How do i separate the tub on the Bosch classixx?

hi, i replaced the bearings on the same washer (2yrs ago and going down again).
you have to strip the washer down, and eventually lift the tub / drum out from from the top.
the tub splits into 2, if i remember correctly there were a series of 10mm studs connecting the two halves.
once split you will need a new "large" o ring that seals the two 1/2's of the tub.
took some time but saved myself a fortune, most repairers said they could not do the job ????
