Clutch master cylinder
Discussion

.... I cannot be sure my 3/16 pipe is original
My S2 has different pipe sizes for the clutch (1/4" pipe, 7/16" union thread) and the brakes (3/16" pipe, 3/8" union thread). The Girling 64676310 (0,7" bore) master cylinder is fitted. I think these are all original. HTH !Thanks Tim, that is helpful. Yours is an S2, 1989 car?
Chris, all I need if the outside diameter of the pipe, that would be sufficient to identify it. Age of car too please.
If you are able to check the union and give me the diameter of the thread and even better the number of threads per inch (tpi) if you can work that out. That will enable me to work out the type of coupling.

whether or not TVR ever used 3/16 pipe it would seem logical, to me anyway, for them to stock just one master cylinder and an adaptor or perhaps a "full up-grade kit", matching master and slave cylinders and flex pipe.....
Meanwhile cheap skates like me will carry on buying Land rover bits off Ebay for a fraction of the cost and making them fit
I agree Mike, I have discussed this with TVR Parts and they are well aware there is no point in stocking anything which is readily undercut by other suppliers.
When we can be absolutely sure of what is needed then they can look at sources to see if they can offer at the same price so we can go to them. You will understand commercial realities: unless they can get us to buy the 'volume' stuff from them (and that would include hydraulic bits)then they will never find it commercially viable to source the more difficult specific stuff like bumper rubbers, targa panel sockets, door trim rubbers etc for us.

Outside diameter is 1/4" Car is 1993 S3 a picture paints a thousand words so here's a few thousand words Chris, all I need if the outside diameter of the pipe, that would be sufficient to identify it. Age of car too please.

No idea what threads these are !!

I agree Adrian, they must do this properly. However there is an issue for them to address and that is whether to stock the exact original (ex Marina) or the 'Lucas' 'replacement' part as supplied to Series 3 Defender/Landrover, which TVR did use later.
I agree with you that they cannot sell 'cheap' parts, they have to ensure they are all to correct spec, but
I can see little point in TVR Parts supplying to old spec if a newer spec part is readily available to owners.
I would not now dream of fitting a Marina master cylinder now we know the S3 is a perfect fit and same performance.
Similarly I wouldnt encourage them to try to supply the old spec SAAB servo as well as the later spec FORD when many cars will have beenm converted by now and those that haven't can readily convert.
It is one of the things we have discussed, during the years without factory support things have moved on and to attempt to stock just original specification parts might well not be commercially sensible. No use stocking parts that we are unlikely to want! Perhaps the same way that supplying original spec bulkhead bearing for the steering column, or indeed original headlamps and bowls, would be retrograde steps. They have a number of areas like this where pragmatic decisions will have to be made.
I would be interested in any objective comments on this from you Adrian or indeed other S enthusiasts.

I've done a couple of sets of hydraulics for clutches and changed the whole lot for Land Rover parts with 3/16 pipe.
It's not original spec, it theoretically makes the clutch a fraction heavier, but if you've lost clutch hydraulics on a euro tour you've got a damn site more chance of fixing it in a foreign land with Land Rover bits than something TVR modified - well that was my reasoning.
Bring on the flames.

Thanks Chris, I have emailed you. Thanks
Adrian, I think that is a very important point. We mustn't forget that the majority of PH S owners are enthusiasts who look after their own cars and are not above 'fettling' a part to fit. That doesnt cover the owners now, or in the future, who want to be able to take their S to a local garage or, increasingly I suspect, a TVR approved garage. That garage wants to be able to look up a part, clearly identified on the web page, order it and expect it to be entirely compatible. That does make the task of TVR Parts more difficult in supplying two 'parallel' markets. However another member has drawn my attention to companies like Rimmers (Triumph/MG particularly) who have successfully dealt with this in their parts listing arrangements. The non-original, or indeed alternative parts, become more relevant the further back we go in the production of the brand. For instance I doubt if TVR Parts will find it viable to arrange the re-manufacture of 'original' Mk1 Grantura parts!

Hi All
The way I look at it is TVR has been left in limbo, left to a few parts suppliers, who have done a splendid job over the years. Many S and other marks have been drawn into home mechanics to save costs and some just want to tinker with there pride and joys.
I don't expect the new TVR people will stock many parts for the S as most of the common bits have been found fitted and written about on the forum.
The body shells are an area that could be made due to accident damage, I think there are people making parts now for our cars, I did read somewhere that the S moulds were lost in German. So if you had to make up a list of bits that are unobtainable where no alternative part has been sourced I think it will be a short list.
