IMPORTANT: Before proceeding with any re-fitting, replace the gaskets of the opened parts.
3.8.1 REFITTING OF THE BACK
BALLAST SERIES 3500-4500-6000-7500-9000-11000-13500-16000
1) Remove the bearing from the rear flange;
2) Insert the two centring 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) Insert the seeger ring into the rear pin with the compensation ring;
8) Install the rear cover or oil pump (together with the connecting joint) back onto the flange;
9) Remove the centring pins.
The BALLAST 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).
