Removing my BB30 Crankset

Postby RRalphy » Wed Oct 23, 2013 8:10 am

Hi All,

Just wanted some advice on removing my BB30 crankset as I am getting a squeaking sound and I want to clean and re-grease the BB etc. I can remove the drive side easily enough (just use a 10m hex key) but when I get to the non-drive side there is a washer kind of thing around the nut where I would insert the 10m hex key and written on the washer is "do not remove".. is this telling me I should remove that crank arm?? I will take a photo tonight and put it up to make it a bit easier to understand what I mean.

Has anyone else encountered this before? am I ok to remove the arm despite it saying not to on the washer?

Cheers

What cranks do you have?

My FSA cranks have only one hex nut on the non-drive side which you loosen to remove that crank arm, and then tap the shaft through the BB 30 bearings to remove the drive side. The cap on the non-drive side is there to cover/protect the hex nut thread and the end of the shaft from moisture/dirt etc as far as I understand it, and shouldn't come off when you loosen the nut.

The bearings are a different kettle of fish and are awkward to remove/replace without the correct tools, though not impossible. I've found that removing the cranks and even the chainrings for a thorough clean and reassembly solves most creaks and grinds anyway.

the cranks are sram force cranks, both sides have a hex nut opening and the drive side comes off so maybe I should just try and tap the shaft through, will have a look at this tonight thanks for the info

I also have sram cranks and all you need to do is undo the non-drive side and tap the shaft through with a rubber mallet. they are a 2 piece crank and therefore you dont remove the drive side crank from the shaft.

The "do not remove" refers to the washer, not the crank arm. That's the crank removal ring; as you undo the bolt, it pushes against that ring to pull the crank off.
I had a thought, but it got run over as it crossed my mind.
