I think he made more work of that than necessary Marc, I've never had to move the bumper or headlamp and in the first few frames draining the tank can be done by disconnecting the hose at the bottom join into a bowl instead of having to keep using empty LDS pots and having an elbow full.

I also repaired the suspension pump on my C5. Some of the pics might be useful.

I found your blog. Can you tell me where you got the replacement brushes from (that you said you did)? Thanks.

Raise the vehicle on a max. position, jacking, removing the right wheel and the front of the fender. Leaning car pivot holder and placed in the lowest position REQUIRED!!!. Deprsharize using LEXIA or other means to loosen the air vent on the right WING INNER FRAME.In the end, disconnect the battery.
To remove the tank, top detaches Reversed top, underneath the fender from the tire return hose and drain into a clean container / tube oil
Image
Lift tank and it is another disconnected Reversed and suction hose
Image
Once removed tank, detachable Reversed pump and the coupling of the electronic block
Image
Continuing with disconnecting the suction hose from the pump to the suspension and from the pump to the rudder servo
Image
Image
Following two tubes of high pressure to the front and rear axles. Particular attention to the two green "O" ring - one fell, but found it. Without them there is no seal then.
Image
After unscrewing the nuts on the rear pads and disconnecting the motor cables take out dead pump. Unscrewed from the pump to the hydraulic unit is removed the back cover, remove the wiper shaft is furnished and management, pull gently pump, store counter of the box and develop rotor box - with a reverse thread.
Image
Image
It totally disassembling and cleaning. At the front end of the pump shaft has a nut underneath circlip - is removed. Camp hood is kapselovan but munched - change for pennies. Back is a bronze bushing - after washing lubricated.
Image
Image
Image
Image
And that is the culprit for problems.
Image
Image
Image
Because things smack ...
Image
we decided to see what was in the control unit of the engine, but the bastards have it covered with black paint, though in good will could get our hands on the marking of transistors
Image
After a wash, it is as ever wash all offal motor
Image
We changed the front bearing, rotor went fine grinding and balancing
Image
Image
Image
Assemble in reverse pump smeared with black silicone management (factory was also smeared) and assemble the car
Image
Image
Image
Image
Pour oil and now attention - to be swell tank with over 0.5 atm. pressure to be able to lift the pump. Quite straining fell :) dry after repair pump is not heard, and quite disturbing. Is less citroaerobik (up and down) and move the car in the shade cleaning mistakes and train his brain

In the end a video
