engine driven compressor

**O.B.** · 2009/09/25, 03:05 PM

I have no aircon, so the mounting of where the comressor would have been is empty. The fanbelt is not there, but the crank pulley has the extra groove for the aircon belt. I'm sure I will be able to source a tentioner for this belt from a scrap yard.

My idea is to mount an engine driven compressor on this space. Fitted to the compressor is an electro magnetic clutch pulley that can take the belt the aircon compressor normally does. That pulley should also be available from a scrapped unit.

My question is where to source a suitable pump, an air tank, and a pressure switch that can switch the clutch pulley on and off?

Cost is a factor. How available are they form a lorry grave yard? Would old lorry air brake compressor work, or are they too big?

Hi OB,

Try Numatics SA for the switch & 011 8654453 in Wadeville.

Mabe an aircon/fridge unit would be smaller than off a truck?

Not sure about tanks but check in yellow pages for compressor repair guys, they could help with all 3.

Hope this helps but not been this route before myself.

I presume you are looking for something like in the picture. It uses a normal aircon pump with a standard compressor pressure switch that can be bought from builders warehouse.

That is exactly what I had in mind, except for the pump. I dont have the aircon, so was thinking towards a piston type compressor. This would use te same setup, minus the oil filters/seperators to clear the air of oil

That is lots of background thanks 4ePaj

I have a Terrano aircon pump from an import motor.

Offer me some money......

4e You have all the info, You know Pajero better than mitsu, you have seen Pikanini''s pajero, One question........Where do you mount the extra compressor?

... I also have a brand new AC compressor.

Where to mount? Dunno! That is why the compressor is still in the box!

**hbannink** · 2009/10/08, 07:38 PM

Seriously thinking of mounting close to rear wheel and doing a McGyver trick to run it

I saw a refrigerated trailer in Henty's Bay (many moons ago).
It had a AC pump fitted under the chassis, with a motor-cycle chain drive off the hub to drive the pump.
Everything in the trailer was frozen solid!

You can buy a tank from these guys. It's aboutR380 for the 10l tank.

Time to get the project going. Spending lots of time reading up.

I have found an old Sanden SD7 compressor, was on a Ford. Got it from a scrapyard, for R500. This is the one to have according to US forums where they do minitrucking. That is those funny looking pickups that can inflate and deflate their airbags so that the fenders are level with the pavement .

Opening it, all the valves was shot. I opened it because I wanted to do an oil modification for it to work with grease, and not with oil from the air pipe. Glad I did otherwise I would have realised it was useless by the time it is on the motor.

Anybody know of a scrap yard where I can find a York type AC compressor? These have a sump-like lube system. They were fitted to 1970 Jaguars and older Fords?

Neem baie fotos!

**O.B.** · 2010/11/30, 08:30 AM

Ek sal so maak

**O.B.** · 2010/12/01, 02:08 PM

I was looking for the York, found two, but there is not enough space between the mounting and the bonnet

So back to Sanden aircon pumps.

Visited Iceman automotive aircon specialists in La Montagne (Really friendly, can recomend them!!!) The Sanden SD7 is not the right type. One needs a Sanden 5cylinder, the difference between the two is that the 7cyl has a wobbly plate, and the 5cyl a swich swych

plate. If someone else want to go this route get one that has not got a wobbly plate.

I reviseted the scrap yard wheere I got it and tried exchanging it, even if it would cost R100-200. They refused, which is their full right. But I must mention those are two unhelpful idiots, not even willing to give friendly service. It saved them R500, but I would never use them again. It is called Second Hand Auto Spares in Stormvoel across Apollo21 truck spares. Stay away.

I was sucessful with the tank. Got it from Apollo21 truck spares in Stormvoel, I estimate at least 30l tank including mounting brackets and a drain valve fro R375. Friendy service I can recommend them.

A good photo report will follow. Tank and coupling in, pressure gauge on the console, need a

1way valve, ordered on Ebay bit I think it got lost in mail.
Bulkhead fitting to take the pipe trough the firewall to the console for the pressure gauge
aircon fan belt tensioner. R1400 new, that is a price of a good compressor, defy the wwhole point....

Still busy. Now the last bits and pieces need to be sourced. Finding the tentioner for the aircon belt is scarce secondhand. I have most of everything it is just the last few bits and pieces.

Anybody have a spare aircon belt tensioner for a 300 TdI?
also, any contact for pneumatic fittings?

OK jelo no need to shout

Some progress pics so long
First pic is the gauge fitted still fitting the carling switch that will activate the system
Second pic is the quick coupling I fitted next to the fuel filler cap
Third pic is a pic of the tank under the body. Not a good image, I will image the brackets etc on completion.

Lots of other pics still on my old phone, will post a proper report later
