Big nuts - transmission

Greetings. Does anyone know the size of the big nut on the output shaft on a BW12 - the one that retains the tailshaft coupling? I have a leaking seal that I might tackle over the Christmas break. Regards. Paul

The one I have in the shop from my 72 XJ6 is 1-1/2"

Hi Mike, thanks. Will need an impact driver to remove, I expect. Paul

to undo pinion nuts, which are usually too tight for my impact guns, instead I use a trolley jack under (preferably) 3/4" breaker bar. The car is only lifted a few inches

R&R leaking pinion seal can be done very quick, including on a Jag, I have some other tricks for that job

Thanks Tony. I have a 3/4" breaker bar - I will keep that method in mind. Paul
