1) Remove the bearing from the rear flange;
2) Insert the two centering pins into the pump body;
3) Replace the seal on the flange;
4) While lining up the holes with the two pins, bring the rear flange and the pump body together;
5) Insert the 6 mounting screws into the slotted holes and tighten to 45 ÷ 55 Nm;
6) Using a mallet, install the bearing on the flange;
7) Install the seeger ring on the rear pin;
8) Install the rear cover or oil pump (together with the connecting joint) back onto the flange;
9) Remove the centering pins.
The MEC 9000/11000/13500/16500 pump is equipped with a system that allows the flange to slide, which prevents breakage if
foreign bodies become lodged between the rotor and the pump body. (Except for version G-GA)
To benefit from this system, it is important to follow these instructions:
Before starting the pump, make sure the rotor has not dropped down accidentally. This can be accomplished by making sure the
cut in the flange lines up with the cut machined into pump body (see figure A).
