One of the last things stopping us getting the van driving again is the clutch.

is it not metric? I run a supercharger and I don't care the TB is on the wrong side.

I,m confused (easily done !) you say a 1/2 inch NPTnpt is bigger than 11/16 NPT ?

I think its M12, but with a finer pitch than the M12 bolt you tried to screw in. On 28th Aug, 2011 Kean said:

As per Joe, The yellow band master cylinder I'm installing on the Mini is metric on both threads (M10 and M12) but the M12 is X 1.00 pitch. So metric fine but not even the usual metric fine... For M12, Standard ISO (coarse) is X 1.75 Usual fine is X 1.25 but ISO 724 allows for X 1.00 as well. Schrödinger's cat - so which one am I ??? |

so it's either a custom braided hose or the mini master cylinder then. I'm not sure if the mini one will fit - I think it may hit the servo.

get a hose made with a banjo at each end, then you can just swap the bolt and washers? On 28th Aug, 2011 Kean said:

Or alternativly... If I got a correct M12 male break pipe fitting, put it on a short length of brake pipe with a 3/8 NPT fitting on the other end I could use the standard mini braided hose.

Yes, the conversion kit quoted in my master cylinder box was a genuine rover pair of pipes to convert the metric (yellow band) master cylinder to plumb into a UNF (black band) installation. I just bought the new metric unions from DSN when I called in to buy the master cylinder. (except it's 3/8 UNF, NOT NPT at the other end......) Schrödinger's cat - so which one am I ??? |

I think I'll get a custom braided hose as Joe says. If I take the orginal fitting from the old master cylinder they should be able to match it up...

probably a daft question, but would it be possible/advisable to drill and tap the old union to take the 3/8 fitting?? On 11th Feb, 2015 robert said:

If you mean drill the centre out of the old M12 union and tap it 3/8, it is theoretically possible. With the very fine X 1.0 thread, the thread root diameter of the fitting is ~10.8mm and a 3/8" UNF thread tooth diameter is ~9.6mm so you would have a 0.6mm thick sleeve carrying the load. Take manufacturing tolerances of the M12 thread and the quality of a hand tapped 3/8 thread it could be as little as a 0.4mm thick sleeve. Mathematically a 0.4mm sleeve would easily carry the load but in practice it would probably shear when you were tightening it. I would NEVER consider such a practice for a brake fitting but as it's only the clutch...... Edited by Rod S on 20th Dec, 2009. Schrödinger's cat - so which one am I ??? |

Well. I have a nice new shiney braided hose with a 3/8 UNF banjo fitting on one end and M12x1mm banjo fitting on the other end. It's all bolted in and looking lovely, but... the M12 banjo bolt is 6mm too long.... :$

I had thought about the washers, but wasn't sure if it would seal well enough - 6mm will be closer to 5 ot 6 washers.

Stick a bolt on first, then chop it down. Remove the bolt, and it tidies the thread as it screws off.

m12x1mm bolts arnt particulry common though, if it were for a customers car i'd cut the bolt down and use a 1.0mm pitch thread file. if it were my car id just throw in a few extra washers. turbo 16v k-series 11.9@118.9 :)

Cut it down, Andy, you know it will look better and always aggravate you if you stick a load of washers in there.
