Shouldnt really be a problem as 200 and 300 same power and torque, its not like either box is tough as odl boots!

You may be better off with a four bolt PAS-box, I will take a photo of mine later for comparison. I'm sure that is your problem.
The fan on mine just brushed the PAS box on the corner of the blades which soon wore away.

Don't know how much smaller they are to the 6 bolt, but worth thinking about.

I would be more concerned with how close the PAS boxwas to the TDi's timing chest rather than the fan, You can always use an electric fan, but if the engine moves forwards when off roading the timing cover may get too close to the PAS box.

Looks like the 4 bolt Is different way round and smaller too then my 6 so might just do the job. More pics of mine, you can see how far the fan hits it.

The area that your fan is hitting isn't there on the 4 bolt box. If you look closely at the fan blades in my pics you can see the tiny amount that has worn off the corner of the blades.
My PAS box is from a 300tdi Discovery, fitted with a Defender drop arm.

Power steering pumps are expensive. I'd do what was suggested above and start checking if the bulkhead and gearbox tunnel you have will fit the chassis/engine set up. Any problems here will be more hassle than the viscous fan. As has been said you can just leave it off and fit an electric fan, which will be a lot cheaper than a new PS box.

The four-bolt PAS boxes are fitted to 300tdi Discovery's, there are plenty around due to the raging rot. You may need the four-bolt hose connectors to mate with a 300tdi PAS pump.
If the gearbox is the standard LT77 in the standard position there will be no problems fitting the original bulkhead, seat-box and trans tunnel.

I would still be checking it all out.

RRs 4 bolt above does look like it might fit, but think you are right, better check to see if other things are gonna fit too.
The PO also said he had a brand new Kenlowe fan to fit , but that wasn't in the boxes of bits I got when it came, he did say that bulkhead and other bits Would fit OK, but better to be safe then sorry.
Will have to get someone who knows exactly where things should go when I trial fit them as I aint got a clue as I did not take it apart.

If everything else fits OK Im sure I should be able to find a second hand disco 4 bolt, Was yours already fitted to your defender ?

Aye, worth checking. Presumably, he thought the PAS box was going to be ok. Although, if he had a kenlowe fan ready to go in!

I bought the world's most rotten Discovery and used the engine, transfer box and steering box.
The pictures make it look better than it was.
Yes they would if a disco box is fitted because the box is longer. hence engine further forward
If not you will have to bolt gearbox in place and sort engine mounts, I used a plate of steel about six inches long and drilled two holes in it, one for the engine mount and he other about four inches away to fit the chassis mount,

They don't sit that far forward! Everything behind it would end up in the totally wrong place too if it was that far forward and if your engine jumped that gap then that would be the least of your worries!

Agreed, it's only about 4 inches further forward than when using a defender gearbox

The 4 inches of exhaust pipe sitting on my workbench can attest to that!

On the point of the fan, I never ran the viscous on my 300tdi Disco and it was used as a daily driver for getting to work in rush hour traffic and I have never had a Viscous fan fitted to my Defender (I don't even have electric fans anymore as I took those off for a rad swap and never got round to refitting).
Point being, you don't need the fan in most situations. Low box slow long hard climbs on hot days maybe, but even then if it is just for fun you can stop that behaviour and let it cool a little or just drive it steadily at higher speed and let the air through the grille cool it all.

Depending on how you intend to use your Defender I would also consider ditching the viscous as others have said. I took the fan off my 200tdi 90 fitted an electric fan. The electric fan never came on as the engine never got hot enough so I removed that too and ran it without for the 3 years I owned it. The engine runs much quieter / sweeter without the drag of the viscous. If you do regular towing or slow off-road climbs I would fit an electric fan just in case but wouldn't hesitate to run without any fan for normal driving.
