castor oil from the first pressing (not pressure 1).. The same principle as with olive oil.

I can't even remember whats in mine.....i'm guessing a light engine oil but castor oil must be available somewhere..

"Pressure one" must be a lost in translation from Italian to English maintenance manual!!

That now makes sense as there is a lot of first pressing castor oil on ebay etc....

Warning dont mix with anything else as it gums up.. And dont drink it as it is a strong laxitive

Just off to the chemist!

I am sure I was told the correct fluid to use is a Glycol based anti-freeze diluted with 50% water.
One thing to memember is that it is difficult to get air out of the system, particularily the regulartor bag/control knob. When you have filled the rest of the system, take the regulator bag/control knob out of the car, fill with fluid, then reinstall, trying not to spill anti-freeze all over the interior!  The regulator and shocker bags are available new from various vintage suppliers...... probably worth replacing them anyway.

A bit more clarification. The fluid you use depends on the shockers you have. From what I gather, originally 1st series were just friction, but there seems to be quite a few fitted with Andre Hydro-Telecontrol H.C/2s, they use a mixture of 30% glycerine and distilled water. Later 1st series, from construction no. 6601 on, have SIATA units that, according to the LMC "Maintaining An Aprilia" booklet, use brake fluid. 2nd series have the SIATAs up to no. 11380 and then Houdaille units from then on. I think that is correct!
I have the Andre's and use the glycerine mixture that works fine, once you get all the 17 connections and various other bits to not leak and hold pressure. I'm sure the other setups would have similar problems!

I also have a set of Andre's but not fitted as the bag in the pressuriser has perished.  New bladders for the shockers are available but not (last time I looked) for the pressuriser.  Anybody know where I could find one?

Just to confirm the Houdaille's are adjustable but not from the dash Angry. A bit like the spax system. Same type of thing on front sliding pillars too on later S2's. So fully independant and adjustable in 1946.... Grin

Thanks Ade.

As can be seen on page 5 it is particularly vague on what the replenishing fluid is. But as Lancia Aprilia S2 manual states Castor Oil No. 1 Pressure, I have bought some pharma quality castor oil on ebay.... The manual also says this oil can be used for the back axle but I will stick to EP140.

The Houdaille shock absorber fitted to the 2nd series is not the same as a Telecontrol.  This link relates to the Houdaille type

I notice they suggest glycerin!
I would guess that brake fluid would be the stuff for Telecontrols.  I have got my new bladders.  Watch this space!
