What size is the nut......

[gypo]

What size is the nut going into the back of the clutch slave cylinder, the one for the fluid pipe? I though it was 12mm but the spanner feels a bit slack on it and when i try to turn it i can see im going to round it off if i give it any more?

Most slave cylinder bolts/nuts tend to be 11mm - 7mm for bleed nipples.

Just had a good look round the garage to find a 11mm open ended spanner, it doesnt fit it looks almost as if it 11.5mm? I might try grinding a 11mm spanner tomorrow tilll it fits.

Well done Clartsonly

251 721 477J is definately the right part replacement for the old metal/rubber clutch hydraulic pipe. I fitted it today.. no problem.
Give yourself a big pat-on-the-back.

A tip for seperating the flexihose from the front line pipe without damaging the front pipe. File an 11mm spanner to 11.5mm and use that with a little persuasion on the front pipe union, if you use a 12mm it will round off and you will probably have to replace the entire front pipe.
Dont turn that union just hold it and unscrew the flexihose from the union.
That done... if the union is seized on the pipe, use a blow lamp on it and allow it to cool. It should free off. It needs to be free to screw into your new replacement part.
Well it worked for me.Richie

cheers for the info, when you say unscrew the flexihose from the union do you mean, leave the fitting in the old slave cylinder and unscrew the plastic pipe off it then once the cylinder is off the van warm it up and get the fitting out?
