Hi All!

A while ago I have bought a 2.5N/A 110 HT Defender (I know it is actually just named as a 110) in France. A very nice car with low milage, has always done her job on the wine yards. I am restoring her at this moment, getting the chassis galvanized, respraying, converting it into a soft top, and overhauling the engine, transferbox and gearbox etc.
While I am taking it apart I noticed there is no power steering because of the manual steering box.
I have a hydraulic power steering set to put on on the steering rod and also a hydraulic pump on the engine. Also the hydraulic pump is driven by the same singel belt which also drives the alternator and the fan.

It is a Power steering set for series and early Defenders, so question SOLVED

That pump doesn't look like the power steering pump on mine, and it isn't mounted in that position either. And mine doesnt have the big ram on the steering linkage either. Just a steering damper. like a horizontal shock absorber.
Where do the pipes from the pump go?
If they go to the steering ram thing, I would guess it is a home built steering assist. If they go elsewhere. like a hydraulic winch, it will be for that.

It is quite easy to upgrade to a standard power steering setup using the pump, box, and a few other bits from a later model 110.

The manual steeringbox is original isn't it?
One pipe of the pump goes to the resevoir the other goes to the hydraulic ram. On the ram there is also a second pipe which goes to the resevoir aswell.

OK, so it is a form of power assistance.
It maybe something that landrover made, but it isn't one that I have seen on landrovers. Maybe someone will recognise it.
If not, it must be something a previous owner has made up.
You can either keep it, should be easy enough to get the ram serviced, or you can take it off and go back to manual steering, or you can retrofit standard power steering from a later model.
 
Looking again at the existing set-up, it does look very strong and functional. Possibly made from old tractor steering parts.

If it drives well, and you get the amount of power assistance that you want, I think I would be tempted to keep that system.

This is my take on this as well...

We have an old ferguson with a similar system - the valve on the ram is the weakest part of the system, but they are a serviceable item.

Here's a similar system on the bay of e:-

I would think it will be fine ongoing, provided the ball joints and bits for the ram are available! :)

Agreed - thus the availability of parts might be a good decider on whether it stays fitted or not - suspect the ball joints as being the least available...maybe?

Is there a make / manufacturers plate on this set up at all ?

Availability would be my make or break on whether to keep it too! :)

I can usually get balljoints for old stuff, places like agriline keep an excellent selection.

And you are quite right, identifying the source of the aftermarket bits would be very helpful.
OP needs to look for plates, stamped numbers, etc.
 
Here's another pic showing the same concept fitted to a DB990 - ( I remembered a neighbour having one - no DB's here :D)

you'll probably find calzoni made pumps of various displacements - and the one fitted is the right size for the application - your favourite search engine will tell you more.

The ram will probably have a manufacturers name on it too - under the years of crud / rust. Any hydraulic firm should be able to supply seals, and fit them if necessary.

A lack of power assisted steering will largely be a personal thing - effort is much higher, especially at low speeds, and if you are going for wider tyres, you will probably regret not having PAS.

IMHO, If you can get service items for the system, keep it, otherwise, fit the "normal" "LR" type PAS box, pump etc.

I was thinking about old tractor parts too, Looks alike indeed! But the pump, is that also just a random pump then, and is it possible it is fitted onto the bracket which is used to lift the engine out, it that located on the same place.
Also the belt is also longer ofcourse.

On the pump is the name 'Calzoni' stamped (see Pic.) the ram should be serviced at a argi related business I think?

How does a 2.5N/A dives withour Power steering, is this very bad or ... I do not have a refrence.

Just a hydraulic pump of an ag machine, at a guess. I think Calzoni are still around, they might help.

Any hydraulic hose place, or a tractor workshop, should be able to sort out the ram.

Never driven a 110 with no power steering, but I drove a 109 for years, fine at speed, but heavy on the arms for parking and reversing trailers. 110 is a bigger heavier vehicle, power steering would probably be a more pleasant drive.
If you are planning bigger than standard tyres, definitely get PS.
