To grease, or not to grease?(11 posts)

To grease, or not to grease?joe friday
Dec 9, 2003 9:05 AM
i've read somewhere that before installing a Record
b/b the frame should be clean, clean, clean..

It's kind of counterintuitive to my mtn. bike experience,
which was to grease everything with a thread, but it clearly
says, "free of all oil, grease, blah-blah-blah"

So i ask, should i grease?

Yes grease the threads and then really yank it down tight.
Grease or anti-sieze.jw25

Me, I'd go by Campy's instructions. Unless they say clean, grease those threads or apply some anti-sieze. Given the size of the threads, the torque applied, and the proximity to water and grime, I want something between the threads, so I have a chance of getting the BB out when it finally wears out.

I think you're getting a few "rules" mixed up. You grease the heck out of the BB shell. Its the spindles that are supposed to be clean.

Now we're going to have the grease vs. not grease the spindle argument... (Personally, I wouldn't bother trying to "convert" anyone 'cause you're not going to change anyone's mind, but if y'all want to re-hash something again, feel free.)

I believe campy puts a loctite type of antiseize material on the threads. For this to work correctly the mating threads in the shell need to be clean and free of all oils and grease. Make certain it is torqued down properly at time of installation and then don't mess with it.

Now, if it is a used BB or you removed one and put it back in I would clean the "stuff" off the threads of the BB and the shell and then use grease or better yet anti seize.

If the BB is new and the manufacturer put a strip of loctite around the BB threads, then the BB shell needs to be free of grease for the loctite to bite properly. I just installed a Truvativ Gigapipe BB on my MTB and it had the loctite on the threads...therefore no grease.

The thread locker on the Campy BB is only applied about 10mm wide around the center section of the threads. In my opinion it's only good enough to function as a filler or whatever. If you like using thread locker on your BB you have to cover all threads and hope that some day you'll be able to remove it again:)

Campy is only specific about not using grease on the spindle and Shimano even recommends using grease on the BB cup threads, even though it contains a thread locker.
Teflon tape?fallzboater

Anyone wrap the cup threads with Teflon plumbers tape? I've tried it a couple of times (old DA cup-and-cone BB), thinking that it would both help keep the adjustable cup from loosening, and ensure that I'd be able to get it apart later. Seems to work OK, although it's a bit of a pain to get it out of the threads after servicing.

Teflon tape does fill in the gaps, but when you torque the BB, this forces at least one face of the threads into VERY close contact with the frame, so there's really no gaps to fill. The weakness to tape, IMO, is that it doesn't provide a protective film like grease does. The grease will prevent corrosion and seizing better than tape. However, many people use tape exclusively and are quite happy with it, so it obviously works.
it's in and i'm very happy!joe friday

thanks very much to everyone for helping me with this
project. it's taken two months to gather all the parts
but now it's done, whew!
