–  Before assembling the crown of the differential, consult section for Identification initials, assignation of groups, reductions, amount for filling → Chapter.
–  Carefully clean the surfaces of contact for the crown of the differential and of the differential box. Use a wire brush and a scraper. Never use emery cloth or sandpaper. The surfaces for contact must be completely free from oil and grease.
   
–  Check the position for the assembly of the crown with regards to the differential box.
Position for assembly: The inner groove -A- in the crown of the differential must be facing towards the opposite side to the housing for the differential side gears.
–  Heat the crown of the differential with the electrical blower -SAT 1416- to 150 ºC. Check the temperature with the digital thermometer -SAT 4002-.

t  If both parts lock or get stuck on being assembled, interrupt the assembly process and begin again.
