Xantia - Help Correct assembly of the hydraulic pump

Post by lancia58 »

Hi
Recently I replaced my alternator. In order to remove the old alternator the mechanics detach the hydraulic pump. Now when the car is stop and I engage the gear to drive position a rattle sound is heard from the alternator side, while in neutral the rattle sound is not heard. When the rattle sound is heard and I touch the bracket that the metal pipes that are plugged onto the hydraulic pump are attached to ( it is over the alternator ) I can feel knocks that in my opinion are the source of the rattles.

I checked out how the Hydraulic pump was reattached to the bracket and compare it with the match drawing from the “Citroen service “ web site and found some
mismatches.

While looking for the source for the rattles I found a nut on the AC compressor which I think is part number #4.

It looks like part #3 ( the spacer with the ring ) is inserted in the wrong way. In the diagram the ring is between the bolt ( part #1 ) and the bracket , while in the photo the spacer ring is between the HP pump and the bracket body.

Following is a photo of the upper bolt that attaches the pump to the bracket

I referred to a friend of mine that has the same Xantia model and it is assembled the same way as the mechanics did ( i.e. mismatched with the “Citroen service diagram ).

Can anyone tell me the correct assembly of the pump, and what can be the cause to the rattle ?
