DesNoble Posted December 1, 2022 Report Share Posted December 1, 2022 Does anyone have an oil filled pressure gauge with an extension adaptor so that the car can be driven with the gauge in position. It's an A-type overdrive for a TR3A. Thanks. Des. Quote Link to post Share on other sites

DesNoble Posted December 2, 2022 Author Report Share Posted December 2, 2022 Thanks Tom. I'll give them a try. Des. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted December 2, 2022 Report Share Posted December 2, 2022 (edited) Des, have just picked up on this. I have a new 0-600 psi oil filled gauge with a 1/4 bsp male connector. The accuracy I am able to check as I do not have access to static dead weight testers these days. I also have the Churchill Tools auto gearbox pressure gauge set with flexible hose, adaptors and gauge. The adaptors do not fit the TR overdrive and the gauge is 0-300 psi. Plus All are what looks like 1/8 bsp threaded. I am tracking down an adaptor 1/4 to 1/8 to fit the 0-600 gauge to the hose, then all I have to do is make/buy a fitting to go in the overdrive that connects the overdrive and the flexible hose. With all this done you would be welcome to borrow said kit. PM me if you are still seeking. Peter W Edited December 2, 2022 by BlueTR3A-5EKT Quote Link to post Share on other sites
DesNoble Posted December 5, 2022 Author Report Share Posted December 5, 2022 Yes Peter I'm looking at the contact that Tom gave me above, but as yet I haven't bought anything, So yes I am interested in what you have. My aim is to have a tester which I can attach and use while driving the car or at least static with the prop disconnected. Regards. Des. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted December 5, 2022 Report Share Posted December 5, 2022 Des, I have ordered an adaptor to fit the gauge but do not have one for the overdrive yet. Any one any idea what the thread into the overdrive is? Quote Link to post Share on other sites
Drewmotty Posted December 5, 2022 Report Share Posted December 5, 2022 The thread is 1/2” unf. You should be able to pick an adaptor up for a quid in the tea fund at your local hydraulics specialist. I have a 1/4” BSP to 1/2”unf adaptor here if you are stuck. 1/4”BSP has a internal cone to take a hose fitting and the 1/2”unf is flat faced. I counterbored mine (just with a drill) to better replicate the overdrive cap. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted December 6, 2022 Report Share Posted December 6, 2022 Thank you for the thread s sizes. I will endeavour to create an adaptor 1/2 unf to 1/8 bsp with a recess. Quote Link to post Share on other sites
DesNoble Posted December 6, 2022 Author Report Share Posted December 6, 2022 One thing. The cap on the gearbox where the plunger for the O/D selector is retains the spring. Will your adaptor retain the spring at the correct position. Des. Quote Link to post Share on other sites
DesNoble Posted December 12, 2022 Author Report Share Posted December 12, 2022 Peter, I've just ordered a gauge and adaptor from Dave at O/D spares. Thanks for the offer of yours and conversely if you still have trouble sorting out yours when I've got mine sorted you are welcome to borrow mine. Des. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted December 12, 2022 Report Share Posted December 12, 2022 Sorry for slow assistance I am still waiting for the post to deliver the required adaptor. Quote Link to post Share on other sites
DesNoble Posted December 13, 2022 Author Report Share Posted December 13, 2022 Not a problem I was probably feeling a bit like a bit of shopping therapy! Quote Link to post Share on other sites
