RogerH Posted May 1, 2019 Report Share Posted May 1, 2019 Hi Dave, the plastercene dimensions should be accurate enough. Roger Quote Link to post Share on other sites
cookie Posted May 3, 2019 Author Report Share Posted May 3, 2019 From the evidence above would people agree that the wrong starter was fitted to the 3A many years ago and that the WOSP replacement should be the later 10 tooth version. Thanks Dave Quote Link to post Share on other sites

The tooth gap on the old and new starter is around 12mm. Hi Peter, As can been seen i my previous picture the ring gear is bolt on and the old starter looks like the one in your middle picture. So i think I'm am safe in saying that the wrong starter has been fitted to this TR3a for many years and we have got the wrong WOSP replacement. I would have thought that the ring gear and starter would have suffered far more than they have, thankfully they haven't. Back to the TR Shop to exchange the new starter for the correct one. Hope you agree. Thanks for all the help. Dave Yes, sounds like you are doing the right thing. cheers Peter W Quote Link to post Share on other sites
