problem found upon cleaning - loose drive side BB cup

stardude

hiya

upon cleaning my road bike today i noticed that there was some play on the BB. it is a giant TCR team 2006 and its a 105 triple crankset and it is an internal BB

upon closer inspection, the drive side BB cup is loose and can move about 2mm in each direction.

am i freaking out over something that just needs re-torquing?
or will it need to come out, cleaned re-greased and re-installed?
is there any chance it might have damaged the threads in the frame???

would i be best to buy a bike torque wrench and a bb tool and do it myself? or get the LBS to do it?

cheers

Without a tight seal water (particular salted road spray) might have leaked into the bearings. I'd say take it out and inspect it, give it a clean and regrease.

As I clean and regrease all 3 of my bikes (all external BB) it's make sense for me to buy the correct tools. If you have 1 bike and do fairly low miles, take it to a LBS.

i'm getting so stressed about it

this is the BB that is currently fitted its still on its first since 2006

well i have this, my MTB and my GF's bike, so it might be worth me getting them then.

i dont think that i can regrease this bb? it says its a sealed cartridge?

I had a similar problem earlier this year with an old Shimano sealed BB (sqare taper - not Octalink - but very similar to the picture posted). The drive side cup was coming out from the frame and it turned out that the threads had gone in the screw-in cup, mine were made of aluminium which had worn away. (I had removed and refitted the BB a few weeks earlier and I think this had caused the problem). I had to replace the whole BB unit.

get it tightened up before continuing to use it or you risk ruining your frame.

i am going to take it to the bike shop tomorrow to get them to have a look at it, as i think there might be some frame damage already, but then again i dont really have a clue about this.

stardude

i'm worried

this is a video i took of it:

does not look good.

That's the same as my problem mentioned in an earlier post above. The left hand crank stopped the whole lot from coming out of the frame. Luckily, the threads in the frame were OK, I only had to fit a new bottom bracket to fix the problem.

Yes, mine did the same as your video - mine actually moved further because the gap between the left hand crank and the frame is larger. Mine packed up on a ride but I was able to struggle home.

Good luck.

cheers you have made me smile breifly with hope lol

if it does go tits up, i found a company called BETD and for £60 they will ream it out, then install a stainless helicoil, which makes it stronger than new and allows you to use a standard BB.

if youre still on original BB and with the price of the 105 octalink, just buy a new one and the tool to fit it (another £10-£15) and do it yourself . you can look on the parktools website or sheldon brown for details. it really is dead easy and you have to say if its lasted 5 years youve had value for money

i would hapily do the change myself, but i fear there is thread damage in there so i want to get the bikeshop to check it over first.

yeah its lasted 5 years with no problems, but not good value if its ruined the threads lol

I have to say that looks worse then I thought. I didn't realise that there was lateral movement as well, I thought it was just 2mm rotational.

Take it to the LBS. BB are cheap, it's just any damage to the threads and frame that might be more expensive.

stardude

its in the bike shop now just have to wait and see what they find.

he said that the drive side bb cup is steel so, it will be the frame threads that will be damaged.

he also thinks it was installed badly during manufacture

i have just realised that i bought the bike practically new from the bike shop, it was a demo bike for a month or two, so could i claim on my frame warranty?

i am going to ring the bike shop and see what they say.

boblo

Call the LBS about a bike you bought in 2006. Are you serious?

yes i am serious about calling them about the expensive bike i bought from them in 2007. have you heard of a 'warranty'?

if you have nothing constructive to post then dont bother.

boblo

No you go in and embarass yourself. That's fine.

The warranty will apply to parts and frame.

Parts usually 12 months against manufacturing defect.

Frame warranted against manufacturing defect period dependant on manufacturer, could be up to the lifetime of the original purchaser.

The frame bottom bracket threads will not be warranted against hearsay from another LBS or user abuse/lack of maintenance 4 years down the line.

Anything could have happened in the intervening 4 years and you clearly know little about maintenance (not being rude, your own confession). In that case even if the BB was 'installed badly' 4 years ago, it is not unreasonable to expect some routine maintenance and if it's just gone, this suggests there has not been any. This of course, could be seen as a contributing factor to the damage.

You did ask for advice and mine is, you're taking the pi$$.

stardude

just spoken to the bike shop

only the first 4 or 5 threads are damaged on the drive side. so thats better than i was expecting

what they reccomend is getting a new chainset - ideally the tiagra, the current 9 speed chainset

they reccomended me this option as it uses the external BB which goes further in and uses more threads.

i think i am going to go for this option as i get a new chainset, new better BB

and i dont have to strip my frame down and post it away etc etc

so it will be £150 for the new tiagra tripple chainset, new hollowtech BB, facing the shell and fitting and setting up.

if they chase the threads before fitting the BB cups you should be OK. Sounds like a sensible solution.
