Well considering that ACE Actuators seem to have vanished and you can barely find a second hand one, anyone knows if it is possible to service an ACE actuator if it is leaking?
 
of course, an other option is to fit a generic double action hydraulic cylinder, in which case anyone has done it and knows one which fits close enough :)
 
Hmm none on Ebay at present.

On mine rear is new, and I have a spare for front. The ram for front cost more than a whole front ARB.

I would ask the breakers.
 
yeah i have 1 year old at the front but FOR ONCE i didnt think about buying another one to keep in my personal stock so i might have problems when the rear one goes :( i will only consider removing ace if i decide to put an M57 instead of a td5...and even then i will consider putting an electric pump to keep the ace. i love how good it works and how much better mine is on the road when compared to most other (lifted) offroaders
 
I used my Disco 1 300tdi for years until I bought my D2 TD5 with Ace.
I put HD springs on the D1 and gaz shocks. (cos i was going to be doing heavy, long distance fast towing)
Despite the accidental 2" lift, it rolls no more than my D2.
If my Ace starts to play up to that extent I will remove all the ACE equipment and simply fit ordinary anti roll bars plus gaz shocks.
ACE was always a Bandaid way of dealing with roll.:rolleyes:

How did you search for them cos googling out the part number gives several hits, try RQK100000

... there were some experiments i know when people tried to refurbish them and they all failed, it's about 150 bar there not a joke and they have to work both ways not simple to make such piston seals
 
If the other suggestions don't pan out then probably best to go to a breakers if you can live with it being off the road for a few weeks while they inevitably muck you around

Not knowing exactly what state it is in, if it is at all stable you could remove the ACE fuse and drive it. I had to do that once and we live up a very steep and twisty mountain road. (In France). It was OK, like driving a normal car with a normal antiroll bar.
But if yours is leaking to the extent that it is providing no resistance then you'd need to take it a lot easier.
You can drive a car with no ARBs you just have to be careful.

Always the option of stripping it out and throwing some springs on too I guess, but it'll never drive as nicely again

I believe there are kits to replace ACE with ornery ARBs, wouldn't need to change the springs, necessarily, (talking coils here) but gaz shocks made a heck of a difference for me.
 
the Ram is a double acting hydrulic piston if any one has an old one it needs taking apart and measuring as Im sure there will be a stockist that can supply a rebuild kit if you know the sizes, as well as who made them as I cant find amanutactures name for who supplyed them

Seals for double acting pistons are very common. I used to deal with them for compressed air back in the 70s and they would recycle incredibly fast in certain applications.
Maybe a bit less common in hydraulics.
 
The cheap front ARBs sold out a couple of days before I had enough money, I may take the old rear ARB ram to a local hydraulics place to see if overhaulable or an alternate is available.

My concern is more ECUs and solenoids.

I have a dead ECU here. Perhaps I should get a second spare.

That is me! These suddenly got very expensive last year and shortly afterwards became unavailable. Those that have them listed will not be able to fulfil the orders unless they have old stock. We have suggested to customers to take their actuators to a hydraulic specialist to see if they can be repaired, but I haven't heard back from anyone about if they bothered or if they found anyone.

I currently have over 200 people subscribed to stock notifications for RQK100000 !
 
Tom 1979 , do you then not have any old ones hanging around, and can you remember if there are any details on who makes them
