Your A/C unit should be hermetically sealed and there should be no oil coming out. If there is a leak in your unit then the first thing you will notice is a hissing sound followed be a foam of oil coming out where that leak may be. The solution is to first find the leak and seal it, usually be soldering it with high temperture solder (Silver/Bronze) with a tourch that will go to at least 1000 degrees. Once it is sealed you will need to go to the production line coming ont of the compressor and open it up, usually be breaking it and then soldering on a copper line and then attaching a valve to the end of it. Once this is done you will need to have a vaccuum pump connected to the production line and draw a vaccuum as close to 30 degrees down. Once this is done you must let it sit for at least a half hour to make sure everything holds at the vaccuum level. If this works then you need to fill the unit with the appropert refridgerant and cappella oil if necessary and pinch off the production line and braze the end. Check for leaks and if none then your good to go.
Good luck,
Marty

How to install a 2008 chevrolet uplander van a/c compressor kit

Michael, this job requires special tools. You need to recover the refrigerant. But your big issue will be removing all of the moisture from the system, after the compressor surgery.
System oil is another major concern. As per directions, measure that you remove from the compressor. Adjust accordingly. Meaning for example, (Random values, check specs for your system) if you were to have 4 oz of oil in the compressor, but you find only 3 oz (measured!), you are not down 1 oz. The entire system is 25% low on oil. Adjust accordingly. No biggie, but if you are not aware of these things, you will introduce moisture into your system, which will react negatively with the metal parts of the system, causing costly damage.
Always replace the receiver/dryer when you open an A/C system.
(it has oil in it, too...)
Really, dollars and cents, this job might want to be done by a trained professional.

Discharge of refrigerant is ******* most everywhere.

HDC 2HP 5 Gal Pancake Air Compressor - replaced pressure switch - now takes long time to pump tire - motor runs long time - slow recovery - actually overheated and melted off the plastic part on muffler....

Barb:
Your compressor takes standard 30 weight compressor oil or 30 weight motor oil... you need to put in the correct amount. The slow recovery is due to a leak somewhere. after adding the proper amount of oil, run the compressor and use a soapy solution to check for leaks. Check especially the tube that runs from the compressor head to the tank, and also check the air connection at the pressure switch. When you find the leak, you can disconnect the connection and use Teflon tape on the male end connector.

AC compressor locked up and broke belt

That happens when the system leaks,not just refrigerant
but the refrigerant oil with it.

The clutch can be another problem.

Now you need to determine if the clutch is the only problem

If you seized a compressor, you have trash throughout the
entire system & at todays prices & a 1996 vehicle, I wouldn't
fix that.

The clutch or compressor alone you could have done,
but not if it burnt up & sent debris everywhere.

Air compressor will not start.

When you are texturing walls you need a texture machine, they work very differently from an air compressor. An air compressor, especially one as small as the Central Pneumatic 40400 cannot supply the constant flow of air required by texture guns. If your compressor was running long enough to get hot enough to smell it then stopped working some of the possibilities are:
- Popped a circuit breaker, either the house breaker for the outlet you were using or the breaker on the compressor motor. This usually occurs because the compressor is being run on a too small guage or too long extension cord or run constantly for an extended period.
- Motor got overheated and seized up or shorted out. This could be as simple as a bearing seizing or as bad as the coils in the arnature shorted out.
- Pump may have seized up. Even if the sight glass shows the crankcase is full, the condition of the oil and its ability to lubricate are greatly affected if it is overheated.

Compressor runs but will not air up pass 10 psi

sounds like something has compromised the piston or rings. would advise you remove the cylinder head and inspect cylinder and bore, think you will no doubt find something broken.
