Discussion is closed. To ask our experts a question about a part, use the Q&A feature on our product pages.
Question: Flywheel

Gene1152

Pressure was not building on my dewalt compressor. Thought belt was issue. It was but so was the broken bolt that holds flywheel on. How do I get bolt out? Both from the piston arm and in the motor
Hi Gene1152 Is there any way to drill them out, or get an EZ OUT on them? Unfortunately, flywheel bolts are usually torqued in very tight.
Question: Belt For Dewalt Air Compressor

1724407

I replaced the valve plate, and the compressor runs but doesnt build pressure and it doesnt turn off.
WJA
Hello 1724407 ,

Your piston ring and cylinder may be worn to the point, that the air cannot be compressed. You can repair this problem by using the part number N038785 Conn Rod/Piston Assy.

-WJA
Question: Motor Throwing Sparks

578342

It appear that the motor bearings are worn to a point that the shaft has enough movement that causes the brushes to throw sparks. Are the motor bearings replaceable? Also, is the drive pulley on the motor just pressed on and can be removed with a gear puller?
WJA
Hello 578342,

The manufacture doesn't have a parts diagram for the N099921SV Pump Assembly. I have never had anyone ask me if you can replace the bearings in this unit. If you are mechanically inclined and feel comfortable attempting this, go for it. You will have to obtain the bearings from a bearing supplier. The part number N001137 Motor Pulley is pressed on to the motor shaft. The manufacture says to press to .094 inch from end of shaft. A gear puller should be able to do the job. If you want to replace the Brushes, the part number is A10157SV Carbon Brush Set.

-WJA
Question: DeWALT D55146 Air Compressor

1367084

My air compressor is not holding air. It continues to attempt to add air but it seems like the regulator is not holding the pressure. Do you recommend the following kit to rebuild the regulator or do you think it is something else.
N008792 Regulator Repair Kit
WJA
Hello 1367084,

It could be that your Piston And Cylinder are worn and the air is leaking back thru these parts. In that case you would need part number N038785 Conn Rod/Piston Assembly . Or it could be the A09819SV Valve Plate Assembly. In either case you will need to inspect them for damage or wear.

-WJA
Question: Pressure Switch

bbrucelf

compressor won't turn off. As pressure builds Air starts leaking out of the face of the outlet regulator valve. Would the problem be the pressure switch? Is there any adjustments or cleaning to be made on the regulator switch before replacing it
Hi bbrucelf,
It sounds like you have a problem with the pressure regulator on the compressor.Air leaking out of the face or around the adjustment knob of the regulator is an indication that the regulator valve pin is frozen or sticking. Some of the regulators will have a cap screw on the back that can be removed and the valve pin remove.The cap screw has a sleeve attached to the back of it that the valve pin and a small o-ring slide in and out of .Clean this and put a small dab of grease on the o-ring and make sure it slides in and out of the sleeve freely.This should fix the problem.If not replace the regulator.Hope this helps.Good luck.

Question: Fan On Dewalt D55146 Type 2

1184980

The blades on my fan have broken off, I am ordering a new fan, how does this attach? and what would cause the blades to shatter?
Hi,
If I remember right the fan is pressed on to a spline link removed regards to the fan breaking,I didn't see any service bulletins about a problem with the fans but the small plastic fans on motors are under very high centrifugal stress loads and it could be that one broke off and hit the other causing catastrophic failure of the cooling fan.Hope this helps.Good luck.
Question: Motor Cutting In And Out Randoml...

Parker

I've had mine for a few years and it just started randomly cutting on and off. At first I thought it might be that the safety regulator was messed up. Not the problem... It was the black (hot) wire going up into the motor. There was some little temperature breaker wired in to the black wire, zip tied to the coil in some clear plastic shrink wrap. I guess it went bad so I cut it out and just bypassed it (wiring the black straight through without the sensor). It's been running fine ever since. The only problem I ran into was that there was a little more slack in the wire and the spinning part of the motor ended up pulling it in and severing it so I re-did it and tucked it away from the moving parts and boom,, just like new! I'm sharing this bc I was 10min from buying a new one before I discovered the fix. Don't want anyone else doing the same.
WJA
Hello Parker,

Thank you for providing this valuable information. I hope that it will be well read by those that are having the problem with their compressor as you did.

-WJA
Thanks a Million for this information Parker, I'm including a link with a picture of it to help anyone else, the motor wire is real short and had a hard time crimping a terminal to it, No where else is there a mention of this problem that would drive you crazy. Thanks again Parker.

