Question about Craftsman Air Tools & Compressors

1 Answer

I have a Devilbiss Air Compressor that the Pump has started leaking oil badly. There is a lot of end play in the crankshaft. This compressor is 22 years old. Should I buy a new pump or a new compressor? The scfm on this compressor is great where the new compressors are much less scfm and hp. Mine is a 5hp, 20 gallon tank.

    Thanks for your reply. What about the excessive play in the crankshaft? I can pull on the pulley back and forth and the crankshaft moves quite a bit. If this was a car, it would not be rebuildable due to the end play. I do not know what the specs are for the end play on this pump or if it is supposed to move that much.

    End play is not as critical as up and down. If the up and down is minimal,try a new seal.
    The worst scenario is a few bucks for a seal and a little time. Good luck

    I am just concerned that after 22 years of use, the crank seal may not be the only thing needing replaced. I do not want to waste time and money if the end result is not going to be a properly functioning compressor. If I need to buy a new one after messing around with this one, you know what I mean?

    I have had my compressor for over 25 years. I have maintained it properly for all those years.
    I have a 5 hp 120 lb 50 gallon tank. If you are finacially able buy a new one and leave me alone. stew

Devilbiss air compressor Running hot and low pressure

Sounds to me like you have an air leak somewhere. When the compressor motor runs for too long a time, it's 'gonna get hot! Disconnect the fittings one at a time and use Teflon tape at each air connection. Check for leaks using a soap and water solution at each fitting.

1988 20 gallon 5hp sears air compressor leaking quite a bit of oil. Can it and is it worth repairing?

I would think that is is actually coming from the crankshaft seal and running down. Does it leak when you are not using it, or just when it is being used? If it leaks even when it is not being used then it could be the drain plug. If it only leaks when being used then I would look at the crankshaft seal. And yes it would be very feasable to repair it, because like all things they don't make them like they used to.

Crankshaft pulley r/r

Place the crankshaft pulley bolt removal tool over the end of the crankshaft bolt. Tool will hold the pulley in place while you apply torque to the bolt with an impact wrench. Start the air compressor by plugging it in and turn it on. Set the pressure of the compressor on the highest setting. Attach air hose on the air compressor to the air inlet and the locking mechanism using the quick-connect lock on the end of the air compressor hose. Set the impact wrench to turn counterclockwise. Spray the crankshaft bolt with penetrating oil. Make sure you soak the bolt head in oil so that it is easier for the wrench to remove. Secure the socket end of the wrench to the pulley bolt and pull the trigger on the impact wrench. You might need to reapply penetrating oil several times during this process to loosen the bolt up. Eventually, the bolt will come off 215 lbs torque, and simply stated righty tighty, lefty loosy. Hope this will assist you.

The unit only blows warm air. it just stopped kicking on the condenser/compressor to make that radiator cold and blow cold air. any help?

The compressor is not starting either because:
1. The compressor has gone bad
2. The system is low or out of refridgerant. There may be a slow leak, when there is no refridgerant in the system the compressor will not start.

Re-charge the system with appropriate refridgerant, if the system has a charge already or holds a charge when you charge it then the compressor should start.
If not the compressor could be bad, sometimes you can get a hard start kit instead of replacing compressor. If the system does not hold a charge then you have to find and repair the leak before anything else...

Good luck. Please give good rating, it meens a lot to me....Feel free to contact me again...
