There are a couple of things to look for on the air compressor.

You will need to see if the piston ring is damaged or if you have a broken reed on the valve plate.

 

These are typically the two most common problems with this model.

If you have no leaks the first thing I'd check is the ring and cylinder for wear. The cylinder wear is usually pretty obvious, but if you can see light around the piston ring it's bad. The replacement part number is N038785. Also check to make sure no valves on the valve plate part number A09819 are broken or bent.

SOURCE: I have a DeWalt D55168 type 3 air compressor that the motor brushes keep sparking and smoking.

If the compressor is relatively new and performs well, it is probably not an issue. Brushes always spark on the commutator but without seeing the extent of the sparks it is hard to tell for certain if it is "too much" or not. I wouldn't expect any significant smoke from the brushes and commutator or the armature unless it is brand new and the oils from manufacturing are being burned off. If it is a very old machine, it is possible the armature is shorted out and needs to be replaced.

If, on the other hand, it is not brand new, but a couple years old, has had use, but not heavy and continuous and you just see small sparks coming from the brushes, then it is probably ok. If the sparks seem larger than what you are accustomed to and you are seeing smoke coming from the motor at all (presuming it is not the brand new situation noted above) then the armature may be starting to short out and/or the windings in the motor may be starting to burn out. Electric motors that are used within their design constraints (not overloaded, not run on low voltage, not run continuously if not designed for that use, not overheated) do not tend to burn out. However, if the windings get covered with sawdust (which insulates them), you run the compressor continuously for hours on end, day after day, especially in a hot environment and/or with low voltage, then you have probably overheated the windings and the motor is burning out. For a compressor of this size and quality, it would likely cost more to have the motor rewound than it cost to replace the compressor. Also, if it has failed from overly hard use, rewinding the motor will not prevent another burn-out, you need a larger, more durable compressor.

I HAVE A BRAND NEW DEWALT D55168...I'VE HAD IT ABOUT 3 MO.S... I WAS USING IT INSIDE ABOUT 2 MO.S AGO AND IT SIMPLY STOPPED... I HAVEN'T HAD TIME TO DEAL WITH IT, AND I DIDN'T FILL OUT WARRANTY...


If you bought it at HD return it for a new one. If not you will need to use a meter and check power from receptacle to on/off switch to pressure switch., Check motor winding. If all else fails call Dewalt and they will help you.dfffd6xqamff+a17gofmrmxewaaaaaelftksuqmccaa==

Dewalt D55168 air compressor runs until 95 psi and never stops. Pressure never goes above 95 psi. It use to stop around 140 psi.


Check for leaks all over the machine. Possibly the O ring on the drain valve is damaged. If the machine is oil-less, the big rubber O ring on the piston could be worn away.
When the machine is turned off can you hear air leaking from anywhere?

Sounds like a loud leaf blower, no engine sound.


You can get a rebuild kit from DeWalt for about $40 and fix it yourself. The flappers are most likely bent.

D55168 lost compression while running


The dewalt model d55168 is a high-end oil-free compressor. Oil free compressors could have a short life span due to dusty or dirty conditions at the job site. The cylinder of your compressor is open from the bottom and will **** in debris scratching the cylinder/ silicone-vinyl piston ring reducing pressure. However the reduction in pressure will be over time till the point that the compressor will not reach cut-out pressure and just keep running. If you lost pressure suddenly to "0" then you probably lost the drive belt. A replacement can be found at a local dewalt service center or ordered thru www.toolpartsdirect.com. When you take down the compressor, be sure to examine the cylinder /piston for wear. These are the two most common problems. Good Luck on your repair and email if you have other questions.
