[Shop-talk] Air Compressor threw a rod

[alfuller194 at gmail.com]

Yes. The piston has a simple ring that seals the cylinder and keeps the piston off the cylinder wall. After a while they do get scuffed up, and the fix is to replace the cylinder and seal. If you catch it before the kind of catastrophic damage I have, you just pull the head, unbolt the connecting rod, remove the piston/connecting rod assembly along with the cylinder – and replace them with new parts.

 

I think I can find all the parts except the connecting rod… following is a diagram. #58 is the cylinder. It just drops down into the body.

So, do these oil-less compressors have a piston sliding in a cylinder?  (That's what it looks like in the photo).  How do they manage without lubrication?

So I bought a Sears Craftsman 6.5 HP 2-cylinder oil-less air compressor used. Since I bought it used, I don’t know how old it is, or how it was used… Recently I fired it up and it began making a noise, so I shut it down, and found lots of plastic parts on the shop floor. Upon inspection, it has thrown a rod on one cylinder. The plastic parts were from the fan.  The issue is finding a connecting rod and cylinder kit for it, since it appears to no longer be made/sold, and sears parts direct doesn’t have the parts.

 

The Sears Craftsman model # is 919-165600, and it looks like it was also sold as a DeVilblis 919-16560, as well as lots of other makes and models.  The connecting rod is an ACG-1.

 

Some people claim there are only about 3-4 different cylinder configurations, so I guess my question is what would be a good source for locating parts for this thing? I’ve looked around Amazon, E-Bay, etc. and so far have found one kit, but its $139 for a single cylinder! See https://www.amazon.com/Benron-Equipment-Replacment-for-KK-4835/dp/B0814GP4ZH/ref=psdc_9022420011_t3_B00F9Z4A1G. there must be a better alternative.
