It depends I do not remember if that reindeer carries a double bearing or two bearings, if it is a double bearing to be able to take it out, a indraulic press as well as to put the new one, and for this you should disassemble the complete mass, if double bearing equally you have to disassemble the dough, but those cuvetas can take it out with a ninsel and hammer to put the new ones is not comlicated but loop that falls straight.
