Willie Posted October 29, 2020 Report Share Posted October 29, 2020 Hi All, I would appreciate feedback on whether or not my tacho cable is fed the wrong side of the master cylinders bracket and, whether the cable is too long. A few photos attached to illustrate. If too long, where do I obtain the correct length? Best wishes Willie Quote Link to post Share on other sites
Willie Posted October 30, 2020 Author Report Share Posted October 30, 2020 Reworked route to obtain smoother line. I improvised a support above the rocker box using a piece of stainless welding rod. No interventions! See additional shots Best wishes Willie Quote Link to post Share on other sites

Willie Posted October 30, 2020 Author Report Share Posted October 30, 2020 Interesting, Stef. It appears 49.5" is the standard length. Revingtons actually sell a 51" cable! I'll do an approximate measure tomorrow and see if it fits spec! Have you fitted a shorter cable? Willie Quote Link to post Share on other sites
Geko Posted October 30, 2020 Report Share Posted October 30, 2020 Appears you got a speedometer cable 78" while it should be 48" Quote Link to post Share on other sites
Colin Symonds Posted October 30, 2020 Report Share Posted October 30, 2020 I have recently changed the tacho cable on my 4A, and opted for the 51" one from Moss, I believe it's listed for the TR3. Quote Link to post Share on other sites
mikeh Posted October 30, 2020 Report Share Posted October 30, 2020 Hi Willie, The Moss catalogue shows the TR4 RHD tacho cable as 48" in length and this is what I've recently fitted to my own car. The part number is GSD111 and its used on many other cars of the same era so is widely available. You'll find that this will fit much better than your present cable which looks to be quite a lot too long. Hope this helps Regards Mike Quote Link to post Share on other sites
Willie Posted October 31, 2020 Author Report Share Posted October 31, 2020 YES! I used the wife's tape measure and it is at least 60" to the bulkhead, so actual length is greater. The debate is now.....48" standard or 51" as recommended by Revingtons. Should the cable be fed straight from the bulkhead under the master cylinders? I am hoping for opinions on that too!!

Willie Posted October 31, 2020 Author Report Share Posted October 31, 2020 Just had a thought - might I have TWO speedo cables fitted currently? Does a length around 66" sound about right? Willie Quote Link to post Share on other sites

Best wishes Willie Hi Willie, As mentioned, I recently bought GSD 111 (48") as a replacement and it fits fine, although I must admit I hadn't spotted that Revington actually list GSD 113 (51") as their recommendation. The 48" version doesn't seem tight in any respect so the extra 3" is probably neither here nor there really and either cable will be a big improvement on what you've got at the moment. The route, at least as my installation, is between the rear of the rocker cover and the battery, with a supporting p-clip on the driver's side battery clamp, and then down between the master cylinders to the bulkhead grommet. It should fall fairly naturally to this route as you don't want any tight bends or real tension on it. Hope this helps Mike Quote Link to post Share on other sites
Willie Posted October 31, 2020 Author Report Share Posted October 31, 2020 Thanks Mike. Exactly what I was looking for! I'll post the final shot when I receive the cable. Best wishes and thanks to all contributors Willie Quote Link to post Share on other sites
Geko Posted October 31, 2020 Report Share Posted October 31, 2020 FYI, the cable routes to the left side of the hydraulic bracket then above the steering column coupling then between the bulkhead the cylinder head. It fools the edge of the bracket so you may want to add a rubber band on that location. Quote Link to post Share on other sites
Willie Posted October 31, 2020 Author Report Share Posted October 31, 2020 Thanks Stef. That's very useful. My long cable went that route, but in big loops! Best wishes willie Quote Link to post Share on other sites
Geko Posted October 31, 2020 Report Share Posted October 31, 2020 (edited) on your first pics it routes to the right side, it should go to the other side - that of the steering column (Left and Right are conventionally considered when you're seated in the car ) Edited October 31, 2020 by Geko Quote Link to post Share on other sites
Willie Posted October 31, 2020 Author Report Share Posted October 31, 2020 Thanks, Stef. I did wonder if I was interpreting correctly - viewed from front or rear. I am clear now! Many thanks Willie Quote Link to post Share on other sites
Willie Posted November 5, 2020 Author Report Share Posted November 5, 2020 AND FINALLY.... 51" cable from Neil Revington fitted. See final shots incorporating advice given here. Rev counter is steady now [waved about a bit before!!]. A big thank you to all contributors. Quote Link to post Share on other sites
