The electrical connector block that has a plastic body with brass fittings. Wire in one side, another wire out the other. Ebay here Remove one of the brass connectors. Open one of the grub screw holes to fit the heater valve pin. The operating cable goes in the end and locked with the remaining grub screw. TRNiall posted this about two years ago. Roger Love it!!! That is a bloody clever idea!!!! Thanks to Roger and TRNiall!!! Rich Quote Link to post Share on other sites
Waldi Posted April 5, 2019 Report Share Posted April 5, 2019 I looked for that electrical connector block too. Nowadays the brass is replaced by a cheaper pressed steel version. I could not find any large enough with brass inserts. if you lokk closely in de detail in de ebay offer above, you can see it is not brass. That’s why I made my own.

Regards, Waldi Hi Waldi, if you visit your local electrical supplier they will have quality brass connectors of all sizes. Ebay sells rubbish because people pay peanuts.

Waldi Posted April 5, 2019 Report Share Posted April 5, 2019 Hi Roger, I did just that, and also asked my peers, since you will need the slightly larger ones, but old-fashioned with brass inside: nothing. So I made my own, not too difficult, the 3rd one I made was acceptable:) Time required: 1/2 hr to fabricate + 3 hrs searching the www and local stores. Waldi Quote Link to post Share on other sites
RogerH Posted April 5, 2019 Report Share Posted April 5, 2019 Hi Waldi, so cheap repro parts is alive and well and outside the TRiumph family. Roger Quote Link to post Share on other sites
Waldi Posted April 6, 2019 Report Share Posted April 6, 2019 Modern times Roger. we have a coffe grinder, think it is 40 years old (think it came from my grand mother), still going strong. We have bought 3 new mixers in the last 5 or so years, they simpky give up after a couple of years. Yes, many products were better 30 years ago. Waldi Quote Link to post Share on other sites
jogger321 Posted April 6, 2019 Author Report Share Posted April 6, 2019 Ok getting there...I cleaned the thread of the tube and sprayed some wd40 on it where the Four seasons screws into and also used PTFE tape as suggested and have now managed to get it in ok Does anyone have a RHD car with it fitted that could post a picture of the complete engine bay so I can see the angle that they have it in relation to the rubber heater pipe that it attaches to and the cable (how far screwed in) Did people manage to use the existing inner and outer cable as at the moment it seems slightly short (might be because I have it screwed in too much a 1/4 of a turn or 1/4 too little??) Many thanks Quote Link to post Share on other sites
Waldi Posted April 7, 2019 Report Share Posted April 7, 2019 On my LHD car the original cable did not need any modification. I think LHD or RHD would not matter by the way. I oriented the valve such that the hose and cable lined up nice. Waldi Quote Link to post Share on other sites
RogerH Posted April 7, 2019 Report Share Posted April 7, 2019 (edited) Hi Jogger, the valve points back apprx 45 degrees. I'll grab a photo later this morning. To gain max benefit from the lighter action of the new valve it is worth considering swapping the position of the controls inside the car. The valve is operated from the left side of the consul. The flap is operated from the right hand side of the consul. Both cables have to do a tight 'S' bend to get to their destinations. So with then swapped over they have a virtually straight run. This also means that you will need to shorten them. Thus you will have plenty of cable to play with. Roger PS - I've just realised this is the TR6 forum - the cables may already have been swapped over. Edited April 7, 2019 by RogerH Quote Link to post Share on other sites
cvtrian Posted April 7, 2019 Report Share Posted April 7, 2019 (edited) Hope this helps, it's a great improvement on the old valve! Regards Ian PS The cable with the blue insulation is a secondary bonnet release cable, another mod well worth doing! Edited April 7, 2019 by cvtrian Quote Link to post Share on other sites
Waldi Posted April 7, 2019 Report Share Posted April 7, 2019 Mine has the same orientation as Ian’s. Waldi Quote Link to post Share on other sites
jogger321 Posted April 7, 2019 Author Report Share Posted April 7, 2019 Hi Ian & Waldi thanks for that info....Ian that picture is extremely helpful...Just wondering what your arrangememt for attaching the cable to the new valve was as its not completely clear in the photo Thanks also for suggesting a secondary method of opening the bonnet...I have fitted the moss emergency arrangement ta Quote Link to post Share on other sites
cvtrian Posted April 8, 2019 Report Share Posted April 8, 2019 Hi jogger321 I crimped a ring terminal to the end of the cable, then slid a section of red plastic tubing over the rest of the actuating stem, and to prevent it sliding off, used a stem washer. You are only down the road from me (I live in Evesham) so if you fancy meeting up for a MK1 eyeball, let me know. I've got plenty of that red tubing!

ianfox Posted April 19, 2019 Report Share Posted April 19, 2019 Pardon my ignorance, but I'm assuming these valves are an improvement on the standard configuration? Is the effort to operate them less because of the range of movement? and lastly, is there a source/reference number for these? cheers Quote Link to post Share on other sites

The operation is via the same cable and is much easier to operate. It is generally known as the Everco heater control valve, part number 74648. Stan Quote Link to post Share on other sites
David007 Posted August 7, 2021 Report Share Posted August 7, 2021 The thread in the head is a 3/8 18 tpi thread. The thread on the original valve is 3/8 20 tpi The four seasons valve is 3/8 18 tpi that is why it is tight and will only go in a little way. The way round this is to use a 3/8 18tpi 2 1/2 " nipple and coupling then the 4 seasons valve will screw in all the threads are the same. Quote Link to post Share on other sites

Bfg Posted August 8, 2021 Report Share Posted August 8, 2021 ^ mine went in fine after I cleaned the threads. Likewise I used PTFE tape twice around the thread. But then, because I dislike the look of the adapter piece of plumbing pipe and also the valve sticking up so high, I screwed mine directly into the cylinder head. I removed the rocker cover to give me clearance to screw it in, and I did have to gently ease it over the cylinder head stud (for the last two turns) and that gently bent the pipe fitting upwards a few degrees. Being pressed steel it took that very nicely, whereas a casting would have cracked. I'm pleased with it tucked more neatly in there and the heater pipe being a smoother run. Previously with the original valve, sitting on the elbow adapter, facing backwards the heater hose was chafing on the battery clamp, now it is probably 3" lower and well clear. Pete. This is why I changed mine. Quote Link to post Share on other sites
ed_h Posted August 9, 2021 Report Share Posted August 9, 2021 (edited) Pete, I'm with you in thinking the original valve mounted on that angled stalk looked awkward and gangly. I put mine on a shorter adapter that also made it vertical. It's a trifle, certainly, but I like it and it kept me busy for a few hours.
