white90 Posted December 16, 2005 Share Posted December 16, 2005 how easy/cheaply can they be modified to give an onboard air system. I think Pauls/Less are great but a bit beyond me, whereas an aircon one may be far cheaper/easier prospect. Quote Link to comment Share on other sites More sharing options...

If you do it Tony I have a spare air compressor from a 3.5 V8 EFI Aircon in my spares bin... £10. Quote Link to comment Share on other sites More sharing options...
white90 Posted December 16, 2005 Author Share Posted December 16, 2005 I'll have it please can I collect when we come to Slindon in FEB? I'll Paypal you the ££ or post cash all I need now is the tensioners etc from a Discovery. I'll ask Will if he had Aircon on his one that rolled. cheers Simon.

SteveG Posted December 16, 2005 Share Posted December 16, 2005 Why not go for an air suspension system out of a Range Rover. You get a compressor, tank, pressure release valve etc and 150psi, ok for doing tyres. Cheers Steve Quote Link to comment Share on other sites More sharing options...

BlackTJ Posted December 16, 2005 Share Posted December 16, 2005 They are becoming very common in the Land of the Free. Over there most people use York compressors as they were fitted to Volvo's. I have seen one guy in the UK use a compressor off a Peugeot 405. Check out this site http://www.kilbyenterprises.com/ for FAQs etc Main issue is the lubrication. Normally the aircon gas lubricates the pump so you need to add oil. Best solution is to "catch" the oil and recirculate. If you live anywhere near Ivor Daniels then I would go and visit him. Mike Cuff's Jeep seems to have taken up residence and that has a full OBA fitted by Mike including air tank alternatively drop Mike an e-mail or Phil Walker or Sam Fletcher. They have all fitted them. Sam Fletcher sourced most his fittings etc in the UK. Quote Link to comment Share on other sites More sharing options...

Ex Member Posted December 16, 2005 Share Posted December 16, 2005 (edited) I used a York from the junkyard. At least around here they are plentiful in many vehicles. $20 or so and it is in perfect condition. You don't need anything special. For the first year, I just hooked a hose directly up to it. I've since added a tank and a pressure switch, but they are not needed for filling tires. If you don't have room for a York, then any old AC compressor will do. Just add an oiler on the inlet or squirt some oil in before use. Edited December 16, 2005 by Red90 Quote Link to comment Share on other sites More sharing options...
white90 Posted December 16, 2005 Author Share Posted December 16, 2005 John that looks like the setup I want simple no tank just for airing up tyres/air tools the oiling side of thimgs? Do you add oil before every use? do you need a seperator? Quote Link to comment Share on other sites More sharing options...

Tony, Mine is a Air Con one ! off a Discovery Its best to take the oil out before you use in it your tyres as it "don't" do them any good, to use air tools you will need a reservoir, but just for tyres you can use it straight off the compressor I'll give you a ring tommorow and we can discuss it amongst other things !

Guest diesel_jim Posted December 17, 2005 Share Posted December 17, 2005 I've got one of those square york's in the garage waiting for me to glue it to my 300. excellent bit of kit.... 180psi @ 10cfm... thats more than my mains compressors got!!!

simonr Posted December 17, 2005 Share Posted December 17, 2005 A nice simple option if you just want air for inflating tyres: The output line on most LR compressors has a bore just the right size to be tapped as 1/4" BSP - the same size as most air fittings. If you were to buy a compressor, a 1/4BSP tap and a female PCL connector and put a switch on a remote lead to engage/disengage the mag clutch it's about all you need. The remote lead means you just manually switch on the compressor when you are using air. No need for a pressure switch then. As Les says, empty the oil out and fill the interior with high temperature grease. Barely any ends up in the air - not enough to worry about anyway. Mine, running without a reservoir will run my rattle gun quite happily with the engine doing about 2200rpm Dead easy. Si Quote Link to comment Share on other sites More sharing options...
MarkieB Posted December 17, 2005 Share Posted December 17, 2005 As I understand it, the reasons for the popularity of York compressors for OBA include: the piston arrangement — it's different to most compressors, puts less oil into the circuit [mount it vertically] the ability to block the one oilway that spews oil into the circuit at all — although it's a bit technical, it involves tapping the little hole then putting a suitable screw in it. A web search should produce instructions. Quote Link to comment Share on other sites More sharing options...
simonr Posted December 17, 2005 Share Posted December 17, 2005 The main down-side of the York compressors is the sheer size of them! Particularly in a defender, it's hard to find anywhere to put the thing. The performance is no different to a regular can type swash-plate compressor. If you fill the latter with grease, the amount of grease / oul in the air out is tiny. I'm using one of these to run air-suspension and it is running all the time on or off the road. Filled with grease, I have had one unit fail - although it was due to the inlet non return valve leaking which is more likely due to ingress of dirt. That was after almost two years operation. If you were just using it for tyre inflation & air tools - so long as the compressor is not pre-broken, it should out last the rest of the vehicle!

Turbocharger Posted December 17, 2005 Share Posted December 17, 2005 Any clues for fitment options on a 300Tdi if I've got a winch pump where the aircon pump would sit? Or should I just go electric with a big reservoir? Quote Link to comment Share on other sites More sharing options...
Paul Posted December 18, 2005 Share Posted December 18, 2005 Tony,Mine is a Air Con one ! So is mone, from a mid-80s Mitsubishi. Main issue is the lubrication. Normally the aircon gas lubricates the pump so you need to add oil. That's note quite correct. The refrigerant is not a lubricant. In A/C systems the lubricant is an oil that is added into the closed system and circulates around with the refrigerant. When you open the system, the oil is eventually lost through the outlet, and must be replaced in some other way. The output line on most LR compressors has a bore just the right size to be tapped as 1/4" BSP - the same size as most air fittings. Exactly what I did. Take the head off, cut off the old flare threads and tap it out to bsp. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted December 18, 2005 Share Posted December 18, 2005 For the York, you don't need to add oil. If they are in good shape, they don't pump it out either. Ine has lost zero oil in 18 months. They DO put out a lot more than the Sanden style as long as you get a long stroke version. Quote Link to comment Share on other sites More sharing options...
