Hi (1972 series 3) Gearbox suffix A I have just had the gearbox out to replace the layshaft bearings. I Split the gear box from the, transfer box, bell housing and removed the layshaft to replace the fore and aft bearings. Re assembled with new gaskets etc and reinstalled. All good so far. Gearbox nice and tight, can select all gears fine. However when I engage high range it now keeps jumping out into neutral. Low range is fine with no problems. The strange thing is that I didn't touch the transfer box other than removing transfer gear to detach the gearbox and then to reassemble the whole gearbox. High / low ratio was perfectly selectable before and all components have been reinstalled as they were before. Thanks for any help...

Thanks for all your help - I bought a 9/16 propshaft deep socket for a tenner of fleabay and these came off very easy with a 12v impact wrench. Once again thanks for all your help.

Many thanks for all the replies - I've ordered a 9/16 deep prop socket and will try that first...

Hi I am in the middle of changing the layshaft bearings to my series 3 swb. I have encountered a problem which I really appreciate any help with. I can't seem to loosen the 4 nuts fixing the rear prop shaft to the transmission brake. It seems that a some time someone has had a go at removing the rear prop as three of the four nuts have rounded / burred and consequently I can't seem to get them undone. The thread or stud projects over the head of the nut so I am unable to weld a nut to them to be able to loosen. This has resulted in me removing the gearbox with the rear prop still attached - however I am now stuck as I am unable to remove the transfer box whilts the rear prop remains in-situ. Anyone have any ideas or experience in dealing with this.... I would be very very very appreciative. Photos below: Many thanks.
