Home build Endless air & Air operated winch

Hi Twigiee,
I'm curious about what you've done! Let me know if I have got this right... You've installed an additional A/C compressor and it is modified somehow to operate as an air compressor? That sounds tops! Where might I find more info on this and do you need a high level of mechanical expertise or special tools to do it? I have a 1FZ-FE 80 Series.

How quick could you pump a 33" tire from say 20psi to 36psi with it?

Cheers
Scoey!

I can remember my Dad had a spark plug pump , how you used it was take out 1 spark plug and screw the fitting on one end of the small air hose, connect it to the tyre valve and start the engine and it pumped up tyres in no time , No good for diesels of course , Have not seen them on the market for years.

Twiggy, have used an air winch on many occasions to haul in underground power cable. If i remember correctly the five to unit we had weighed about 380 KG and required a minimum of 250cfm to drive it. Might be something more suited out there but My thoughts would be that it would be a fairly cumberspome unit!!

Hi Twiggie. As has already been posted, there's heaps of info on this forum about this style of compressor. I've had one for a couple of years now and it gets heaps of work. Tractor tyres are no problem, it will run a rattle gun and I've even done spray painting with it. Heat is the biggest problem with this unit. To overcome this I used high pressure a/c hoses and fittings to a fair sized air tank to cool the air. A 2nd hand air tank off a truck is the ideal size, and solved my problem of blowing hoses every 5 minutes. The other problem is lubrication, and I installed a grease nipple and pump it full of high temp grease. Seems to work ok. Cheers Ferris.

Hiya Twigiee,,,

I have taken a ticket for you to install one of these endless air setups in my car..
I have seen the endless ones work and they make my MaxAir look like a convicts fart....
So if you have time i would like you to fly down to my place over Easter and install it....
How does that sound??... Pretty good!!! Great... Seeya then... hehehehe...

Hi Twigiee, do you have any pics that you are willing to share? How is the compressor driven ie by one belt, now running both? Cheers

A Mate had a spare aircon compressor on his 45 Series Troopy. He used to pump up all his 4 tyres and be helping someone else by the time I was finishing my 1st tyre with my crappy Hurricane compressor.

I've had a look in my GQ and it would take someone more creative and mechanical than i to find room under the bonnet lol. would love to have one tho.

Idealy, a piston type compressor should be used in preferance to a rotary one: ie a York instead of a Sanden (depending on space available to mount it). Yorks were used on early Fords & Chryslers & a lot of trucks. Try the wreckers for one.They can be mounted verticle or horizontal, & don't need a seperate lube system as they have their sump seperated from the barrel/piston.

Sarg - your exactly right about the york compressors, no room though.

I found an interesting forum discussion with some photos of a sanden 508 in a turbo 1hz - slightly different to the way that i've done it. Its at:

Hi Guys, I set my first air con compressor up about 12 years ago (saw someone else with one) and I never had to replace it. The Sandens are made exrtemely well like most others and use Tefflon rings on the pistons. Several mates have seen mine and done likewise. We simply accesed the compressor via the nut in the body of the pump (about 14mm) and gave it a good squirt of WD40 or similar every so often. Never had a pump fail doing it this way and most of the pumps came from the tip to start with. I wouldn't fill the pump with grease as I think it will eventually find it's way into the air line unless you make some kind of trap as the pumps are designed to circulate oil & refridgerant together thoughout the air con system. This is one reason the York pumps are better but a lot heavier. I have a 350 Chev in my 80 Series and there is no room for a second compressor so I have almost finished building a portable version. I have a small 4 stroke aluminium stationary engine with the compressor on one side and and altenator on the other. So far in testing it works like a charm. A charger and compressor in one.
For the cut off switch I use the one supplied by ARB (about $45) for their compressors as it cuts in at 80psi and cuts out again at 100- 110psi. I found with my car running at 1200 rpm the compressor would out run or out pump an 8mm air line and while I was pumping up the tyres I could hear the pump cycling on and off. A tank of about 150mm X 500mm is more than enough and you can get by with no tank at all. This system is cheap if you can do it yourself, reliable and faster than ANY electric pump on the market. Hope this helps, Stuart.
