Default Rear hub bearing mod

I have just done the second bearing repair mod for my spare 33 rear end.
This fixes the worn bearing area in the hub and on the axle area also.
I machined the hub out to 82.5 mm,then shrunk in a sleave,bored that to 80mm.The hub was easy to machine out after I used a new insert on the boring bar. BUT it is very hard.
machine the axle OD down to 50mm and press on the bearing inner.
The bearings are two roller ones with a total load capacity of 9.6 tons each side.and a limiting speed of 9500rpm ,so should be safe there.
Only draw back of this,I have to remove the brake drum from the hub to machine it as my lathe is not quite big enough to do it with it on.

And ,thanks for fixing the add photo part, Ryan.
