Paul Rear Mech

[Alex3795]

Hi,
I'm currently refurbishing a paul rear mech, its all come apart relatively easily less the last bolt, see photos.
Has anyone got any advice or previous experience with this?
I don't want to force it and roll the edges of the bolt, if loctite has been used is there a solvent to help dissolve it?
Cheers,
Alex

Ok mate hope you dont mind have you got pics of the procees and pics after also what are you planning now stripped intrested as i might need to do this cheers can you not twist the whole thing instead of the bolt i suppose it depends what you doing the loctite will need melting so either heat hair dryer blow torch or solvents could try boiling water

Simply stripping to re-anodize. The mech comes apart very easily, (apart from this last bolt) all you need is a small punch and screrw driver. The key is not to scratch the aluminium. Once disassembled it's a case of removing existing anodizing, carefully filing out any gouges, and then polishing up.

It's currently sat in petrol to soften any solvent and then will try applying some localised heat.

Cheers

Heat on the cage should do it as it will soften any compound and expand the outer section.
You can cool the bolt while you're heating the cage with a damp cloth and wetting the knuckle.
The tool interface is too small for the size of thread, but they probably expected it would be disassembled every year and retorqued to spec

With a bolt exposed both ends like this you can adapt a large vice into a clamp, fitting a driver bit into the Allen head and a spacer the other end.
This ensures the tool can't cam out.
