FSA MegaExo Crank bolt Lockring Tool alternative

[mr brambles]

I need to change the crank bolt on FSA Omega crank as the numpty I am have sheared the bolt and does anybody know if the Park red/green pin spanner (or any other tool) can be use to remove the bolt as the tool is more expensive than the bolt?

Thanks in advance

Are you talking about one of the pinch bolts or the bearing preload bolt here?

Which bolt have you sheared Mr Brambles ?
The large headed preload bolt, or the 'grub screws' either side of the crank.
Either way, I can't see how the pin tools will help you.

If you understand the principles of the preload bolt, please disregard the following...
If its the large headed preload bolt, it suggests you may have heavily overtightened it, that bolt only requires 'tightening up' to take up any side float and no more. Once you have 'tightened' it to eliminate any sideways movement of the cranks (and when it's right, it's not tight if that makes sense), you then tighten the two opposing grub screws to lock the preload bolt...and therefore the cranks in place.

If you had tightened the preload bolt to the point of it breaking...even had it not broke, your BB would not have survived long at all, you'd be applying far too much side load to the BB.

There is only one bolt that holds it all together and there are no pinch bolts as its a bb30 bottom bracket.

I'm gonna take the bdooly bike to Evans to get a new bottom bracket as it's done 5000 hard miles as the bb is screaming like a banshee and get the bolt done at the same time.

I'm going to look a prize pratt on the Mrs' suspension bso till its sorted.

Ahh, the design has changed then. Hope you get it sorted ok. TBF, I think I got 6k miles out of my BB4000 BB as fitted to standard MegaExo's, they leave a bit to be desired in quality.
