onboard air using A/C compressor

[arkfj40]

Gidday, where abouts can i get the parts from, all the valves lines switch's etc. im in chch

[wjw]

Theres a hydrulics place down near wigram, on the road that loops from the motorway round to the other side of the overbridge. Can't think what its name is tho...

And up the Carmen Rd end of Waterloo Rd is CTS ( I think that's the name) about opposite the rifle club grounds. That's where I get all my fittings and hose from. They do trade discount too if you ask.

[flyingbrick]

Oh shit.

Went to Norgren store.

basically quoted me over 600 for just the oiler, seperator and pressure switch.. and the guy behind hte counter had no idea wtf i was on about when i said i wanted one that came on at like 80 and off at 120ish.

hmmn, i should know this one.. went to a training course about it last week actually.. hmmmn.. im not sure...

and then i got the card for their systems design expert or something..

[flyingbrick]

seen all those I've got bids in on some hose and some air tools

that oiler is ugly as shit imo. really want a stand alone oiler (half that size) that wont take up so much room. Norgren had them.. at $120 each.

Took the truck into CoolCar and had them suck what was left of the refrigerant out. He said it was R12?.. the bad one. So i feel good now for not poisoning the environment.
Removal was FREE.

Thanks I think its hydralink down by addington racecourse, i'll give them a go.

I fount CTS cheaper in Waterloo Rd for the fittings etc, much cheaper.

I will put my name down as a spectator and future recipient.. added to my "to do to the 40" list.

Any specific AC pumps to look out for?

[flyingbrick]

if you dont have an AC pump in your engine bay already.. and you are gonna have to make up mounting brackets etc... buy that self oiler in the FS section.

Ya beat me to it ...

One way to get a lot of the bits that ya need is to pick up something like this



The moter and compressor is unwanted but you use everything else. Supercheap and the likes often have them on special for $150 ish

[Thirsty6]

so is anyone still keen to take an afternoon to have a play around modifying a AC compressor in welly?

Wife and i are all moved to the new place...only problem is the hilux wont fit in the new garage...stink aye!

[petefj40]

can ya run it without the cut off switch ??

I only ask coz my switch in the 80 when ya turn it on, the aircon will bring the revs up about 500rpm, so if ya could run it manually and then turn it off, then that would be fine for me, do ya need a reservoir tank also or just run it straight off the pump ??

Best to have the switch, can be done without it but not best too... also no, you don't need a tank but can if you want to.

You don't need a tank, but if you have the space I'd suggest having one.
The advantages?
If you have air lockers you can do away with it's small air pump and use the on board air tank instead. Other useless items can be plumbed up to it to, like air horns.

Loks like a nice sized tank Pete, where did you get that?

Cheers.
But like most things on my truck, it's a bit overkill.
I wouldn't suggest using something of this size. Half the size would do fine.
I think someone earlier mentioned where you can purchase a tank pretty cheaply.
You could adapt an empty fire extinguisher to do the job.

As my truck didn't come with air con I needed a switch to turn the air on/off. So I ended up using the ARB switch.

We will use this thread to advise where and when, any of the wellington crew, or anyone else for that matter, that want to see how it is done are more than welcome to come along, if we get a big group, then we may use Rallywoods....

Did this go ahead?
If so are there any pictures of the build?

[flyingbrick]

thought i'd bump this up a bit.

Latest issue of ausie 4wd action that i bought had a massive air compressor comparison. They tested basically all that are available from that real cheap black plastic rugby ball shaped power air thing (supercheap air compressor) right up to the multi thousand dollar warn air compressors. I don't have the magazine with me ATM but incredibly the fastest pump there was the Endless air engine driven pump- which they stated was made from second hand and modified ac pumps.....which retailed at something crazy cheap like $400

They made a good point however about the temperature of the compressed air coming from the pump- and said that only HIGH TEMP air house should be used- and even had pics of a normal air hose melted to shit during their test on the AC pump.

Have any of you guys had this problem? I'm kinda wishing i'd left the aluminum hard line a bit longer on mine before cutting/pulling the pump out.

PS, have got my pump out and am fitting 90 degree brass elbows to the in/out ports and then nice barbed fittings to take the air hose (replicating what endless air do) its gonna be sooooo sweeeeeeet.

supercheap currently has air compressors for $119 too which is fkkn great for anyone wanting to go endless air- it gives you the tank, pressure switch, over pressure release valve and gauges + tons of random fittings etc.

