Mavic 670 hub tool

[Ghs4th1987]

Guys, I need a hub dust cover removal tool. The 6 pin type looks like a block remover.
My cpx30 rear wheel needs new bearings, plus I have a bottom bracket that I need to do the bearings in.

I understand it is part 670.

Thank you.

Good Luck!

unless the alloy adjusting disc is loose that plastic tool will just fail big time. Are you wanting to replace the bearings in a Mavic BB? if so finding a replacement will be near impossible as it was a special ( std size but with the outer diameter reduced)

where about are you located?

Re:

It's French engineering.

It's the 1980s. The design team is in full discussion in a room hazy with the smoke of Gauloise.

'You have messed up the design of the hub....'
'why?'
'The earlier proposal needed a special tool that no one had, the metal was the wrong grade, and it was far too complex....'
'yes, but I made it simpler and more robust....'
'You fool! We are MAVIC!! No one makes a crap design simpler and better on my watch!!!!'
'Sorry....I'll add complexity and lack of reliability to it.....'
'Perfect'

Nice film but they didn't fit the 2 plastic washers to the BB. lovely BB's. I have a few in my box of bits and some spares and tools for most Mavic parts.

Thanks for the info. I'm really keen to get the tool, if I can't find one it will be a new hub, I have a couple but it would be a shame to go to that length when the tool is floating around somewhere.

Re:

I had one still on in the cardboard/plastic wrapping, hadn't used it in 20 years, put it on Ebay & got £50 for it! I was amazed. The machining of the pins is pretty complicated, they sort of sit on top of another pin ...

We should all chip in to a collective retrobike toolkit, that we can dip in to when we need that obscure tool that can no longer be found anywhere.

Re:

Quite agree. I have the mavic ssc headset spanners if required. Plus a few chain whips!
If your fixed cup is stuck I have welded a big socket onto one and removed with a long bar. Happy to offer this to frustrated middle aged men trying to rebuild their
Bikes from the 80s. With no or little paint damage.
