6-2 Replacement of repair parts Replace the pumping unit and the relief unit at the same time. 6-2-1 Replacement of pumping unit 1) Put a special tool on the 12 square nut of the pumping unit and turn it counter clockwise to loosen and remove the pumping unit from the pump. -
Page 29: Replacement Of Relief Unit
6-2-2 Replacement of relief unit 1) Insert a thin plate between the cap and pump to remove the cap. 2) Remove the relief assembly with the special tool. Special tool The special tool can only fit in the outer groove. Never insert the special tool into the inner groove to rotate it, because doing so changes the set pressure. -