Question: Compressor Do Not Built Pressure

Question: Compressor D155146

henryg11

My compressor stays on and do not built pressure. what parts do I need to replace
Hi henryg11,
You first need to disassemble the pump and look for damage on the reed valves or cylinder walls.If you have any damage then you should replace both cylinder /rod kit and reed valve assembly.Hope that helps.Good luck.

Question: Dewalt D55146 Type 2 Compressor

toolmanou812

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.

Hi toolmanou812,
Does it shut off at higher then normal pressure or not shut off at all blowing the safety valve?
Tinker
Question: Dewalt D55146 Type 1 Check Valve

g8rgrad98

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"?
Or is there a part I'm missing?

Hello g8rgrad98,

I am thinking you might need part number SSP-491.

Hope this helps,

Question: Conn Rod Piston Assy

tommypa8

why cant I just get the o ring that is all I need the rest is fine
WJA
Hello tommypa8,

If you are looking for the o-rings the part numbers are as follows, A03856 and ACG-45. If it is the piston ring you are looking for you will have to order part number N038785.

Hope this helps,

In answer to your question regarding the SSP-7812 nut and sleeve assembly. Yes the sleeve is included with this part.

-WJA
Question: Check Valve

Chuck

Does the new Dewalt compressor tank check valve come with the outlet nut or is that another part?
My new valve came with the outlet nut in place.
WJA....if you see this thread, will you please see what you guys can do about the spamming jackwagon that keeps posting on here. He has posted MORE than the 3 count he is given. His post is just above mine. THANK YOU!
Question: Pressure Regulator

drew

I am in need of a replacement pressure regulator. Can you help me find one?
No, I can't find one either. It looks like we need to buy the complete manifold, now that SUCKS.
Fix the old one. Pull it a part and clean it and oil it. It may work as new.
They sell a regulator repair kit if you want that. I'm going to take mine apart and oil it up to see if that helps. I think the regulators pretty much suck on these.
I had the same problem so I used one out of an old porter cable compressor I had sitting around. I came to find out it was the exact same regulator and fixed my problem. You also may be able to just take yours apart and clean it well. It stopped mine from leaking but the bolt was stripped so I had to use the porter cable one.
WJA
If your regulator is damaged or broken you will have to purchase the complete manifold or try finding a used one. But if it is leaking or dirty and needs service, the least expensive would be to purchase a regulator service kit, part number N008792. Cheap and easy fix.

Hope that helps,
WJA
Question: Help With Dewalt D5514 Type 1 Be...

jamesfiguracion

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.
Mike
Hey James. You're right, the belt installs with the letters facing out. It's nice too because you won't have to remember the part number. ;) Belts break for all kinds of reasons. Over time, of course, any belt will break but I don't suspect your manual operation of the compressor made any difference.
Hello! I am following the forum for two months and now recently joined the forum because it seems me interesting * informative.

SERVICE BULLETIN PAGE 1 OF 1

ISSUED: January 14, 2009
Written By: K. Butler
SUBJECT: PROPER BELT TENSIONING
UNITS: D55146, D55146-CA, D55167, D55168 & D55168-CA COMPRESSORS
DATE CODES AFFECTED: ALL


Proper belt tension is critical to ensure maximum belt life. An inexpensive belt tension gauge called the Krikit (model KR I) is available at local auto parts stores and some large chains. This gauge will now be available through Fidelitone as 233804-43. The guage will work for belts up to 7/8” wide and has a 30-150 pound range.

Follow the steps below to tension the belt:

a) Using a 3/8” wrench, loosen screw on idler assembly. This will release tension from the old belt.
b) Remove connecting rod bolt and move connecting rod from bearing support while leaving piston portion in cylinder.
c) Remove old belt and replace with new belt. If using A12210 belt, place lettering on the belt against the flywheel (large diameter pulley). If using N011005 belt, place lettering away from flywheel (belt teeth against flywheel).
d) Replace connecting rod and bolt. Tighten bolt to 100-120 FT-LBS.
e) Tighten the idler screw to about 40 IN-LBS. There should be enough friction to hold the idler in place while tensioning.
f) Using a 5/8” wrench, rotate the idler assembly clockwise to tension the belt; then, rotate the flywheel a few times to equalize the tension. The tension gauge should read between 60-80 LBS when checked on the longest belt span. To lock the idler assembly in place, tighten screw to 84-120 IN-LBS. Recheck tension and adjust as needed.
