replacing BB

first time doing this job. All seems pretty straight forward, just want to know if I should grease the crank before slotting it back in? Also, there is green factory grease on the 105 BB I've bought - should I leave this on and also add some copper grease to the threads on the bike and the BB?

thanks

    As in grease the crank spindle? I personally do, just a light smearing - avoiding the end section/clamping area. I don't remove the factory grease from the BB cartridges but a quick inspection should indicate if adding any more is required. I will also clean and grease the threads on the BB shell and also apply a little grease to the BB threads. I use a general purpose grease for the whole thing (Finesse).

    yeah the spindle. Got some general purpose grease I can use on that. is it bad the mix the factory grease with copper grease? Just i was under the impression you should stick to copper grease for threads?

    Grease for bits that move and anti-seize for bits that don't but you might want to remove at a later date.

    Hit my first hurdle - the old bb was an SM fc5600. This new is a 105 sm bb5700. Was told they are compatible but the "L" and "R" symbols are on the opposite adaptors with this new bb. Does this matter which way the inner cover goes in?

    There is also mention of a spacer and ring for triple chai wheels. I've got a triple setup but no spacer on my old bb...

    Pls help!!

    Straight swap - inner sleeve isn't handed either, should fit either way around

    All sorted. Bit of a nightmare as the crank would not slot all the way back through. Got stuck with a cm left and had to hammer it through with a towel to soften the blow. Turns out there was a spacer on my crank after all.

    Anyway job done. Rotating smoothly with no play so happy days.
