Tool for EBB - please direct me ...
« on: April 28, 2016, 05:24:04 PM »
Hello All.  Long time member, first post (I think!).  I do recognise a few names from over at the CTC Forum...

Does anyone know the correct tool I'd need for adjusting EBB please.  The EBB in question is as per this:

http://www.sjscycles.co.uk/eccentric-bottom-bracket-insert-fits-raven-tour-mk1-sport-tour-only-prod11656/

The only tool I can find on the SJS shop is this:

http://www.sjscycles.co.uk/thorn-3-in-1-bottom-bracket-eccentric-tool-for-73-mm-shell-raven-bikes-prod12076/

Which I am sure is not the correct tool.  Please advise...

Thanks Chaps!

Hi
Sorry for resurrecting this old post. Does anyone know if there's a way of adjusting these old Raven eccentric BBs without this specific tool? I.e. can I bodge it with standard tools or should I just cough up for this specialised spanner?

I did a deep clean of all moving parts on my Raven yesterday.
With the x2 bolts removed I was able to slide the EBB across and then grease it. The previous small bolt point indentations were easily visible.
It was easy to reposition.

I take it your EBB doesn't move easily?

Perhaps a large screwdriver blade end could be used to nudge one of the indents? Or a wooden wedge?

Let us know how you progress.

Best

Matt

Thanks Matt, very helpful.

Ended up inverting the bike, removing BB bolts, spraying a bit of lubricant in the holes and then knocking the BB sideways with a rubber mallet which mobilised it. Then tapped a narrow bit of wood in one of the notches to rotate it to tension the chain. Might get the special spanner for next time though.

The notched type looks like a pretty standard C spanner, the Thorn version isn't bad value, but you might find one locally in any decent tool shop, or if you're sure of the size a bargain one on Ebay. 
I'm glad they didn't stick with that design, by the time I bought a MkII it'd changed to the two hole design.  A pin spanner is the correct tool for that, but it's as easily done without by sticking a couple of screws in and using any thin spanner.

Next time you 'tap' the EBB out, apply some grease.
Pleased you managed with the rubber hammer.

Thanks Matt and PH for the tips. Will make sure to give a generous dollop of grease.  :D
