Thanks! The leak comes from the top of the fitting around the tube. I tightened it up, but the leak is still there only slower. It resembles a compression fitting somewhat.
If you ya e to bang the motor I would check the brushes and make sure they are making good contact. There are two coiled metal springs that apply tension to the brushes which makes contact with the rotor on the pump. The metal slide where the brushes air in has a little tab to push in and you can pull it out of the armature .
I have a Dewalt 55146 compressor and have been having a problem with it shutting off when it reached 225 lbs. It is supposed to be 185 lbs turn on and 225 lbs turn off. I ORDERED AND INSTALLED THE CORRECT PRESSURE SWITCH AND IT GOES TO 250 AND DOES NOT SHUT OFF. I doesn't seem to go above 250 BUT it just does not shut off. At first I thought it was a factory default pressure switch, got another one today and it is still the same thing. Questions, Is it something else that makes it not shut off at 225 as it is supposed to do?? It goes to 250 so far, but does not seem to go any higher. Is this dangerous?? No leaks or any thing. Basically I AM THINKING TO JUST PLUG IT IN WHILE I NEED IT AND UNPLUG IT WHEN I AMF FINISHED. What the heck is going on here??? What to do. Thanks Joe
A shot of some carb cleaner spray would have made the reed valves look and work like new. I am surprised you didn't clean anything up while it was disassembled.
I ordered an '0650 off of Amazon for a Craftsman 30 gallon compressor the o-ring seal only lasted about three or four fill ups before it went again I don't know what went wrong the motor is fine the baron is not loose the one thing I did notice about the parts the cylinder sleeve that came with the new parts was made out of iron or steel or zinc the original sleeve was made out of aluminum I don't know what made the seal fail that quickly I did not put any oil on anyting any comments on why this happened greatly appreciated when I took it back apart there was lots of dust inside
I've had the same issue with my craftsman abt 8 yrs ago. Poor replacement parts maybe, I did buy factory replacement parts, cylinder and piston/ring kit. I still have it, may try again, any luck with yours?
It was the piston arm rubbing on the flywheel. There was enough friction to prevent the motor from coming up to speed. Once the new piston was installed and aligned properly, it starts up ok now.
i think the brushes on the motor are nearing end of life and not making good contact with the rotor. The motor shouldn't be arcing like that while it is running. Thats why its not running as strong and starts and stops when you tap it
kayzrx8 I would check the springs that Retain the brushes . Not causing enough tension to hold the brushes right to the rotor causing the arcing. Also not plug it into a 16 guage extension cord and rather directly into wall outlet 20 amp. Or at least 12 guage extension cord
If I recall correctly, I thought about that. But the seal is designed into the end of the piston in such a way as to not be replaceable by mortal men such as I. :-) Thanks for watching!
muchas gracias sr Lumber, tengo el mismo problema que solucionó en tu compresor voy a cambiar el pistón completo como lo hizo usted, quiero agregar que lo compré en una subasta lo traje a casa lo encendí duro 15 minutos trabajando cuando escuche un ruido y fue que reventó la biela, pero como veo en su vídeo eso pudo ser por desgaste en los sellos quedó con mucha luz y lo reventó la vibración, me dice por favor cual es la referencia del pistón, las escobillas o carbones y la correa dentada para hacerle un mantenimiento general y donde lo puedo conseguir, que lo uso muy seguido para mi trabajo como contratista. Mi nombre es Omar González Rivera soy de envigado Antioquia, Colombia, mi correo es multiogr@une.net.co por si me puede ayudar con las referencias y su posible valor, por acá lo que le pueda colaborar con mucho gusto, muchas gracias, soy un admirador de la tecnología americana. Por favor cuidese mucho usted y su familia hasta que salgamos todos de esta pandemia.
Omar, compré las piezas en un centro de servicio de DeWalt. Este es el sitio web. www.toolservicenet.com/ El costo fue de aproximadamente $ 46 US, más el envío.

Good video, but I feel compelled to offer a word of caution. Regardless of how well the compressor itself works, the tanks have a limited lifespan. Even in well maintained machines that are drained everyday, that is typically about 10 years (less if it is not properly drained). The repetitive cycles of build up and release of pressure lead to metal fatigue over time, usually at the welds. Many explosions, some leading to serious injuries or death, not to mention loss of property, have happened because of old air compressor tanks. Since you bought it at an auction, you probably don't know the age of this tank. Judging by how worn out the compressor was initially, it may well be 10 years old or more. Be mindful of that and be safe.
How many air tank explosions have you witnessed? I been around alot of old old old antique compressors thats been through more heat cycles than days most human beings have been alive never seen a explosion
@@dreece2000 I agree with both of you. It does make me nervous, especially since I vary rarely drain the condensation from the tank, but I've never seen or heard of them failing, and hopefully never will.
@@dreece2000 That's because of modern safety standards but it never hurts to look inside pressure vessels during periodic maintenance. Tanks not failing often doesn't mean it doesn't happen and consumer crap compressors don't always have thick tank walls (though the DeWalt portable with the same pump I just cut up to make a welding cylinder cart is decently stout, about 3mm).
Great video. I just needed the piston ring replaced, before my compressor would only go up to 50psi after 10 minutes now it's 225psi
Well done, Z. Get some teflon tape to seal your fittings. check the torque on the pump head bolts.
Thanks! The leak comes from the top of the fitting around the tube. I tightened it up, but the leak is still there only slower. It resembles a compression fitting somewhat.

What to do.

could you show the part# 's and if you could where did you get it? pleae
LOVE the t-shirt !
Thanks!

Thanks for the tip! I need to change the belt and brushes soon. I'll give this a shot.

Thank you
I just did this same repair, how is this holding up? The replacement parts don't seem to be the same quality, namely the arm .
18 months later and it's still going strong. I do need to replace the belt and brushes though.
Where can we buy this parts?
I bought the parts from a DeWalt service center.

did you fix the problem with it not firing back up?
bad unloader valve ?

I'd hit the commutator with the Cratex rubber abrasive I keep handy too.
Size of the bolt looks like 7/8
Think I need the same thing, compressor runs and runs to get up to Max air 200 PSI. Edit and the belt looks like it's going to launch any day 😂
They’re called reed valves
You just need the rubber seal on the piston.
If I recall correctly, I thought about that. But the seal is designed into the end of the piston in such a way as to not be replaceable by mortal men such as I. :-) Thanks for watching!
Error el problema eran los carbones. Votaste la plata
