ausmini :: View topic - what are these for

ok as i am new to minis i may ask alot of questions like this one.
what are these valves for :?:

Woohoo , I win

Yes , Hydro valves for pressurising and depressurising the suspension . Don't try and pump it up with air , much too high a pressure for it , around 250-300 psi (from memory , anyone know for sure ?) .

Don't you just adjust to prefered finger height..rather than a Number Specifiec by the Leyland :roll:

more of a question...why is one exhaust rusty and the other black with oil...is that a fakey

Don't you just adjust to prefered finger height..rather than a Number Specifiec by the Leyland :roll:

Leyland Black book says with new displacers, pressurise to 350psi early and 400 psi late models, for 1/2 hr. Then let down to pressures shown on chart in General Data for different models

whatever height you want to set it to, i would still do this bit. it is the pressure test at higher than operating pressure to see if you have any leaks. although, i am guessing that this is not explicit in the leyland book, and it does not tell you how much the pressure is allowed to drop in the 1/2 hour to pass the test :roll:

I think you forgot to add the picture Are they under the rear bumper ? If so they are the valves for pressurising the hydrolastic suspension . It has a mix of alcohol and other bits in it under very high pressure and requires a hydro pump to increase the pressure . Do a search on hydro pump and you'll get some designs for pumps .

errrr....Which valves?

which ones? the ones that keep the air in your tyres, and let you put more in, or the ones in the engine that go down and up to let petrol/air in the motor, and let exhaust gases out?

Helpfully, this essential? hydro information was omitted from General Data- in my 1976 book anyhow. Typical Leyland.... It's in the Scientific Publications #64 I think. Will search and find... OK here we go- Early 263psi Late 282 psi No dates or car numbers given for Oz made cars.

I was only using the pressure as an indication of it being very high and way above a compressor (and not air ...) .

NOT for normal pumpup of s/h ones it says.
