David B2 Posted May 9, 2023 Report Share Posted May 9, 2023 Hello, Stripped the gearbox and found I could probably do with a replacement main shaft. The input end of mine has suffered a bit. See TR4A threads. Anybody out there with one, possibly no longer needed following their upgrade to add an overdrive gearbox. Thanks, David B, Sevenoaks Link to post Share on other sites
