i posted this in the a/c forum but have had zero response i need some help with a factory york type compressor. thanks https://www.ford-trucks.com/forums/s...d.php?t=386071

 

My factory book, page 36-30-12 calls out Ford Part No. C9AZ-19577-A oil, and from what I am seeing, the compressors all shown in this section look to be the York-type. I also have a neat drawing of how to make your own York oil level dipstick. I can scan this tomorrow at work and send it to ya...along with several pages of York/oil-related data.

EDIT:

Oh, yeah, on page 36-30-16, the York takes 10 fl. oz.

Oil spec is listed on this page as ESA-M2C31-A, same Ford number following the spec no.

ALSO, the max oil level for a horizontal York is 1-3/16", min level is 13/16". There is a footnote that states - Do not bring the oil level to the maximum if you are in between the min and the max. If the level is below minimum, add oil up to minimum level only.

The max oil level for a vertical York is 1-1/8", the min level is 7/8".


EDIT #2:

I just re-read your msg about 134 - Sorry, I do not know if the Ford part number is compatible with the 134...

 

is there any other type of oil you might suggest to use in the pump is the oil in the pump different than the oil used in the rest of the system

 

I think it is the same oil that is in the freon. I think I will go Googling for 134 FAQs and see what else there is to this conversion stuff...


EDIT:

Here are some "bites" of info I just Googled...

If you're mulling a change to R134a, consider this: you can retrofit for well under the cost of a full R12 charge. The worst part of the change is draining the compressor and replacing the mineral oil (incompatible with R134a) with ester oil. This will only cost you $5 and some time, and the ester oil will work with R12 if you decide to switch back.

SPECIAL NOTE - "Ester oil is preferable to PAG in a retrofit, as it will mix fairly well with any remaining mineral oil. It was originally thought this was not the case, but consensus nowadays is that they mix satisfactorily. Ester is also less corrosive than PAG. As an additional benefit, R-12 will also work with Ester should you ever wish to convert back. If you follow these guidlines, all you would need to do to revert to R-12 is completely vacuum all R134 out of the system and then simply reinstall R-12."

Another good E-Bay company to consider for Freon alternatives!

Ebay Links don't work.

Post the item number instead.

Also, Please use the edit feature.

 

Sorry! You all familiar with E-Bay, go to Item 7976983340 - then click on View Seller's Other Items Store View. Lots of goodies for 134 conversion as well as Freon alternative products...Cool!

 

Here is another link which has lots of helpful information on York style compressors. If you need a new one and want to upgrade to a heavy duty unit then this will help.

Start with the york completely empty, put about 10-12 oz of straight 30 HD motor oil in there. Get a little piece of wire and scribe a mark on the wire at the top of the oil line, and you'll have a dip stick.
Depending on use add oil in the fill hole on the side. I'll be fine.
You won't need an in-line oiler but you will want a coalesent(sp) filter before your air tank.

 

No you can't use motor oil in the York compressor for AC. It will contaminate the refrigerant in the System. It must be a refrigerant compatible oil like ester oil or pag oil for R134a, etc...

However, if you do decide to make an on board air compressor using a York style compressor then yes you can perform the motor oil idea.

 

Oh, my bad. I thought you where converting your ac to air.

Isn't the lube for the york in the refrigerent stuff already. I've never seen anyone oil there AC system as regular maintenence. My truck just has the wing window cooling system, oh and the vent.....

 

The R12 does have oil in it already, but still must get the R12 compatible oil added to the crankcase when serviced as far as I know. The R134a is a bit different in that even after the crankcase oil is added you must add more oil to the refrigerant you charge the system since R134a has no lubricating oil in it in the containers it comes in as far as I know. I may be a bit off here so maybe someone else can be more precise.

Some compressors are lubricated by oil splash in the crankcase and others rely on the oil in the refrigerant itself. This area is easy to get confused on. Still the oil used must be compatible with the type of refrigerant used.

Also, my system has lost it's charge, so I'll be working on it again soon. I'll be able to take a closer look at the oil used, where it should be added and how much. This Ac stuff is sure a hot topic recently.

 

i just got my 609 epa certification today so now i am free to buy r12 awesome so now i can just refill with r12 i found a whole bunch cheap only 5.00 a can. you can get certified too take the test online it costs 20.00
