Title: C-spanner for headset
Post by: Bretty on 17 August 2016, 12:35:49 pm

Hi all,

What size C-spanner do you need to adjust the head bearings?

Can you use the one in the tool kit for the rear suspension adjustment? Or will I need to order one? And if so what size do I order?

Thank you!

Brett

I'm not sure of the size but it's a lot smaller than the shock absorber c-spanner

Tap it round with a flat bladed screw driver, set the bearing and lock it up.

What Joe said, I'll add don't tighten it more than a quarter turn to start with!

I bought one off ebay a good while back that you could attach a torque wrench too with an adaptor. The link that I have to the one I bought doesn't work anymore but I think it was a 43mm one. I'm not 100% sure on that. You can measure your headstock bearing to confirm it. Here's a link to a similar one

It's all sorted now thank you! It's a ridiculously low torque on these splined nuts. Literally finger tight, then a couple of taps either way to adjust. Locking nut is not much more. I just worked through the Haynes manual and didn't need a c spanner.

Cheers!
