Would you rebuild this craftsman compressor?

I have had this 60 gallon "oil free," claimed 6hp compressor for a long time. It is a craftsman model number 919.152813. Recently it started getting louder and now takes forever to build pressure. I seen online where I can get a rod with the piston and new cylinder sleeve for $50. Which I would need two of for the two cylinders. Would you guys drop $100 into trying to fix this compressor or would you cut your losses? It is plenty to run all the tools that I use back when it worked right. I am guessing that these "oiless" compressors are looked down on in the compressor world? So my question is, worth rebuilding or save for an upgrade?

NO.
I had one and it may have been the same model. When the motor went south I donated the tank to a buddy who teaches aeronautics for a test cylinder for some of the rocket engines they build. The noise alone was enough to keep me from resurrecting it.
930 has the right idea.

If I saw a NEW 60 gallon oil less compressor on sale at (insert box store here) for $100 I would keep on walking even if I desperately needed a compressor. To me they are only worth their weight in scrap metal. I guess you could use one for an air stapler or pin nailer... A direct drive oiled compressor would be a step up from an oil less, and even that compressor is fairly cheap. As others have said, get one with a separate motor, pump, and a belt that connects the two. If you only use it very seldom then maybe a direct drive would be acceptable. Most oil less units create more noise than air.

I was afraid of these answers, lol! Wonder if I could mount a plate on this tank and buy a pump and motor from harborfreight?

Any way you could retro fit a new compressor pump and motor onto the old tank?

I would probably be more concerned keeping the old tank than rebuilding the old compressor. It is probably time to let go.

I rebuilt my oilless twin cman pro with rod/piston and seal kit from amazon for $75 back in 2013, still working great.

I am going to say no too. Parts are easier to get today but some of it depends on age and the rest of the general condition. The last used cheap comp I worked on caused me a lot of grief and I should have bought a new one. The only piece I didn't repair was the motor. Fix one thing and the next one popped up. It all works now and I had donor parts but I got a day and a half in it, took it to the job 2 or 3 times and lost a days work when I needed it.

A 60 gallon oil-less? Good Lord, are you deaf now?
I used to have mine in the basement and piped it up to the garage. I'm OK, but the wife and cat are now deaf. Actually the cat would take off running if he saw me walking towards the Craftsman compressor. Not so with my new oiled compressor.

Good idea, but only if you first take a look inside of the tank to check on the rust damage. All tanks will have rust, but the critical item is how deep is the pitting.
The 2-cyl HF pump is actually quite good (at least mine is). It is relatively quiet and makes 140psi easy.
The only issue to be aware of the flywheel balance; mine was way out of spec so I'd recommend checking it before assembly.

I gave away my working oil less compressor because of the noise.

My neighbor is a retired GM mechanic. He says , "buying good tools only hurts once, using poor quality tools hurts every time you pick them up"

Don't you think buying the parts and building a compressor is more expensive than just going out and buying a new compressor? Isn't that like buying all the parts to build a car and then assembling the car yourself? I have a funny feeling that by the time he buys the pump, the motor, the belt, the guard, the pressure safety switch, etc, he will have as much into it, if not more, than if he were to buy a new compressor. Anyway, that is my opinion be it right or wrong.

If you were happy with the compressor before why dump it?
First the parts that are bad may just be the rings around the pistons. In some models you can replace just the rings (they technically aren't rings but that makes for an easy description). The compressor lasted 12 years and with that rebuild should be basically good as new. I wouldn't worry about tank rot given the age and assuming you kept it drained.

Looking on ebay I see a Devilbiss kit for $34/cylinder (compatible with the Sears part #) . The rings are about $8 each. So you might be as little as $20 if you cylinders are still smooth or $70 for a more extensive rebuild. I also see some kits that include the cylinder, ring and seals but refuse the piston. Those are $27/each (I didn't verify the part compatability).

I go with capt crush.
I would at least pull the heads and check the reeds.
They are easy and cheap to replace.

Mine also burnt up and I kept it for years intending to make a smoker out of it. Lately, I've been paying quite a bit for sandblasting so I made a pressure blaster out of it. I'm putting together a post of the project.

I took the cover off today. The plastic fan was broken into about 40 pieces. I can spin the crank with the rods and pistons with one finger no problem. The whole time the pistons move they make a horrible squealing noise. I am going to start saving for a real compressor and send this one to the compressor grave yard.

Good point. A 'better' quality 5hp motor and the needed sheaves and belts do add up but still should be less than a complete unit, even if buying something like the HF 5hp/60gal unit at $800. I swapped an HF pump onto an old CH unit and it works very well.
For the OP's situation, the internal condition of the tank is critical and some mechanical skills are required.

i went through this over last winter, the CM oilless ive had since '87 stopped compressing. i knew what was wrong, (ive been through this before)
i debated just tossing in the towel and buying a new compressor.
since i dont have 220 to the garage, i figured in what it would cost to trench, conduit, wire, breakers, sub panel, ect ect. PLUS buying the ew compressor

i dont use that much air, most of what i use in the garage are electric powered tools, (grinders/sanders) if i NEED air it's for an impact, or inflating tires....
i have air in my service truck if i need more air..

i ended up just fixing the old compressor.... and plumbed in a new intake filter to replace the scrap of foam CM originally used.....

If a guy can fix something for cheap, quick, saves real money or time I am all over it. If I have to invest in used speculation not so much. If I am saving or making 30 an hour, even 20 or so in some cases it may be worth it. Not that I really track that but I try to put some kind of value on it. At the end of the day if I save a couple hundred or add to the equity then it may be worth it.

I would check for the price of the o-rings plus the fan. Get it working and you can probably sell it for $200+. As is its worth a few bucks at best. Alternatively give it to someone who is just starting out and sorry on cash. You'll do them a favor while being out no more than if you trashed it.

I had the Devilbiss equivilent. It was really noisy, but worked very well for about 5 years. I started using it several hours a day. Rebuilt it at about 6 years. Worked great for another two. I really liked it for painting, as you did not have to worry about oil in the line. But, it started failing again. Next rebuild lasted about a month. Thought it was devective pistons, and replaced them; gone again in a few days.

Finally gave up. Found a great deal on an 80 gallon Dayton with a new pump on it. It wiil outlast me.
