Is there anyone on here near Bolton with a proper hydro pump. I am thinking about evacuating the entire system and refilling.

What are you planning? If you intend to refill with hydro fluid, you might have a problem as I doubt hydraulic fluid (oil) and hydrolastic fluid (water and alcohol) will be particularly compatible. Vaccing out the system will put the hydraulic fluid into the dalek.....

The hydrolic oil was only ever used in the first place because there was a twenty gallon drum of it handy.

If the system is filled with hydraulic oil I'd emty the system with just a hose and connector fitted to the connectors first, in order not to get it into the pump.
Then filling the system with hydrolastic fluid or antifreeze coolant, only to empty it again right away. In that way you'll perhaps be able to "flush" the system for oil. At this stage, perhaps it's an idea to fill the system with hydrolastic again, drive it for a while and then empty the system and evacuate it using a proper pump. I don't think small amounts of oil will do the pump any harm, but can't confirm this in any way.

Ok, I suppose you have the car on a high ramp/ hoist then, with its weight on the wheels, allowing you to stand clear and safe when it collapses? I imagine splitting the joints at the displacers will make the car go to the ground instantly, and not to mention make a hell of a mess, spraying the fluid all over.
I wouldn't think of emptying the system in other ways than by the schraeder valve connectors in the engine bay. Also, in order to empty the system as much as possible, the car should have its weight on the wheels.
By all means, I stand to be corrected if there are other ways to do this.
Regards, Tommy

That's a fair shout. I hadn't thought that it would not empty on stands. Valve and tube it will be then.

Interesting. I've just removed the hydro pipes on the red one in order to scrub its bottom. Despite having been disconnected for months, plenty of fluid was still lying in the pipes and no doubt in the front displacers as well. The rears were removed altogether and drained.
I suspect that Tommy is right. Crack the rear joints with the car raised at the back and then let it down gently might work.
Chris.
