I have an old Craftsman 2 hp. 220 volt Compressor/Sprayer. It works GREAT but I need to know how much oil to put in the 2 piston compressor? I found a model number 919.15678. Thank You in advance.
I'd get rid of this old compressor before it blows up like mine did...they're not safe, check it out at:http://s1297.photobucket.com/user/magnam...I'd get rid of this old compressor before it blows up like mine did...they're not safe, check it out at: http://s1297.photobucket.com/user/magnamanV65/library/
Did you get hurt? That must have been VERY LOUD. I am in the southern AZ desert where the humidity is very low and am digilent about draining the tank daily. I have no choice but to keep using that old compressor. The economy has kept me financially embarassed. What part of the country are you in? Thanks for the advice & the scary pictures!Did you get hurt? That must have been VERY LOUD.

i'm in Wisconsin but, I could examine the inside of the tank easily now. rust was not the issue here either. After years of 120psi the metal tank stretches and gets thinner then boom! feel the tank when it run, it gets hot. I have a friend who's a metallurgist. Atleast lower your pressure to no higher than 100psi.i'm in Wisconsin but, I could examine the inside of the tank easily now. rust was not the issue here either.

If you have air blowing out of the oil filler cap, I would suspect that the piston rings are shot. The piston rings are supposed to keep the compressed air above the piston, and air seems to be leaking past the piston rings into the crank case.
I've been working on air compressors for a while now and so far haven't found any that give a specific amount of oil to put in the air pump crank case. They all have one of two methods to get the oil to the proper level. First, and my favorite, is a sight glass at the bottom of the crank case. About the size of a quarter, it lets you see how much oil is in the pump as you add it. Usually they have a red center dot which is where you want the oil level. A little over or under is OK but the sight glass should not be completely full or completely empty, both are hard on the pump and drive motor. Another method is a dip stick usually on the end of the fill hole cap. Only bad thing about these is you have to put in some oil, check the oil level with the dip stick, then add more oil and check it with the dip stick until you get to the full mark. Again, not over and only a little under is where you want the oil level.
The only thing I can think it might be is something else is running on that breaker. But for it to snap a 30 amp, whoa. The 5.5 hp motor probably draws 18 amps on start up if not more. But then runs on 12 or 13, so for it to snap a 30 amp, I don't know. The capacitors, you have 2, could be drawing too much. One thing, what is the 30 amp breaker for? Is it 220 volts? Is your comp 220 volts? Check this stuff out. I'm not sure how you test the capacitor, but don't go messing with it, it holds a charge. Hope this helps.
Is there an option for you to run this compressor on 220 volts vs 110 volts??? If so, you may want to convert it by following the re-wire instructions on the motor or wire access plate/instuction book. The reason your compressor won't fire up again after building pressure is the head pressure is to great at restart and 110 household current is not enough to give the power needed to turn the piston. You'll need to replace the plug and have someone run a 220 volt circuit once the conversion is completed.
1.If it has a low oil level, have it refilled to proper level, and restart. 2.If it does not start. Isolate the motor from the compressor, by removing the v-belt. 3. In this manner, we will know where's the trouble. 4. Put power to the motor, and have it started. 5. If the motor start, then it is okey. If the motor just groan and does not start, check the starting capacitor, it may need replacement. 6. Check the compressor if it can be turned (one to two full turns). If it can turned, then, it is okey. Otherwise, check the compressor piston rings. It may need to be replaced. 7. Reassemble your compressor and replace the v-belts. 8. Then, you can plug in to the nearest power outlet and start the compressor.
Most brands of air comperssors are built to work on either 220 or 110 v. I believe that 220 v compressors are more efficient and draw less current and run cooler.
The more expensive compressors have a switch allowing for voltage selection. Still others will have a wiring diagram printed on the motor allowing voltage change by changing jumpers. Most all of the sears compressors that I have repaired were of single voltage with no other way to change except change motor. Do not worry however, you have the better motor. It is easier to convert the outlet plug to 220 by isolating the circuit and installing a 220 v breaker. enjoy

or as low as you can operate it.
oh, it was loud and luckily I was not in it's path across my garage!
