1985 Landrover county 110 aircon

[Deanslost]

Hello Boys'n'Girls,
I was hoping someone can tell me the brand and model of the correct air conditioning compressor for the above car. There will be four digits after the model number for example Brand: Sanden, Model: SD15####

Mine is missing the compressor and the condenser coil and drier.
Maybe someone will have the correct part numbers and a link to where I might buy them.

I am a fridgie I can fix it myself and have a supplier to source this stuff but they don't have records for my car.

I have found in the past if I want to buy something for my landrover (And even the nissan before this) it will cost$$$$$ but if I can cross reference the part and order it for say a holden you can save quite a few $

Any help appreciated
Thanks
Dean

sorry the significance of the four digits after the model number it they indicate the format i.e. pulley size, belt type, clutch voltage, e.t.c.

AFAIK they are no longer available new.

You could try one of the LR dismantlers (like Triumph Rover etc)

Compressor: Sanden SD7H15
Condensor: Sanden MFC-1068AE

Thanks Judo,
This is exactly what I was looking for.

87county, they might not be available genuine but there is usually something compatible. If you have the original manufacturers model number I.e. not Landrover, Sanden. Then there is usually something compatible around if you know who to talk to. I've got an old Nissan up the back that has a compressor and condenser in it I'm hopeing that they will fit without too big of a hammer. If not I now have the numbers to cross reference.
Thanks Dean

original was a 5 cyl sanden. SD508-SD510 you can buy these chinese
but a SD7H15 [7 cyl] is the new update compatable.


I have fitted Zexell [diesel kiki] or tama as they are often cheeper and come as commercial pump with a good range of pulleys.


the original equipment used 2 silly 3/8-7/16 width belts that will sit in the bottom of the sanden double A pulley.and the Isuzu had double 11 mm puley.


had no problems fitting 1 [13A###] 13mm wide belt or 2 1/2 belts and a tensioner to suit-even used a flat back idler type.


the ports on a 4BD1 diesel are not well placed normally using a rotor lock fittings with back off taps.I relocate the low port to next to the evaporator and use the dryer.


I say diesel because V8 of that time had GM Harrison pump. lots of people changed over to sanden pumps after the first compressor destructed.

The aircon in an '85 County could never be made to cope well enough once ambient temps hit mid 30's - sorry to say. I had new condenser unit re gassed & ended up putting a plexiglass partition behind the rear seat to help & still ordinary.

My dualcab still runs the original a/c system and it does work quite ok in the smaller cabin area. I wouldn't say it's excellent but it makes it quite comfortable even when outside temps are in the high 30's/low 40's. Years ago when it was running on R12 it would get that cold that you would have to drop the fan speed to low, now on 134 the fan is on high all the time. Wish I still had some R12 lying around:(

Back on topic, I still have an original Sanden compressor of an Isuzu down in the shed, if you want I can dig it out and get the numbers off it.

[Deanslost]

I haven't had much chance to play with R12 but from what Ive seen and heard it was a great refrigerant. My 1949 kelvinator beer fridge still runs on it and it seems to work well:D

134a runs slightly higher high side temperatures then R12 and to work any where near as efficiently requires a larger or more efficient condenser.

I will have to see what I can come up with.

I have just fitted a new Sanden Compressor (same model as referenced previously) to my 87 County AC System.

It was also regassed with Hychill HR12.
HyChill Refrigerants - Manufacturers of Hydrocarbon Refrigeration Gases, HC's, HR12, ER12 - CFCs, HFCs, HCFCs, hydroflurocarbons, R12, R22/502, R290, R600a, and R134a Replacements (http://www.hychill.com.au/products/)

Seems to work very well normally, although does struggle a bit with ambient temps above 30.

There has been a few comments on HyChill recently. A few questions, since you're a fridgey!

Is there any reason I couldn't use HyChill in my County system? I.E. same drier, etc as used with R134a now?
Why did you choose HyChill over R134a?

Cheers.

I didn't choose Hychill,

As far as I know there is no reason you can't use Hychill.
Hychill and Ozchill refrigerants are hydrocarbons blends, usually blends of Propane and Butane.
Hydrocarbons are flammable/explosive to varying degrees when mixed with oxygen.

Don't get me wrong these refrigerants offer great improvements in efficiency and they are relatively cheap and from what I have heard the amounts of refrigerant required in a car shouldn't be enough to cause a problem.
The problem with hydrocarbon refrigerants is there are no set rules. As a refrigeration mechanic no one can tell me what standards I have to meet, what safety requirements have to be conformed to.
There are recommendations that if you search for them and are lucky you may find them and then there is hearsay. The hearsay is usually generated by the refrigerant manufacturers from either side of the argument.

The Company I work for has decided not to use these refrigerants until the rules have been set in concrete. We recognize the benefits but we recognize the risks especially when some of the equipment we work on requires 16 kg of refrigerant or more, can anyone say big buddaboom.

Sorry just to clarify Hychill HR12 is not R12.

R12 is a refrigerant that has been around for more then 50 years and although being extremely efficient and flexible was deemed to be too hard on the environment.
Hychill HR12 is a Hydrocarbon blend that has been designed to mimic R12 as closely as possible.
