Hi, have a 1968 wolesley Hornet (mk3 I think). It’s well down at the front so I’m guessing it needs the suspension pumped up. Could someone tell me where to fit the nozzle if I buy a machine to do it?  Same as a ‘68 mini I assume

It's at the back of the rear subframe, same as other minis.

If the back is still well up you'll probably find the bags at the front have settle (sagged). It's not unusual for hydro to do this, especially given it's age. If it hasn't leaked, then it won't need a simple top up. Hydro bags do have a rubber spring in them, similar to dry suspension, and like dry cars, these will settle too.

 

The upshot of this is that since the front and rears are interconnected, while the front bags have (by the sounds of it) sagged, the rear ones will have stretched. One way to a fix here is to swap the front and rear bags around. Just pumping it up as is you'll likely find the back only will go up, with front not rising much at all.

Ah, that sounds logical. Is swapping them over a hard job, and will I have to pump it back up anyway?  Thanks for the advice

Swapping the bags I wouldn't class as a hard jib but a little fiddley on the fronts and it will take a couple of days if you haven't worked on them before (which does sound the case). You'll want to evacuate the system after swapping around, then refilling, pumping up. Some may say you don't need to evacuate the system, however while this may work in the short term, it will lead to rusting of the system from the inside out. Evacuating the system removes the air from it so rusting can't occur.

 

Given how far you need to dismantle the suspension system for this job, I'd suggest overhauling the suspension at the same time - replacing the bearings, shafts and knuckle joints.

Thanks again - much more work than anticipated but worth it. Any special tools or know how, or just a fair bit of work?

also, can I double check the fault by taking the weight off the front for a couple of days? Thinking if when letting the weight back down it will either sit right for a short while or slump down instantly.

Final question!  If there has been a leak, will there be any evidence or does the fluid just evaporate?

Your help really is appreciated
