Andy Moltu Posted September 4, 2023 Report Share Posted September 4, 2023 Been sorting the overdrive which was playing up - solenoid knackered so got the lovely job of taking the tunnel cover out to sort. I noticed that the screw for the solenoid stop - the one you adjust the gap on isn't correct. (Too short and no lock nut) Not currently available from the regular suppliers but a set screw and a nut should suffice. Anyone know what the thread is? Quote Link to post Share on other sites

james christie Posted September 4, 2023 Report Share Posted September 4, 2023 (edited) My sympathy with your plight, Andy. About a month ago I finally resigned myself to sorting out intermittent overdrive operation and narrowed it down to what I thought was an electrical problem at the solenoid. However I do object to the hassle of removing the tunnel cover for such a small job - even if I have fitted Rivnuts. So I set too with a saw and cut a neat (well, I think it’s neat) access panel in the cover in the right place and replaced it an aluminium plate using self tappers and some some non setting mastic to ensure it is watertight. Wonderful result. I now almost look forward to the next solenoid problem ! Oh and the solenoid problem was the rubber boot dissolving in a minor oil leak and crumpling up. A cinch to replace now. james Edited September 4, 2023 by james christie Quote Link to post Share on other sites

Andy Moltu Posted September 5, 2023 Author Report Share Posted September 5, 2023 No that's one of todays jobs when I replace the solenoid. The allen screw is currently NCA which is the reason for the thread size query. Quote Link to post Share on other sites

The allen screw is currently NCA which is the reason for the thread size query. My guess is 10-32 unf. That was the grub screw I screwed into my TR2 some 40 years ago. My current overdrive came with a rubber buffer fitted. That has its own problems. It went goooey and the solenoid piston stuck to it and caused the solenoid to burn out… Quote Link to post Share on other sites
BlueTR3A-5EKT Posted September 5, 2023 Report Share Posted September 5, 2023 (edited) Overdrive Repair Services offer the plate with the stop screw inserted. Worth ringing them to ask if you can have the screw and nut as spares. https://www.overdrive-repairs.co.uk/product/a-type-tr-solenoid-mounting-plate/ or ring Pete Cox as they dabble with gearbox and overdrive https://petecoxsportscars.co.uk/ Edited September 5, 2023 by BlueTR3A-5EKT Quote Link to post Share on other sites
Andy Moltu Posted September 5, 2023 Author Report Share Posted September 5, 2023 Popped over and saw Dave Twigger at Overdrive Spares in Rugby and all sorted. Combined the trip with a test run in the Stag after a coolant flush and antifreeze change. Must have felt brave in 28 degrees. I was hotter than the car! Quote Link to post Share on other sites
