And what do these Active Roll Control Rams do ?

Same Speed, Same test, now add to that Anti Lock brakes

This is the rear Active roll control ram in action.

This was filmed on the suspension testing machine which rocks the car to check ball joints and arm /drop-links/roll bar bushes.

You can see the ram working and compensating the roll of the car.

The noise you hear is the testing ramps NOT the cat :)

PASS

                        MOT tomorrow.........washed for luck

Well I have the Active ram all fixed now (more on that later) but, on finishing that I have discovered a nasty leak in one of the leak-off return pipe connectors, namely the one from the Rams to the LHM tank.

 There were two possibilities, either a fractured pipe or a leaking connector.

It was a connecter @No.13. The position of this however is very special. Citroen should receive the "DickHead Design" award for this job, classic !

Part No 13, this is a nylon push fit connector taking 2x 3.mm and 2x 4.mm plastic return pipes, it is wonderfully placed under the boot floor, above the sub-frame.



The gap is 2 inches and is impossible to reach even if you lower the rear suspension sub-frame.
To gain access there is one official method of access, the REMOVAL of the rear suspension and all its hydraulic connections. I did not (surprise surprise) really wish to do this on my ramps, so another method was needed.

The Activa pipe layout........

First lets see just what the situation is......using the scrap Activa I opened a large inspection panel in the boot with a cutting disk.

We see here the Active ram connectors, Electro valve, Activa sphere and the leak back connector




From this I decided on the size of an opening to be made, as there is some access from under only certain access is needed from above, the panel opening can thus be limited to a much smaller size.(center)

 I removed the connector to replace the leaking/split one on the good car. This generates a leak, so to protect the ground I made a new LHM tank.

This catches the leaking LHM and allows the car to remain mobile

A template was made, the top panel cut from the piece removed from the donor car and the area cut to size....talk about a "gulp" moment !

Note: I have used a matching area of metal from the donor car and shaped the hole with round edges..


As with ALL the electrical connectors I come across I use a water seal/corrosion resistor/cleaner wax spray.

Area has been masked for zinc primer and paint.


Note:
The electrical connector is also in a impossible to access position and...NO LEAKS !
