Question about Dewalt Air Tools & Compressors

1 Answer

I have a D55155 compressor. When completely empty of air the guages do not read zero, should they or does it take awhile for them to go down. Also where is the pressure switch on the D55155?

It seems to run often, but I think the disconnect couplers are worn. What is the parts number for them. I forgot to add that when using the regulator nothing changes on the guage.

GUAGES: Guages read exactly what pressure is on them at the time, there is no bleed down time. If the reading is off at zero it will be off accross the dial. The case may have been hit to knock the guage out of allignment or the needle is bent but that's hard to do unless the plastic cover is broke off.
PRESSURE SWITCH: The pressure switch is the black box under the large pannel right behind the quick connects.
LEAKS: Leaks cause compressors to cycle on and off frequently. They are easily found with soapy water in a spray bottle. The guages and quick connects should be replaceable with off the shelf (Home Depot, Lowes, tool repair shops) similar parts.
REGULATOR: If adjusting the regulator does not affect the pressure at the quick connects, and on the guage, it may be stuck or broken. This could also be the place to look for a leak. Dewalt does make a regulator repair kit, part number 5130027-00.

Parts for coleman are available at www.mastertoolrepair.com your compressor is listed as L0502710. If however you like to tinker, you can make a pretty good reed valve out of aluminum can material or other (any ideas?). It is fairly easy to cut, does not last as long as factory stainless steel, but for short term, why not? Good Luck

SOURCE: dewalt D55155 air compressor regulator installation

The d55155 unit suffers from regulator problems due to weakness in the design of the manifold. The manifold parts are very light duty metal and will break during installation if not carefull. If you can return the parts to dewalt it may be more efficient to to use a generic pressure regulator from www.grainger.com for about 20 bucks and mount using a couple of 1/4" tees directly off the pressure switch. Remove the hose from the pressure switch that feeds air to the manafold . Install parts so that the quick disconnects, guages and new regulator are accessable from the side. It will not be pretty but problem will be solved for long term. We repair other brands that come with control panels using the same method. Pressure regulators built into a manafold will fail. For demanding customers we have recreated the manafold using 1/4 pipe fittings and refit the gauges and grainger regulator into panel.(lots of work) But leave the safety unloader at the pressure switch. If all you need is a good functioning compressor same time and money and mount to side. Good Luck and email if you have questions or other issues with your dewalt.

SOURCE: I have a 3hp 15gal air compressor that i bought

I am assuming that your compressor is oilfree type. Lets go over some basics to determine where fault is located. You will need to do some simple tests. If there are leaks the compressor may not reach set pressure. I use soapy water on all connections and on the head/headvalve (remove plastic covers to get to all parts that may leak) while compressor is running. Make repairs as necessary. If still low pressure, while compressor is running and has reached max obtainable pressure (in your case 15 lbs), carefully place finger over intake port hole (remove filter). If the compressor is pumping normally but leaking there will be ample suction at intake and cause the compressor to speed-up when intake is obstructed with finger. If you feel plenty of suction and no visible (soapy water) leaks, then the problem is probably the cylinder /ring is not correctly seating /scratched and air is leaking past cylinder. Make sure that the cylinder /piston ring is properly aligned and that the lip on the vinyl ring is up toward the head. On oilfree compressors you can examine the cylinder by pushing the piston all the way up, then look for scratches neer top of cylinder. If scratched install cylinder kit. If you do not feel suction but rather air blowing out of the intake, then the problem is the headvalve plate/reed valves are leaking. The reeds must seal perfectly on their seats and not be bent or have obstruction. Replace as necessary. Only one other thing to check and that is the intank check valve. Easy to check. Run compressor till you have about 15 + lbs in the tank then unplug compressor. Carefully loosen the inlet hose at checkvalve and listen for air leaking out of tank. If leaking replace checkvalve. Use caution when removing head to try and save the gaskets. If you see any model numbers on your compressor beginning with WL, you probably have a unit built by Campbell Hausfeld and can find parts at www.chpower.com
Good luck on your repair and email if you have other question.

I want to know where the oil goes on this machine?


ON a d55155 compressor, you will find the dipstick on the left side as you are facing the control panel. Notice a small black knob on the end-bell of the pump. Pull out the dipstick and notice the oil level line just up from the tip of the stick. Over-filling will cause oil to leak. Use 30wt non-detergent oil or compressor oil. Good luck

Dewalt d55155 compressor runs to 60 lbs then acts like not enough power and shuts down


Looks like it's an oiled style compressor. Is it getting pretty hot by the time it hits 60psi? Might be low on oil, or the oil has been contaminated with water from condensation. If that's the case then what is happening is the compressor is causing too much resistance for the motor to turn it because of the excess friction. This is could be what is causing it to shut down prematurely.

I have d55155 and cant get over 60 psi, it never shuts off. how do i tell where the leak, o ring, or teflon tape should go. should the release valve be in a certain position? it seems down all the way


Could be leak or faulty valve plate in head. Use soapy water and spray all fittings including drain valve and pressure regulator. Repair as needed. If no leak found suspect problem with compressor. Try simple test, with compressor running and has reached max pressure (60psi) remove air filter and feel intake for suction. Be carefull could be hot. The suction should fairly strong. If no suction or actually feels like air is blowing out of intake, suspect valve plate. Parts are available at dewalt service center or www.toolpartsdirect.com. Good luck

Kenmore23022 won't spin...and is making a loud buzzing noise. Water drained fine but aggitator seems stuck or something


This assumes that you have a basic Kenmore / Whirlpool top load, direct drive, neutral drain (it doesn't spin until the pump removes most of the water) machine.

First, see the Sears parts site for your washer: (The 23022 number is a stock number, not the model number)

http://www.searspartsdirect.com/partsdirect/index.action

Enter your model number (###.######) and you'll see a list of major sub-components with diagrams and parts.

Look in the section for the motor, pump gearcase and you'll see the Motor Coupler.

Kenmore / Whirlpool top load, direct drive washers use a "Motor Coupler" between the motor and transmission.

It's used as a fail safe device and consists of three parts.

Two of the parts are the same, plastic units with three prongs that fit on one of the motor output shafts and the other on the transmission input shaft. Between them is a rubber piece with six holes.

The power from the motor is transmitted through the rubber piece to the transmission.

The other shaft on the motor directly drives the pump. This is likely why the machine drains.

If the motor coupler is broken, or worn, the motor may not be able to send full power to the transmission for agitating or spinning.

See the following for how to remove the cabinet, pump, motor and motor mounting plate to inspect and replace the motor coupler.

http://www.american-appliance.com/catalog/newsdesk_info.php?newsPath=16&newsdesk_id=137

If the coupler looks damaged, it's a relatively easy fix.

Pry the plastic pieces from the motor and transmission. Some people use a claw hammer but I've found that using a small (6 inch) pry bar works well.

Carefully fit the plastic pieces over the motor and transmission shafts and press them in place (Use a 1/2" of larger socket to put pressure equally around the pieces.

Put the rubber piece on the transmission plastic piece.

Replace the motor mounting plate.

Carefully line up the plastic prongs on the motor based plastic piece to the three un-used holes in the rubber piece. If they don't line up right, the coupler could be damaged.

Mount the motor, don't forget the two screws, put the pump back on the motor and use its' clips.

Put the cabinet back on, don't forget to plug the lid switch back in and re-mount the console.
