Have owned this compressor for several years without a problem until the last time I used it. The compressor will not turn off at the desired pressure. Once guy tells me it is the regulator and another says it is the pressure swith. I think it is the pressure switch. Any help woulb be greatly appreciated.

Hello, I purchased the replacement Check Valve A19170 from you all, which threads at 1" into the tank. The tank on my compressor is 3/4". Do you sell a check valve that is 3/4"?

why cant I just get the o ring that is all I need the rest is fine

My compressor will not build air pressure. Will this kit fix the problem?

Does this come with the sleeve?

does this compressor use oil? and have a breaker and what makes this compressor get hot and pop the breaker even if is connected to power pole?

The regulator knob leaks air under the cap, and clicks when turning higher or lower air out put. Also, it's hard to turn in either direction. I don't need the whole manifold, just the knob, the manifold parts, not available. D55146 type 1

When I plug in my D55146 and turn the switch to auto, the unit shows no signs of power. Does anyone have any idea what the problem could be?

Thanks

Does the new Dewalt compressor tank check valve come with the outlet nut or is that another part?

Is the connecting rod bolt to the belt pulley left or right hand thread?

I need a regulator for my Dewalt air compressor model #d55146. Do I need to purchase an entire manifold assembly ?

My pressure stays at 60lbs. What could be the cause?

I am in need of a pressure regulator! The one I have keeps bleeding off air pressure. I don't see one on the parts list?

My pressure stays at 30 lbs and will not increase. Could it be my pressure that is faulty?

I am in need of a replacement pressure regulator. Can you help me find one?

I have a DeWalt D55141 air compressor that fills the tank to 175psi and then the 175 psi relief valve opens and then purges the tank pressure. The tank never reaches over 175 psi and the motor never shuts off when it reaches 175 psi. It just pumps to 175psi and then purges the tank and then starts the cycle all over again. Other than that, the compressor does well. Does anyone know what is going on here or what part I may have to replace? I tried replacing the relief valve thinking it may have been weak but same problem still exists. Please help.

The first question is: which side of the belt faces in or out? The shiny side or the rougher side? My intuition tells me the not so shiny side since it presumably has more grip and the fan labeling is on the shiny side which would most like wear out and make it unreadable if an old one had to be replaced. Also, on a car's v-belt the ridges face inwards obviously to match the ridges on the pulley and I don't remember reading any fan labeling printed on those ridges. Was that a long-winded enough introduction?:D

Second, did I need to purchase part number 233804-43 TENSION SCALE (BELT TENSION TESTER). I stumbled upon this part/accessory(?) on the Dewalt Service Net site (link removed ServiceNET - Official Online Store for DeWALT, Porter Cable, Delta, and Black and Decker Parts).

Third, I haven't had this compressor for more than a year, is the belt breaking in half a common occurrence? When it broke, I was shutting it on and off manually because I was using HVLP paint sprayer and I didn't have another pressure regulator installed. Could this have been the reason? I admit it was a pretty numbnut-amateur thing to do...the kind of thing your dad would yell at you for when you were a kid.:D

Thank you in advance for any help.

This compressor was great at first. preasured up fast and kept up exceptionaly well. But it has been a constant source of trouble sence about nine months after I purchased it.
