Converting an AC compressor to an air compressor.

[@oliverscorsim]

So I have some notes for anyone doing this because this is by far the best vid on this and I suck with a camera. The bearing race on the pulley side when you split the case it has tabs make sure to line them up😅 I found out the hard way. Also no one has mentioned anywhere about timing it. I didnt know either until I noticed it wasnt moving enough air for what it is and was making alot of noise. When you put the pistons back in move the swash plate all the way to one side so it engages with the bevel gear and look at the rod it should be straight and at tdc. Not sure if this is the way the factory would do it but it seems to have shut mine up and speed it up alot. Drilling the outlet a few drill bits bigger also helped it make more air volume. It fills my 50 gal system from zero to 90psi in about 2min this way before it was about 3min

[@bebophector]

Thank you for the video man, i was unsure if i could convert one but your video is detailed dosent seem to bad.

[@manfordman9112]

I did this to the sanden on my Cherokee a few years ago. I drilled another hole in the housing next to the grease zerk and added a small vent. The compressor gets really hot during use so the pressure in that sealed housing was pushing the grease past the piston seals. Works great though after being vented.

[@bradfordcustoms7588]

Yea I plan to do this before 100% install it.

[@paulgill7222]

How long has it been running and do you use it regularly?

[@oliverscorsim]

@@bradfordcustoms7588 I wouldn't as the crank cases on these are supposed to be at working pressure. This may not sound important but I'm not familiar with these rings. They do look funky so I'd leave it sealed as working pressure is far above what we use them at and the case is made to be under pressure. I know mine moves lots of air and I dont see big losses at higher pressures so I'd say I'm not getting ring flutter. Most of the failures I found were either heat or rings not sealing. All the cases I found of ring failure had vented crank cases. Alot of these types of rings use the pressure on the back to even the pressure differential across the ring pack so it does hold to some things like these for sure. I will say I just recently cut some PVC pipe and glued it on with jb weld between the mounting posts and I have my drain after it. I just leave it cracked so it gets some flow and I can put my hand on it about 2min after a hard run painting a car. I believe these are probably the two best things you can do for it along with a high temp molly grease and drilling the outlet side a few bits bigger (I saw a gain in flow and loss in heat)

[@NN-cw9rb]

Where exactly did you glue the pvc and how big did you drill out the outlet? Thank you for this post. It sounds like you're really familiar with these and how to modify them.

[@mrmotofy]

This looks similar to the Sanden 709 on 97-06 Jeep Wrangler etc and supposedly is 9cfm at 1000rpm. Extreme Outback also has some modified and ready that are similar. They advertise as 8cfm I believe

[@wtfobiden]

Great Video. now i need 1 for my 03 tahoe air ride.

[@2pist]

I'm thinking you could just put a catch basin in the pressure side to catch the oil, then have a valve on a timer that blows the oil in the vacuum line every so often.

[@FireCrowsWorkshop]

Is there any update on performance and longevity of this setup? I’m very curious

[@VanwithTim]

great video ---- instead of grease, how abaout gear oil ?

[@madhouse7743]

Nice workbench dude! Ha ha, great video btw, thanks.

[@BenParker-tt2qm]

Awesome video, one question is why connect the inlet to the intercooler? Is it because the compressor can’t draw it’s own air in or just for cooling purposes?

[@richardmauch1042]

So why couldn’t you just block of the head side with the 1/4-20 and fill other side with atf? That would keep it cool and you could tap a drain so that you can service it now and again? Has anyone tried it? I’m just hung up on the grease part.

[@garrettscott4094]

I'm gonna need to see the project this is getting mounted to.

[@bradfordcustoms7588]

Been crazy busy with work but when I find spare time I’ll try and get an update video out on the truck I’m building. 79 f250 crew cab on a 2011 f250 chassis. Getting a compound turbo 6.7 cummins and will be on air ride and 35s. Should air out and sit on the tires then air up 10-12” to drive turn and tow

[@CaptainDestructo82]

Since you’ve blocked the oil pass through do you not need to have an oil catch inline? I’m looking to do something like this to run air ride on my town car

[@grisby6484]

I've just put a few drops of Aircompressor oil in the foam intake filter aver few trips. Never ever had an issue even filling up 8-12 of mi friends 44' super shapers in a row.

[@MIKEH.777]

I found your video to be very helpful. I'm getting ready to buy a a/c unit and I was wondering if that works with all of them. And when you convert them into air compressors will the clutch kick on and off stopping the air from exceeding the pressure of the tank. Or do I have to get something else to do that . Keep up the great videos you do a fantastic job on them . God Bless you and your family. 💪🏼💯👍👍🙏🙏✌😊✌

[@bradfordcustoms7588]

Thanks I appreciate it. You will need to wire in a pressure switch at the tank to controls a relay that powers the clutch on and off.

[@mrmotofy]

Just search for a 12v pressure switch. 90-120 are very common. 1/4 NPT is very common otherwise 1/8 NPT

[@robturner7024]

You can convert most all compressors but it’s hard connecting to suction and discharge lines on some so the sanden and York are most peoples choice

[@pigidly]

Could this be done with the LT1 94-96 smog air pump? Some people cancel that pump… I would use it to power my bags. My ac work on my car and I need it.

[@robinrochan9301]

Hi very nice video I learnt so much from you but i think if you will pout oil in place of Greece is will much better 😉 thanks

[@bradfordcustoms7588]

Yea but then I have to constantly add oil and then catch the oil from the compressed air, then drain that oil and buy more. Grease is easier and less maintenance and has been proven to work well. We will see tho. If it dosnt work I’ll go back to the junk yard and get another and try oil

[@dansw0rkshop]

In your analysis of CFM around the 10:35 mark, you didn't make any mention of pressure. Was the comparison of this compressor vs the cheap store bought one both at zero psi? 60psi?

[@bradfordcustoms7588]

Full disclosure I was winging those calculations and have no idea. I’m sure there is a formula for it but that I do not know.

[@bradfordcustoms7588]

I attempted to converted the pump cc to cfm but did not factor in the exponential growth of psi. So just assume I’m an idiot and was talking out my butt at that point lol several people have brought this to my attention and I’m not smart enough to figure that part out

[@dansw0rkshop]

@@bradfordcustoms7588 Thanks for the reply! I wonder if it's just a matter of factoring it by a compression ratio. Such as when you do a compression test on an engine it will never be higher than a certain PSI.

[@TEAMPHY6]

Makes me want to see if a dual ac compressor would fit, so I don't have to give up air conditioning

[@gatordave6629]

Been wanting to modify my air compressor in my garage so I can have enough air to use a sand blaster I'm thinking of taking 3 car compressors and hopefully that will fill my 60 gallon tank fast

Theoretically that should give you almost 30cfm
