CRAFTSMAN Oil Free Air Compressor Repair / Rebuild



You can view the writeup at http://www.toddfun.com/2012/08/25/craftsman-oil-free-air-compressor-rebuild/
In this video I rebuild my Craftsman 5HP 30gal model 919-165300 oil free air compressor for ~$47 USD. This is a ~12 year old compressor that could no longer get up to press and would have cost over $350 to replace.

You will need a long Torx T20 driver if you don’t want to hack up your cover.

I ordered my repair kit from: http://www.searspartsdirect.com

  1. Good video! Gonna rebuild my later this year. Just picked mine up at a garage sale and am gonna monitor how long it takes to fill up first.

  2. Best to get all your spare parts now. It doesn’t look like Sears will be around much longer although i think many of the compressor parts from other companies/brands. Fit each other very often everyone used Campbell Housefeild pumps and pistons I believe were the go to ? Of course Sears rebranded most of what they sold years ago a salesman gave me their code that was simply the first two numbers of the serial number was the manufacturer of that power tool The guy actually gave me the cheat sheet the salesmen used ! At the time i was looking at a Craftsman mitre saw that was made by Delta but had a different colored plastic housing on it than Delta branded tools that was back in the late 80s early 90s when I started out in the woodworking industry and was outfitting my shop and tool collection things may have changed over the years as i pretty much stopped shopping at the stores due to terrible service and way too often not in inventory as many times the sales staff wold tell me to use Sears .com even that i was in the store with money in my pocket to buy a specific item ? Ironically using their online Application. Was also horrible as most of the times the items were shipped incorrectly including many tools i did not order or pay for ? I used to order tools for a crew of men and very often the freebies would go in my personal tool collection or my sons ? You are correct on watching for that compressor for free and fixing it easily I’m enjoying your videos and did sub like and will share when i can as a supporter of your channel

  3. Have a coleman powermate CL0551509. Need a piston. P/N on the piston is
    048-0103. Any suggestion on compatable replacements parts without
    spending an arm and a leg?

  4. Should have cut the handle off the screw driver and welded the business end to a longer shaft. I think thats what AVE would have done. Im just saying . GOT SHOP?

  5. Hey there, I have the exact same model 919.165310 craftsman and other day it tipped to the side the the muffler (filter retainer) broke. Can I still use the compressor with a broken muffler. If not where can I find a replacement part. Thank you!!!

  6. A few drops of air compressor oil (or non-detergent oil) on the intake every now and again goes a VERY long way for the longevity of the air compressor…they call them oiless…but a tiny bit of lubrication goes a VERY long way.
    Same as a drop or two in your air tools each time you use em to lubricate the sears inside them

  7. I know they are called "Oil-Free" compressors, But I wooda put a drop or two of Oil on that piston ring anyways. The first start-up is always the big moment.
    My Harbor Freight Oilless just shit the bed .. I won't buy another one.. I'm tired of cheap tools. They always crap out when ya need em. Besides, Harbor Freight don't sell parts for it, Nobody does. I'm buying a real oil compressor, they last a life time..

  8. I was able to to use a 7/64 Bondhus ball end driver to remove the shroud bolts. Saved me the hassle of removing the shroud. Thanks for the video!

  9. You destroyed the cover needlessly. My craftsman torx screwdriver worked perfectly. Too bad because now your compressor cover looks like a hacker was at it

  10. oil less compressors fail.
    thx for the fix.
    make sure its environment is clean or you will be doin again w that cover cut up.

  11. I think that the round gasket would actually fit when you install it and it gets smaller within the track that it goes into…

  12. Need help…not sure what it is, but the compressor will not turn on, it will only hum. Is this due to the piston frozen, or is it in the switch.

  13. I have to say that, that was a bonehead move to hack the cover to shit rather than getting the proper tool. Who does that…maybe it's somebody elses workshop that your doing the video in. What better reason to go to the hardware store than to get a new tool.

  14. If you are smart you will never buy oil free compressors ,they are junk ,a oil compressor with minium care will out live most people

  15. Good video. Covers all the questions I would have about the repair. Hopefully parts will still be available if Sears goes under.

  16. Very helpful video but you CAN in fact buy just the teflon ring. It's called a Dac308 and I found it on Ebay. $10. I. case you don't want to put $50 into your old compressor.

  17. hello Todd Harrison I too have the same one and I started to notice that it wouldn't build anymore so did a search and stumble on to your video. so glad I did now I'm able to fix it and not buy another one had this one going on 4 yrs now and its been good to me. also I do understand about being hot because I also live in Az its a little harder to work especially if no A/c even tho I'm from California I don't think i can get use to the heat but im sure I'll manage. I liked the comment from B he said that these had got on fire before being they were oiless I never had the plastic cover on mine this hole time super glad that I haven't had any major problems like that. Well your video was very helpful and thanks for the tips.

  18. If you need to replace the bearing you can grind it off. Apply a little grease and use a socket the size of the inner ring on the bearing. Put into a vice and press it back on.

  19. Completed the job in about 20 min. I bought the compressor used and it was always noisy and took a while to fill up. Now it is very much quieter and the tank fills quickly. I'm so happy to NOT be buying a new compressor.

  20. This vid is a great help. My tank would not fill past 30psi. I took out the sleeve and piston and can literally see daylight past the piston seal. Have a new kit on order including the valve plate. Everything will be new when I'm done!

  21. Just tore one of these down this afternoon that I got for free. The reeds on yours where it looked like a seashell, mine were in 3 separate fingers. One of the thin metal fingers broke off and ruined the raised section where it works. They quit making reeds and reed sandwich plate. I'm so bummed.

  22. Todd, I hate to be critical of your effort but I feel the need to voice my concern about a couple of the things you advocate in your video. First I don’t know if you are aware that there have been a number of lawsuits over homes burning as a result of fires started by Craftsman Oilless Compressors overheating. You may have lucked out with you’re compressor hacking up the cooling shroud the way you did but for someone else doing that could cost them their home or even a life which would be really sad considering for a few dollars I was able to buy a torx driver with a long enough shaft at Home Depot. Secondly, because of the amount of time oilless compressors run at the extreme RPM the do, the part that fails catastrophically the most is the rod bearing. While I don’t advocate replacing the bearing every time you rebuild, in fact because they have to be pressed off and on I don’t replace the bearing unless it shows signs of being damaged. However, I never do a rebuild without thoroughly flushing out the old bearing and repacking it with good quality high temp grease. If you do that every time the bearing should last the life of the compressor, but if you ever do find you need a bearing, I've found that most take a standard 6302 bearing which you can pick up at any auto parts store. Other then those 2 issues, which not saying something about has been eating at me for over a year, the only other thing you’re video didn’t touch on that may need doing is replacing all the reed valves in the head. I found that, while a new cylinder/piston kit always improves the compressors performance, sometimes you need to replace the reeds to make it perform like new again. Personally I do the cylinder/piston kit and repack the bearing on mine every 12-14 months and replace the reeds every other rebuild, but I use mine almost everyday. Sorry again for the criticism but felt for safety reasons I needed to say something….
