SOURCE: Air Compressor

Dewalt recommends synthetic oil in their compressors. The dewlat part # 5130427-00 quart, and 5130702-00 for a 4oz size. Available at www.dewalt.com or their service center. I have been using the Lowes brand of synthetic compressor oil. Kobalt oil sells for about $7 and works great. If you do not use your compressor all day like I do, you can use the standard grade of Kobalt compressor oil that sells for around $3. Synthetic oil is for extreme conditions. Good Luck!

Hey there. I am having problems with my Emglo Dewalt d55151 compressor. I have taken it apart and and cleaned everything up. The reason I did all this was..because the cold start valve stays open and its...


The cold start valve will close when volume of air from compressor is sufficient to overcome spring under pin (allows the motor to come up to speed). Evidently your compressor is producing very little air. Usually the problem is leaking or broken reed valves or gaskets. Remove the head and look for torn/ leaking gaskets and replace as needed. Examing the reed valves and seats and look for broken cracked reeds or worn seats. Some of the valve plates used in Dewalt compressors are made of aluminum and would fail. Parts are available at www.toolpartsdirect.com or local dewalt service center. Good luck with your repair.

If you have oil coming out of the oil fill and dip stick you most likely installed the reed plate upside down. Usually it says this side up or there is an arrow pointing up on the reed plate.
This is a good sketch of compressor and reed valve assy.

Usually the reeds are on top of the plate facing downward. If you have just a reed disc.. then the disc will need to be inverted.

Thanks for Choosing FixYa.

Tank wont fill with air but compressor runs


Can you hear the air coming out? Or it is not pumping up at all? If the air is not coming out somewhere like the bypass or the regulator, or the drain plugs, then the reeds are shot in the head, it is an easy fix, and an easy part to get, I hope, call Dewalt's hotline and tell them what's happening, they will fix you up.

Dewalt compressor not filling with air drained tank closed valve


Some dewalt air compressors with single cylinder are known to develop trouble with reed valves and /or failed gaskets in head. Parts lists and parts are available at WWW.toolpartsdirect.com Simple test is to remove air filter and check for suction at intake. Bad reeds will tend to blow air out intake as pressure increases. Failed gaskets in head will cause very high temp at discharge hose. Parts are not too expensive. Enjoy

Dewalt compressor not filling with air


if you do not have any air leaks and it is a oil less compressor than it is most likely the piston seal is wore out. if it is an oil compressor that it is likely a flapper valve
