and slide the whole axle out.

@novocaine

will this definitely fit?
I'll order it now
thanks bud

 

[novocaine]

Yes and if it doesn't (it will) send it back (it will fit).

cheers

Have you got any way of measuring the chain, because that inner ring looks very worn to me.

 

[coomber]

And as you have no replies, I'd slap grease on the whole of that axle that goes through the bb when refitting. Just a small coating

 

[eric_james]

Brand new shimano chain, seems to ride fine in the inner ring

I've got that tool coming so will try to overhaul the BB and see if the creak stops

Thanks coomber

 

[eric_james]

Thanks @novocaine

Tool is here, will sort the BB out tomorrow

I'm getting a very slight creak
have had this before and it was the pedals, changed pedals and still there

Also the bike hasn't turned a wheel in ages...had a bike that had been parked up for a while and the creak went away after use

But, can I remove the BB and clean and grease it up?
will that work

Creaking can be from it not being preloaded correctly, or worn bearings. I'd regrease, and if persistent replace the bearings and see.

I didn't get a notification

Yes, will see Imlach, I've not done any modern cranks / bottom brackets before but have watched some videos

Saw that some use ptfe tape, only a small amount

I don't have very extensive experience with them either. I've got 3 bikes with external BB and they all have had issues with creaking which were either fixed by cleaning or adjusting crank preload. Hope you'll get it fixed tomorrow I hate creaking sounds or squeaking sounds
