Why not use gear oil ?
Built 2 of these five years ago. Installed on c4500 for air ride still on there and second in tool box as a spare incase of failure. Two tips regarding grease. 1st put your grease zert into the oil plug you pulled out then just screw it back in. 2nd only use Redline grease it has a crazy high temp drop point. I have 25k on my compress without failure. Maybe it doesn't failure cause I bring a spare.
If you coat your tap in grease it will collect most of the shavings making clean up just that much easier.
You are absolutely right! I totally forgot about doing that. Thanks for leaving a great tip!
And then clean it up with a shop rag so that the next tech that gets that rag slices there hands up on the metal shavings left over from cleaning 😂
Old post I know but you took the words right out of my mouth , using both techniques here would had been perfect,
Good video, thank you
I wish you posted this a day earlier. I just removed the compressor yesterday and installed a Dorman idler pully in place of
Well .. you could always convert it and swap it back in. Not too late .. except for the idler pulley maybe. 😀 . You didn't need the pulley, all you had to do is buy a new belt for a non-AC Jeep.
You are my hero, a six year old could do this. You could draw eyes and a smile on your gloves lol.
Glad the video helped you! I may do the eyes and smile the next time I wear gloves. 😀
another trick to catch all the shavings...slather up the tap with grease...as it cuts...the grease collects the shavings and will take em with the tap when you back it back out
Very very very cool...I wonder if you could use non-detergent air compressor oil in the crankcase/swashplate area instead of grease
i feel like you could add a fill and drain plug and make it an oil unit after you add the 1/4 in plug
What you could’ve done instead of trying to drill that out it’s just kept that side off pull the plug out of the center of the back of that housing and use that for your pressure discharge
Have you considered plugging that hole and using engine oil or light gear lube instead of grease?
Yes, I was thinking gear oil or bar and chain oil - something thin enough to move around the “crankcase” to keep everything coated but still thick enough not to work its way past the piston O rings and into the air chambers?
Hey power addict
Where can i but that oil source fitting u was talking bout
That connected that lil air filter
Any reason not to just fill the whole top with grease in addition to packing it?
My sanden compressor seized up today, fortunately it happened in the driveway after I got home. It lasted about a hundred tires or so (6 months of heavy use). I'm gonna do an autopsy and try to figure out what went wrong. Fortunately these compressors are cheap and plentiful. I'll convert another one this week. Just a word to the wise, always bring a backup air source.
Thanks for another great video.
PS. Pair this bad boy with a bicycle shifter throttle set and have the fastest air on the trail 👍
You are welcome! Glad you enjoyed the video! Yep, I have a hand throttle ready to be installed 😀😀👍
Can you elaborate on the shifter? What's the use?
Loved the conversion.. Thanks.
Do you have a video on removing an AC Compressor from a 2000 TJ 4L 6IL. My compressor is under the power steering pump drivers side. Thanks again. - Vince -
Nope, sorry no video on the TJ.
Excellent video! That discharge port is on the high pressure side so I wouldn't worry about it too much. The air on that side is more dense so that restriction will look a lot "smaller", especially so if you are running a system around 90 psi for any tools or air lockers. 90 psi is around six Bar/six atmospheres, to give an idea about the density.
You plugged one hole to the crankcase side... is there a second hole? How would refrigerant and lubricant originally have flowed through to that side of the case? I would not expect that such a tiny hole would provide the crankcase side with sufficient lubrication without a regular flow of lubricant. If you were to use an air oiler type system, how would you promote flow through the crankcase side?
Just did some googling... Sanden has a couple valuable PDFs in the results including a service guide! The other document is titled "A/C COMPRESSOR GUIDE AND PRACTICAL TIPS". It lists common failure modes for each type of Sanden compressor!
Thanks in advance!
Edit with another thought... air oil is quite thin stuff. I assume it would slosh around and provide cooling for all the components and bring that heat to the case. Grease may or may not provide that function. If I were to build a system such as this, with a good supply of air oil, I think a filter at the output of the compressor would catch most of the oil with some water, and a filter after a cooling device would catch a lot of water with some oil. I'll have to try that some day.
Thanks for the video. What if you put oil and a vent in the back side of the compressor? Wouldn't that be separated from the compressed air side?
I was thinking the same thing, put in fill and drain plugs and a vent then fill it about a third to half the way full of 90 weight. I would think that would help keep it cool also.
@@jesusisalive3227 Jesus is alive indeed. I hadn't got my hands on a ac compressor yet. But I want to take one apart and see if I can do that. I was thinking maybe something like 30 weight oil.
@@jesusisalive3227 Seems like the parts will be moving pretty fast thick oil might produce a little drag??
The small hole is the out put?
How about the cylinders where the actual heat is generated? The cylinders will seize up without lube.
I've used that compressor a lot since I released these videos. I've had no issues at all.
