Just a quick question as Im on my way out the door, I have a Craftsman model No 919.165610

Cant seem to get a steady enough pressure to run a grinder or DA, anyone messed with this variety compressor and is it worth me messing with any longer. Maybe I just need to keep the tank and get a different compressor.

I want to be able to do most anything I want to do at home including run a sandblaster again.

I dont mind putting some money into it to get it where it needs to be but maybe there is nothing than can help this thing do what I want it to do and I dont want to piss away any more money.

Any suggestion welcome

How 'bout some specs and photos?

I see lots of compressors and related parts on Craigslist every day. I am trying to find a replacement tank for a Sears compressor I have. Mine has a pin hole leak and so I won't use it anymore.

That is an oilless compressor, in new condition it should be big enough for an air grinder, but oilless compressors have plastic follower rings, they wear out. There are reasons the old timers used oil.....

Might be he will post them tonight, I have all of the covers and I removed the tube that connects one cylinder to the next just to see if I can feel what sort of air it is making, funny thing is one cylinder is making so much air I cant possibly keep it contained with my finger and the other is sucking in air.

Not sure how it works, seems like that tube I removed carries the air over to the other cylinder and from that cylinder it is forced down into the tank.

Any clarification on this would be nice.

If its worth putting money into it than any further info on this would be helpful I am sure, not sure what it is you are reffering  to

Those tools seem to take a lot of CFM to get them to run.I have a 60 gallon tank and I can run it out of air rather quickly with an angle die grinder.The tool should say how much CFM it takes to run it.The compressor will also say how much CFM it will put out at what PSI.

Here is one source for parts. The parts diagram should help.

The oilless jobs are pretty much short life consumer grade. Maybe a real compressor on that tank is a good idea.

Thanks, yes I do have this, Id like to hear more about how exactly it works, I understand that it forces compressed air into the tank, like to find out why one cylinder is compressing air and then running it over to the other cylinder which is sucking air.

Like to find out what wears and how to look for the wear, anything else that might help

Im sure Oily will post some pict. soon enough

I don't know alot about compressors yet. Maybe one of the cylinders has a bad reed valve ? I am just learning about them. One I have leaks air from a pin hole in the tank. One was givin to me that the piston is broke in half at the wrist pin. My third and smallest runs ok, it's just too small for HD jobs. I missed out on a couple of free ones because I called too late.

Pictures!

I dont think this version has reed valves but thanks

The Spec. sheet shows two different strokes and two different pressures, and the tank says two stage.
So I think the the low pressure piston draws in air and pushes it to the high pressure piston. In other words
one cylinder feeds air to the other cylinder.
