Craftsman 3 gal, 125 PSI Air Compressor keeps running
I'm not sure if this is the correct forum - not gas powered - but it is shop equipment. I went to use my120 Volt, electric powered, Craftsman 3 gallon, 125 PSI max air compressor yesterday, it worked fine about 2 weeks ago. It keeps on running and hits a pressure of only about 75 PSI according to the gauge. It doesn't get any higher pressure to reach the motor cut-off speed. I looked close with my 62 year old eyes and could only find that air is blowing out of what appears to be 2 vent holes at the top of the oil filler nut, and I'm pretty sure that this is not normal. Do you think I blew a gasket in the head? Thanks for any advice. I usually repair all my equipment myself and don't think it's worth returning to Sears for repair since I bought just about 3 years ago for $99. If air is blowing out of the oil filler hole it is most likely that the piston rings are worn or the crankcase is overfilled with oil. If worn rings it would not be worth messing with. What is the model number of this unit? Thanks for the reply. This is Craftsman Model No. 921.153101 and I just dug the receipt out of my folder and it was purchased 1/31/2008 so it's way out of even the extra year I purchased for $15 at that time. I checked at sears.com and this exact unit is on sale now for $79.99. It looks like I need a new compressor and I'd like to upgrade to a larger unit on wheels so I could move it around a lot easier. Do you have any opinions on whether to buy a horizontal or vertical tank or horsepower preferences? They show quite a few different models and other brands besides Craftsman on the sears website. Also, do you have any opinion on the compressors sold by Harbor Freight? They have a store nearby in New Jersey and I am in that area often so I wouldn't have to pay shipping charges. I just noticed your AIR COMPRESSOR INFORMATION post on this forum after I sent above reply and it answers a lot of what I asked about. Ya, purchase a unit based on CFM capacity @ 90 psi, not gallons! The gallons capacity of an air receiver tank dictates the running time of the compressor between cycles, not how much air you get. Some genius in the marketing department got a brain wave when they realized they could put a bigger tank on a small compressor unit for cheap and then convince people they somehow got more compressor capacity. And yes, you will get a bit more stored air....... about five seconds worth if that! Tank size can make a difference but a lot depends on how much bigger the tank is and what the use will be. What all are you wanting your new compressor to do? Nail guns, impacts, tire inflation - don't require a lot of cfm but sanders and paint guns require a lot. While a sander will still work [somewhat] at reduced pressure, a paint gun will not.
