A local farmer to me, when I lived in Norfolk, used to have a car that had under floor jacking rams if he ever needed to jack the car up, does anyone know what car this was, I had a "discussion" with someone today whom insisted there was no such thing, said I was being teased

Hi Greeney,

These Jackall and DWS four pillar jacking systems were used on quite a few makes of cars.
I think they were generally an accessory although I think they were a standard feature of the Wolseley Super Sixes (16hp, 21 hp and 25hp).

The adverts say you can have all four wheels off the ground in 60 seconds.
"Lady drivers are not the only ones who will appreciate what that means, though they will be pleased to hear that only the lightest touch is needed to operate these Jackall permanently fitted hydraulic jacks."

Good for dealing with brake failures too.

Peter

I was looking at a Morris 10 only the other day, and that had the Jackall system fitted

I knew I was right, it must have been the wolseley as it wasn't an aftermarket thing Thank you,
Hydraulics are a marvellous thing, I could drive my DS on 3 wheels without feeling it or loosing any control

Does that apply to loss of a front wheel too?

Peter the DS is MORE stable than a "normal" vehicle with a front tyre gone as the steering and brakes all run off the same system and compensate. I have been in a CX not a DS but the same system, when a front tyre has blown I was in the passenger seat, we were approaching a roundabout, we heard a thump noise and thought we had run over something, went all the way around the roundabout and back up a dual carriageway The only comment the driver made was "it feels like whatever I run over is stuck underneath" it was only after a mile or so we could smell burning rubber, pulled over and found the tyre flat and blown, the amazing thing was even going around the roundabout it wasn't that noticeable.
I drove 10klm from Eymoutiers to my home with a rear tyre flat, it is very steep and winding and I had 2 kids in the back. I didn't notice anything wrong at all. It is an amazing system. Until they go wrong

Hi Greeney,

I was really thinking of an advert or was it a documentary showing a DS happily running with one rear wheel missing. I couldn't find that advert but I did find this:

Yes that clip is often used in publicity items
In the UK in the 70s you may remember an advert for the DS where they blow the front tyre and rear tyre simultaneously as they drive between 2 lorries travelling in the opposite direction. RRoyce used the Citroen system from the 70s right up until the late 90s

Did the MG "Y" type have these jacks also, or am I thinking of something else.

Hi Larry,

I'm not sure about the Y type having Jackall as standard but the pre-war MG saloons SA and WA and the smaller 1½ litre VA all had it as standard.

Logical given the sharing of components with Wolseley under Nuffield.

I think the MG-Y did have them and I think I remember an Austin 16 that I did 'homers' on as an apprentice had them. It impressed the heck out of me. You could jack the front two, rear two or all four There's a couple of items on Ebay just now 250328325269 & 220316113100. One is a set of jacks & the other is a trade document on maintenance.

There were many cars fitted with the Jackall. Lagonda, Alvis, Austin Sheerline, MG, Wolseley to name a few.

I have a service and repair article which I will post in the appropriate place on the forum

Hi
Not a four corners fitted jack system, but I remember having a car on which the jacking points were accessed by lifting the wooden floor and inserting the jack lug into a hole in the chassis just in front of the front seats and you could wind the car up on the jack while sitting in the dry.
It was a pillar jack with a winding handle on the top of it.

[47p2]

The P2 has that system Penman, great if it's raining.

My car should be fitted with a D.W.S. Hydraulic Jack but alas it is not
