RENAULT KANGOO DIESEL HYDRAULIC ADDRESS PUMP

I am looking for, as soon as possible if you can the disarmament manual, and arrangement of hydraulic liquid leaks of steering pumps in the Renault Kangoo, diesel full. Or someone who knows how to do it at home, and if possible with what type of tools should be counted. I have some knowledge of mechanics, so everything will be very well come. It has liquid losses on the sides. It started with a few drops and now loses a lot !!
