Rear Axle seals - MM Type
Both my rear oil seals have been leaking so will need replacing. May as well do the bearings while I'm at it. I have the early type MM split Case rear axle. Any tips on removing the half shafts and bearings? Manual recommends a special tool, what should I use? Slide Hammer? also, how to remove the split collar without damage and how to get the bearings on and off the half shaft once out. Pics attached. Cheers

Re: Rear Axle seals - MM Type
David,
That is exactly the same axle set-up as on my MG TD and the lads on the T-Series forum have documented this procedure very well with photos. The workshop manual description is not detailed enough.
Read through this and it will solve your problem:

You will require the slide hammer which you can make up yourself-see mine below which is made from an M10 tensile bolt and a chunk of metal as the slide+adapter to axle thread.
As far as I know you will need a BSF/M10 adapter to fit your axle. Both half shafts have a right hand thread.
Some get away without the slide hammer by tapping the bearing housing free, then using the drum as a slide hammer. I am not advocating this method.
It is described towards the end of this thread.

Re: Rear Axle seals - MM Type
Thanks so much Declan. Appreciate the help
Sounds like getting the bearing off the half shaft is quite difficult. I may just leave the ones on there. I'm not aware of any noise from them

David,
A bearing puller like this should do it.
Some of the guys use a sealed bearing and this further reduces the risk of oil leaks.

Thanks Declan
But where's the rest of the shaft?? Is there a hole on the bench?? Bit confused
I might just end up taking the shafts to a local garage and getting them to replace the bearings with a press.

David,
That is just a photo showing how to remove a differential pinion bearing for reference-just to illustrate what type puller you could use. That is not a half shaft and there is no hole in the bench-at least the last time I looked.
