DAKOTA 2002 TDI 2.5 HYDRAULIC ADDRESS PUMP

Hello friends, I need help, I have a Dodge Dakota 2002 Diesel Motor 2.5 TDI and I break the axis of the hydraulic direction pump, this axis joins the depressor the hydraulic pump and the air conditioning, can anyone tell me how the motor block pump is separated ??? The axis passes from one side to the other from an ear of the block and is not seen as disassembling it.
If someone has any information would be very helpful, thanks.
