Probably more difficult on something already with aircon (if you want to preserve it) but not considered using an air-con pump? Got one on my 300 for running the diffs, air horns and also have an outlet for it for any tools / tyres. There's a P38 tank tucked up behind the rear wheel - almost as if it was made for it. I've comfortably run my 50A plasma cutter off it (and that eats air - a 200l 3HP twin cylinder compressor struggles to keep up with it). The engine was just idling and the pump kept kicking in and out because it can generate such a volume of air at high pressure (mind you it does effectively have 100hp behind it!).

How do you get by with lubrication if using an a/c compressor for air? I though that there was generally a lubricant in the a/c gas, and that running degassed did bad things to the pump. I could well be wrong!

I ran a little oil drip feeder and then an oil separator initially but the separator kept blowing up under the pressure. I can't remember off the top of my head but that compressor will comfortably chuck out in the region of 15-20cfm at 200psi. Unlike most "shop" compressors that quote free-flow air.
Admittedly it was a cheap £3 eBay special but at the time my search skills were failing me and only finding cheap eBay specials or £100 workshop ones. I wasn't going to spend £100 on the filter when the entire system cost me £50. The last 2 years I've been running it without lubrication (admittedly haven't run the plasma off it since) and it's been absolutely fine. With the P38 tank it doesn't kick in very often and if the engine has a few revs it's well under a minute to fill it up to full pressure. Occasionally when I remember I squirt some WD40 in there (probably about 12 months ago...) Ed 82 Hotspur Sandringham 6x6 95 Defender 110 300Tdi |

Very interesting thanks. Is it a standard Defender a/c compressor?

I did consider that. Vehicle has air con though. I have a 300 tdi ac pump around for that purpose somewhere. Cheers

Yup, Denso unit. Worth bearing in mind most of my stuff is running at 140psi. There's a standard 240V switch off a compressor that switches the pump on and off with blow-off valve attached. There's a separate regulator (nicked off the same compressor) to regulate down to 90psi for the diffs. Funnily enough was asked to take photos this morning by someone on LR4x4. All standard 300Tdi parts until you start plumbing in the air-line.  Click image to enlarge Should also mention the 5 or 6mm pipe (whatever the standard is for the Ashlockers) is what was feeding the plasma. There's 10mm ID pipe off the compressor but the moment it hits the regulator it goes down to the smaller one. Basically I couldn't be bothered to re-tap the P38 tank so left most of it as the smaller stuff. So it shows just how powerful that compressor is if it can run a hungry plasma cutter through that diddly little pipe. Ed 82 Hotspur Sandringham 6x6 95 Defender 110 300Tdi |

Arbs 5mm. Ashlocker 6mm
Ashlocker will work slightly higher pressures than arb, run mine at 100 to 110psi. Arbs are 75/90 psi normally. On other news, new drop arm fitted this morning, track rod end style complete with sumo drag link and hd greasable track rod ends. Also had these new polybush covers for the track rod ends from Gwyn, quality seems good, will see how they last.

I assume the pickup is for installation in the tank?
I can't claim credit for this idea (that goes to John / FridgeFreezer on LR4x4) but he had a neat solution. A swirl pot installed in the return line to the tank. Can't remember what size it was (only a litre or two if I remember correctly) but sufficient to run the heater at full blast for 24h. The return fed in at the top and the return to the tank was tapped off from the top but the heater tapped into the bottom. The elegance came in that you didn't have seperate tanks, you didn't have to faff with the vehicles tank, and you couldn't run the vehicle tank dry. Simply by running / driving the vehicle it would automatically top up the swirl pot from the main tank. I really liked the simplicity of the idea and all the benefits it gave. The tank simply bolted to the inside of the chassis leg and was tucked up out of the way. Admittedly on his 4.6ed 129 ambulance so a fair bit of space. Think he did the same on the portaled 109.

Mine were much the same after 8 years and 28K miles - plating quality & longevity leaves a lot to be desired on newer Defenders. My old '84 90 was still on its originals after 22 years and 180K miles and were like new. Went with stainless pistons from Zeus with LR seals. |
