If you can position your lever against the underside of the chassis right hand main rail, then as you try to undo the nut it will force the gearbox downwards against whatever you are using to prop the gearbox up. ( right hand looking from front to rear ). That should do it. Cheers, Dave.

I have 3 makita drills  but dont know about their impact wrench ,, not to be confused with a impact driver which is normally aimed at screws not 32mm nuts

Well, here's the tool I made. It made very light work of it in the end. Popped the old seal out really easily too. New one went in square and used a piece of pipe to carefully knock it in.  Took it out for a spin..to check...came back and the bloody thing is slightly weeping oil out....  
I'd cleaned up the flange ok..could see where the old seal was sitting on the flange and it looked smooth without nicks in it....not sure what's gone wrong..it's a fairly simple procedure..

I had a similar experience with Toby, many years back, when he belonged to my brother. The O/D rear seal was leaking so we replaced it... and it still leaked. Some months later, my brother declared that it no longer leaked but given his mechanical skills I suspect that was because it ran out of oil (the O/D had never worked so the obvious symptom wouldn't apply). When I rebuilt the whole shebang some years later to go in Felix (the other brother's Mk2 Spit) I managed to get a good seal.

I'm hoping it may settle down..bed in...   When the oil is hot and thinner that's when it weeps. The seals seem to be a standard universal part 513231.
I did have a simialr thing when I did my crank front seal that sits in the timing chain cover. Went through about 5 and it still leaked..until I bought a full metal jacket type one from Barnwell. been good ever since.
I shall monitor and potentially buy another and try again..bit of a pain but I now know it's only an hour or so job

glad its off...on   off think weve all been there from time to time

i would burnish the coupling with some 1200 grit it may show a wear line,


skf and others make wear sleeves , this is a very tin tap on tube to repair worn journals  and uses same seal .

on production in the 80s we fitted them a std to all our axles so its not a bodge .so repairs could be done in later life.

do check the OD breather and the small hole in the gearbox top cover ( under the selector rod casting are open and working)

I'll have a look, it's that black thing on top of the OD.  

Wish I'd burnished it now before putting it all back...too keen. It looked perfectly smooth, with a mirror like finish. I did wonder though if the new seal lip was in a different place to the old and may sit further out..in which case it was more cruddy further out?

I've just taken it out for another spin and it seems to be good now. Any recommendations on where to buy sleeves?
