Moliver Posted December 28, 2022 Author Report Share Posted December 28, 2022 Hello All, After a few weeks I can report back, that I have successfully managed to get an overhauled TR4 box with OD which I have successfully installed today. So far installation went smoothly. Next steps will be checking the fit of the gearbox tunnel. I have noticed the position of the speedo drive and am wondering if I should be concerned about interferrence with the tunel ? Any advice on this?

Nobbysr Posted February 22, 2023 Report Share Posted February 22, 2023 Hi Oliver You should be OK once the angle drive is fitted to the brass fitting , im guessing that you might not be aware that you need one , if you dont have one they are available new at i think about £150 cheers Steve Quote Link to post Share on other sites
Lebro Posted February 22, 2023 Report Share Posted February 22, 2023 (edited) Should not need an angle drive on a sidescreen, the cable passes through a special grommet which also covers the base of the handbrake Click on to enlarge Bob Edited February 22, 2023 by Lebro Quote Link to post Share on other sites

Z320 Posted February 23, 2023 Report Share Posted February 23, 2023 (edited) Good advice and photos, thank you Bob. TR friend if mine did this on his TR6 too, with the cable on the floor / below the carpet. A long speedo cable is needed this route.

Drewmotty Posted February 23, 2023 Report Share Posted February 23, 2023 I’d certainly dump the angle drive if you don’t need it. If you haven’t got one it can’t go wrong. Quote Link to post Share on other sites
Nobbysr Posted March 3, 2023 Report Share Posted March 3, 2023 (edited) Interesting, my angle drive is a nice fit and uses a shorter speedo cable which does fit nicely behind the rubber gaiter. The cable is too short to reach without the angle drive. I do service mine every 4 or 5 years with a clean and a regrease after years of experiance with them running GT6s . The newer iangle drives dont have the peened cover so its possible to service it and repair if the cable end comes adrift . The gearbox i have is a triumph 2.5 casing and the overdrive is triumph 2.5, the gears seem to match tr4a and i have up rated some parts when i rebuiult the box 18 months ago. I am guessing that over the years there have been a number of Manual to Overdrive converstions with later TR boxes/Saloon boxes, fitted with O/Ds with angle drives. Never occoured to me that the side screen works manauals dont detail their use for sidescreen cars ... learn something every day Edited March 3, 2023 by Nobbysr Quote Link to post Share on other sites
