oilless air compressor rebuild

As most already know the oil-less air compressors leave some to be desired. I bought one about 5 years ago and have been disappointed with it ever since. Right after another someone posted that theirs dropped a rod mine did the same thing. Given that I could rebuild it for $100 or replace it for $1000 I decided on the former. I will however be saving up my coins to replace the POS in the future.

When you rebuild it check the crank is not bent, about 50% of the bend when the rods let go.
I have seen 100's of them in my shop.
I don't repair the oilless units any more.

It doesn't really have a crank but I assume your talking about what sears calls the eccentric shaft? Really a stupid setup. Very cheap to build I am sure. As much as I use my tools anymore I sure hate to dump a bunch of cash into a compressor. The tank isn't even built to where it will accept a new motor and pump setup.

I already rebuilt it. My web server seems to be having issue right now so I can't seem to link back to the pictures again. There is a link in my first post. Hopefully it will be back up soon. I suppose after the fact is too late to have you take a look at it...

Thanks for the tip.

 

I have had it running for a few days now. Been working it pretty hard actually. I have noticed that it is a whole lot quieter again. It also builds pressure considerably faster again. So I am happy with it for now.... well maybe not happy but satisfied that I have something that will produce compressed air, at least for a while...

My last compressor was a campbell housfield cast iron 6 horse. It was a decent compressor for the bux. That one spun a rod and dropped a couple valves. The rod was my own fault, who knew you had to check oil in it more than once every five years.... I rebuilt that one and passed it on to my dad 5 or 6 years ago, he is still running it.
