Repairing a Hydractive Electrovalve...

[CitroJim]

Yep, that's exactly it Richard...

Interesting thought to give a Xantia a set of sacrificial anodes

[Old-Guy]

Hi Jim, some of the inhibitors available in the marine industry will offer a solution to this corrosion problem. I#ll dog out some of the data sheets for them and post up.

Ideal for rear brake callipers too!

[Xantidote]

something like magnesium (which AFAIK is what they bolt to the bottom of ships

I'd assumed the sacrificial anodes on ships are of zinc - certainly this is what's used on "small craft". Even zinc anodes are not cheap

[handyman]

Hmm, would not use magnesium as a sacrificial anode, it even corrodes in air when not protected, not as bad as potassium though.

Zinc would be the way, but if there were sacrifices to be made I'm up for using virgins! Only kidding, honest.

Probably, dunno where I got Mag from.... zinc is the sacrifical annode in galvanising of course...

Telling thing though is the most important object in the last photo. Was it still warm?

it certainly looks like Sir Jim used at least two whilst repairing that valve, as theres a different cup in the first photo, or may be the first cup contains oil to cool/quench the hot metal and not the thirst of Mr Eastment

[CitroJim]

Only one bag of defcaff I have to confess Malcolm...

No, the reason for the two cups is the first photo that explains the problem was taken much earlier. Potentially a year or so previously...I still have the mug and it's still in very regular use...

obviously you were not feeling your self then then Jim

you only had one over a year, shirlley not i really find that hard to swallow

[Old-Guy]

Dare I ask how the repair has stood the test of time?

Wish I had a workshop where a proper lathe could be installed

BTW I saved the front electro-valve off the VSX if anyone wants it; not sure if it actually works. The VSX was strictly a temporary run-about until I could find the time to repair the Green Lady. I only did the bare minimum to the VSX to make it safe and keep it reliable, so I never did thoroughly sort out the suspension.

I've not yet had an opportunity to try it so I can't yet answer your question Guy...

If the body of an electrovalve is OK then it's worth saving as the guts from a corroded one can always be swapped across...

We can pop it on my HDi if you like....

We can indeed Chris

[raynoon]

So.... did it work?

[CitroJim]

Don't know yet Ray, still awaiting one of mine to fail in order to test it.

No reason at all why it shouldn't work

[Rhothgar]

I'll be looking out for this tomorrow Jim.

I guess it comes off the regulator.

Perhaps this also explains why my car feels really bouncy but solid with it like it's on max suspension but it's not?
