As I was doing research on getting a replacement ac compressor for my D1 300tdi, I learned a lot about Nippondenso ac compressors. In a nutshell, the 10PA17C it uses is very common. There are basic differences such as a few different mounting point options, manifolds, and different pulleys. However they are alll very similar. Here is the one I found closest to the original: DENSO Auto Parts A/C Compressor 471-1349. It has the correct mounting points and manifold. The pulley is a 4 groove but I cant say for certain it is back far enough.

It is listed for a 94-96 Jaguar XJ12 6.0L-V12. However, I found a new one for a mid 90s BMW 3 series on eBay, Denso number 471-1114 for $90 shipped. I had to use the manifold and pulley from my old compressor but everything else was a match, even the clutch parts (except the pulley). Well, I did splice the connector plug. I also pressed out the new bearing from the BMW pulley and installed it in the old pulley. It was an extremely easy job even with the extra swapping around.

I would have had the whole job done last Saturday afternoon if I had not forgotten I left the new belt at our other place (too far to go retrieve) and if I had known the Freon cans as of May last year have a smaller threaded port than my old piercing valve fits. Why would they change that? It would have been done last weekend if any parts store in town had the belt.

The V8 compressors are also Nippondenso 10PA17C but the manifold, clutch pulley, and front mounting points are different. However, the same basic compressor can be found on other vehicles. Although, as easy as that one is to find specified for a D1, I doubt it is worth the trouble looking around. However, if the only problem is a seal leak, they are very easy to disassemble and replace all the seals. You can get a seal kit for less than $20. A new pulley bearing can be had for $15.

Very nice that 300tdi... To have maximum qualification, only fan cowl is missing!

Regards
Thank you. I am trying to decide on either an electric fan or finding a fan cowl. At this time I prefer to install a fan cowl but they are NLA new.

I used a Defender fan cowl which is a little shorter but just long enough to do it’s job of allowing the fan to pull the air through the radiator but not its job of protecting fingers. The Defender cowl still can be purchased new. The D1 is NLA new and I had no luck finding a used one.

If you need a 300TDI fan cowl I can recommend some places in South Africa where I buy parts when I'm there. Shipping might cost more than the part but hopefully it doesn't go through the Suez Canal.

Thank you, I did buy and fan cowl. The Defender 300tdi cowl fit well enough. I’d still be interested in the resource.

Here's where I usually start:


I can't link to it here, but there's a guy in the KwaZulu-Natal Land Rover Owners Club who parts out trucks in Richards Bay and posts his listings on the club Facebook page. It's a private group, but if you want his contact info I could probably find it.
