New here ! Air compressor froze, can I replace it and the drier after evacuation ?Is there any other things I have to do to get it back running? '85 Ford F-250 6.9 Thanks

 

Which part froze? If the pulley bearing seized you may just be able to replace the clutch asy.
If the compressor failed internally you will need to replace the compressor, orifice tube and accumulator. You will need to also flush the reused parts with solvent and compressed air to dry them thoroughly.
IMHO, I would recommend also replacing the condenser, it can trap debris that can haunt you later. It's not just a series of hollow tubes , imagine a radiator with multiple passages inside each tube.

If you had an FX-15 compressor and it caused Black Death, you will need to replace EVERYTHING except the evaporator. Pull the orifice tube. If it is covered in black goo, you have a Black Death failure.

The clutch engages, but than the only thing that turns is the belt slipping around the pulley of the compressor, that is why I think the compressor failed. Thanks

 

Yep. It seized internally.
You need to pull the orifice tube to determine the extent of the damage. Disconnect the liquid line from the evaporator (the smaller line). The orifice should be just inside the evaporator tube. Pull it out and see how much junk is on it. Post pics if you can.

Note: If you don't see the o-tube in the evaporator inlet, it will be crimped into the liquid line itself. The only way to inspect is to cut it open. Some Ford vehicles had this setup but I don't recall which ones.

 

thanks for your input, will tackle this job tomorrow, just got it evacuated, and more helpful information the man that did the job. very helpful people. thanks again. will keep you posted.

 

Clean as a whistle ! Lucky me. As far as blowing out everything, can I pour solvent down the orfice tube tube, and blow it out?? And do I have to blow one direction, or can I blow the stuff both directions ? thanks, will pour solvent down the condenser, and blow it out to, and all the hoses!!

 

No contamination? You're very lucky Orve. You might think about buying a lottery ticket.
Anyway, you need to remove the lines and flush them one at a time. Then flush the condenser and evaporator (Leave the orifice tube out). Make sure to use LOTS of compressed air to vaporize every last bit of solvent from the heat exchangers. Do not flush through the accumulator, new or old!!
Use a solvent that evaporates fully with no residue. Lacquer thinner works well, but be careful. Isopropyl Alcohol works good also. (not rubbing alcohol, too much water). Don't use mineral spirits, paint thinner, brush cleaner, etc. They don't evaporate well.

Is the system still R12 refrigerant? Are you going to keep it R12 or convert to R134a? Has it already been converted to R134a?
How you proceed depends on the type of oil that is in the system now, the type of shipping oil in the new compressor and if you are converting the system or not.

One thing to consider; The hoses on your AC system are 24 years old. You might want to think about replacing them to prevent problems down the road. They are rubber, similar to heater hoses, and don't last forever. Would you trust 24 year old heater hoses? Just a thought while you have the system apart. Totally your call.

 

Oops, never mind. I see from your other post that you are way past flushing now.

 

thanks lsrx101 !! New problem, accumulator !
got one from Napa, won't work ! Can't secure the body to the bracket, tube in the way. Motorcraft wants $132.oo for one, any suggestions ? Thanks

 

Without seeing it I can only guess.
Tube got bent in shipping or during repair? Wrong accumulator?

Doesn't that accumulator mount onto a bracket that has 2 straps that clamp around the accumulator? Maybe turn the accumulator to get the bolt started then turn it back to the correct position?
I can't visualize how a tube would be in the way of mounting it.

 

Is this it? (it's upside down in the pic).



The long tube looks like it could easily get bent in shipping. It is aluminum so you can probably bend it back into shape pretty easy.

 

You are right, and the picture is correct, but there are two different types. If the pipe coming out of the bottom is a 1/2 inch from the body, won't work! You don't have enough room to use the brackets that hold it in place. Now the other one, OEM, the tube coming from the bottom is a 1&1/4 , now you have enough room to replace the brackets and secure it the right way, like I said, found one at Motorcraft for $132.00 , not going to pay that, because I know I can find one cheaper. Thanks again, was wondering if anybody else had the same problem, and where did they get the part. The one I have from Napa is black, and that was all they had..

 

You can get the one in the picture from Arizona Mobile Air, Automotive Air Conditioning Parts & Equipment - ACKITS.COM.

 

I would like to thank everybody that helped me on this "job." The a/c is working perfect. I now know where to come if I need an help again, Thanks again to everybody ! Charlie