So what i find interesting is people say you cant run the newer ac compressors cause they're cooled from the ac gas.the york ones are hard to find so this seems like a better option. Is the one you used oil lubricated from the beginning or is your method apllicable to most compressors?
It was a AC compressor I pulled off of a Cherokee XJ. I have ran this compressor quite a bit and I haven't had any "overheating" issues. The air it outputs does get the fittings slightly hot. It still runs fine after airing up many tires, and ran a few small air tools. I'll eventually pull it apart and check the grease and re-grease if needed.
im curious, i know it would be additional work but what if you installed an oil line and drain, and used the engines oil pump to keep everything lubricated?
The pistons don't seal that well. It would pump oil into the air line and then into your tires. That's why when people convert these they use the grease method like I did or an air tool oiler just after the intake air filter.
how much air pressure will your setup make? enough to inflate a tire or run an air tool? or is it a max of 10 psi?
Tires and air tools .. no problem 👍
I don't recommend running tools on this setup, at least not for long. This compressor will get hot under extended use.
It will make 120 shop air no problem.
It will do hundreds of psi...but the pressure switch keeps it at say 120psi
how much pressure can it generate, I planning to do install is as air supply to a clutch booster. I'm going to put an air tank as well to store pressurized air.
I honestly have no idea. I've never tested to see the max pressure.
So I've got air coming back out of the air intake/suction side. What could this be. I've got the sanden sd7 variant. And just have a filter on the suction side. Should I add a check valve to keep the back flow from coming back in
Yes, you need to watch the rest of the build videos for the complete system. There is a check valve after the compressor.
I would have found a brass fitting to screw in and tapped it for the zerk fitting then screwed it together
If it works ... go for it.
I want to do this but retain my AC. I know they make kits for adding a 2nd alternator but i haven't found anything for a 2nd compressor
There isn't a kit that I know of. I did see a way to have both AC and an on-board air compressor. I need to get some parts together to figure it out. Make sure you subscribe so you don't miss the video when I do figure it out and release the video.
@@Poweraddicts lol will do. I don't imagine you'd be doing it on a 5.3 v8 vortec? XD
what about just filling it a third of the way with 90 weight?
Gotta be pag oil
@@siegert726
Im no longer using it with the ac system so im pretty sure any quality oil will work.
I have a question. Just installed one. First time running it. It seems as the compressor gets really hot is that usual?
Yes it does get pretty hot. So that is normal.
@@Poweraddicts also I have a lot of oil coming out of my separator is that normal as well? I used it yesterday after the trail and filled up my 38s in great time. Just want to make sure all the oil coming out isn’t going to ruin the compressor.
How much pressure do you reckon this could deliver?
I personally have no idea. I have no need for high pressure so I have no reason to push it. Thanks for dropping's in!
Hey bro do you need to put grease around the piston rings? And if so how does it stay there once all is moving?
Could this be used to supply air for a train horn?
I'm sure it could.
So is this still going? Any issues or problems? I'm going to build one for air ride.
I used it a couple of days ago and today. It is doing just fine. I recommend checking the grease periodically if its used a lot. There is the option of running the external oiler instead of greasing the internals. I'm happy with it.
@@Poweraddicts Great! Thanks!
What kind of oil to use?
In this video I used grease. No oil needed.
How much pressure it will get
My pressure switch is set to cut on at 95psi and cut off at 125psi. They are capable of much more but there is no need in running high pressure. This is more than enough to run small air tools if needed.
Well not true really higher pressure means more capacity which is generally good
Lol your jeep has ac?
not anymore!
LOL .. actually it never did. I pulled that compressor off of a Cherokee XJ 😀
One thing for sure, this will not work for very long. If this would work , for any length of time, it would be done this way from the factory.
I've used it quite a lot. No issues at all. I do some HVAC as part of my full time job. I know that the oil is part of the refrigerant in an automotive set up. In a residential and commercial HVAC units the oil is in the crank case of the compressor not in the refrigerant. So .. yes .. it is working just fine. I've ran small air tools and pumped up many tires large and small. I've used this to pump up tires more than my upright 60-gallon 2 -stage 5HP shop compressor. It pumps my 35s from flat to running pressure in under 2 minutes. When I build them like this I pull it apart maybe once or twice a year to clean the internals and regrease. I have not pulled the one in this video apart yet to perform any maintenance on it, there are still no issues at all and it performs great. Here is the video link where I demonstrated it. Have a great day! ua-cam.com/video/m8a6Wx1AMNM/v-deo.html
You have no clue what you're talking about. This has been done for years by many.
This is modifying and repurposing the compressor for a slightly different function of air not oil.
There's companies that modify new ones and sell em for this purpose
So it won't work unless the factory does it 1st?
It's easy to see that your a follower and not a leader , these pumps modified like this last years , many years if you do the maintenance if you follow everything by the "book" you will only be as brite as the numbnut that wrote the book. Just because "he" thought of it 1st doesn't mean it can't be modified for improvement or used for something different
