What has happened is the PO rebuilt the box but did not leave suffcient clearance for the roller on the input shaft. They have rubbed on the thrust washer and damaged the hardening on the output shaft. The symptoms were in neutral with clutch out there was a rumble from gearbox, push clutch in the noise would stop.
I hope to use the output shaft from a Hillman Hunter as a replacement in my own gearbox. The Hunter gearbox does not appear to be a straight swap item as the input shaft is shorter than the Jensen, this means I will swap over all the gears and layshaft into my own gearbox to retain normal Jensen ratio's.
For Mark Rosenbaum who seems to like collecting data on car things, the Jensen gearbox has the following numbers cast into the outside of the box
U
71981060
4DA 21055
11 F 4
The Hillman Hunters ( 1978 registered ) has
U
15M 7 A ( not actually an A but a triangle )
71981060
More photos to follow if I have success in the rebuild.