Went to butterfly creek today with the gf and decided on the way home to pop in at supercheap to see when the deal ran out- today is the last day (i was hoping it would run next week) so i was forced to get one on the spot.

I suggest anyone wanting one get in there ASAP. Deal actually expired yesterday but the product is so popular its had an extension of one day.



* For general light duties & tasks around the home
* 2HP motor
* 21 Litre tank capacity
* Direct drive design
* 6 - 8 BAR operating pressure
* 77L/min air delivery

mines all stripped. Must look like a total f-wit to everyone around. It didn't even get plugged into the wall.

For anyone still interested in taking this route- this is what you get

-Adjustable pressure switch with gauge to show tank pressure and on-off switch
-One way valve (so air does not leak back through the compressor)
-An adjustable pressure regulator with its own pressure gauge (I wont be using this)
-An air filter (will be using it on the AC compressors inlet)
-The air tank.
-two ball-type taps- one on the drain and one which could be used anyplace you want
-an over-pressure safety release valve

[flyingbrick]

Wow.. this thread is quiet. Is it me? lol.

So anyway. Pulled my AC pump out.

Stripped it all down and gave everything a good clean/media blast. These things are beautiful inside.









I milled down the surface where the in/out pipes bolt down until the ID of the holes stepped down small enough to be drilled out and tapped with the standard air fitting 1/4" BSPT. So some nice fittings could be used.



I then started to look at ways of reducing the units lube needs. I still want to run an in-line oiler but this could never supply enough oil for this pump as is- IMO.

Currently the pump has aluminum pistons with steel piston rungs running in steel sleeves.

I was going to machine up my own rings out of teflon when Vvega came forwards with a better idea- phone the professionals.

I've now machined each piston ring groove out to accept teflon cap seals.
The seals come with rubber energizer o-rings which are being replaced with Viton O-rings that have a heat rating of 200 degrees rather than the rubber rings 100.

More pics when those are installed on each piston.

Also- the unit has four roller bearings. Two to take axial load and two thrust bearings. The DE and NDE housings have little oil ports which allow the air/oil mix to be blown/sucked through the bearings. I'm fairly sure at this stage that I'll block these ports off and fit external grease nipples. There is no point having them there really since there will be so little oil in the air stream anyway.

Anyways. Hope you liked the pics of what they look like inside.

I'm watching, even went out and bought one of those compressors after reading your post.

The whole electrics on that compressor would be 240v correct? How do you plan to get around that?

Here's a thread I've just found which interested me

hehe im watch tht theard too

[Andrew1706]

I was just about to reply that I'm using my stock AC pump since mine doesn't work anymore and I've never used it

if either of you two are planning on doing this with your 80s, then take lots of pics and notes

so I can steal them, as when my motor goes back in, the air con is not gonna be used as it was shite and leaked anyways.

so plumbing it for air, I want to do

The pressure switching mechanisim is just that, a switch. It is rated for up to 240 volts use, but it will never know the difference if you put a 12 or 24 volt supply across it.

Sweet as, I thought so

[kiwipete]

I see in today's junk mailer from Super Cheap that they are doing the compressor (2Hp), hose (20m) and fittings (5 piece coupler set) for $149.00

That's gotta be worth looking at for any one interested.

[flyingbrick]

shit yes.

Just $20 more than i paid and you get hose and fittings...... good deal.

bugger


anyways. Some useful information. There has been talk about using a relay and bla bla to switch the pump on and off.

I've found a better solution (for the nis safari).

when you remove the air con system- pipes/ etc you will find on the left side of the engine bay an aluminum canister/tank thing. It has some kinda sensor- pressure? plugged into it.

When i pulled my system out i pulled the sensor from its home and left it dangling in the engine bay. When i tired to turn my AC pump on- It wouldnt go. So i cut the wires to the sensor and touched them together- the clutch engaged and it fired oil everywhere.

So i'll be running those two wires back to my pressure switch. They are obviously low current etc so

[Heath]

pretty sure the sanden compressors can be run as a grease filled unit and not need an oiler. Cant find the link though (sorry)

[flyingbrick]

It just seemed easier to use something that already has brakets and belts etc setup for my car.
