As you may now the Ural/Dnepr gearboxes can have oil leaks through the clutch bearing housing of the gearboxes. The reason for that is the bearing housing wich is worn in the interior because of the movement of the clutch bearing:

So I have dismounted the bearing housing from the gearbox, in order to do that the best way is to put a cylinder in the gearbox as a counter force, heating the area with a torch and after that you can extract whitout problems the bearing housing:

So, a turner has machined this part and intoduced inside a cast iron cylinder which is more resistant the then aliminium:
