Need help with Motorcraft YCC-337 Compressor

I have foolishly misfiled the instruction sheet that came with my new YCC-337 Motorcraft AC compressor. Specifically, I need to know how much oil the compressor has in it from the factory. If anyone has the instruction sheet for this part number, or knows where I can find it online, please let me know. Thank you very much.

You may want to consider emptying out the oil and refill with 7 ounces.

This chart may help.

Thank you for your reply, Ray.


Here is the situation. I've replaced every part of the system, and it wasn't until after I had the compressor installed that I realized I lost the instruction that came with it. It's a really nasty job having to remove the compressor, just to drain the oil. Does anyone know how a reliable way to drain a compressor in situ?



As a further note to my somewhat large brain fade, the new condenser came with a replacement rad support decal warning that the refrigerant quantity is different when using that part number. You've probably guessed by now, that I've lost that, too. My plan here, is to charge the system with several ounces less than called for, and adjust the amount using my gauges.


Thank you to any and all who may be able to help.

I have replaced two compressors with aftermarket ones and I have never added additional oil to the compressor. I tried but they never took additional oil. I never installed a Motorcraft brand. Never had issues after at least five years. Take a look at this info.

Hi Don,

Compressor is easily removed & installed from the top. Simply remove the l.h. fan, remove the 4 bolts on compressor and both compressor & manifold will lift out. Takes less than 1 hour.

Some people insist making a lot of work for themselves by removing from the bottom.

If I were you I would:

Disconnect manifold from compressor
Remove compressor and drain oil
Reinstall above

Refill with 7 oz oil through the manifold gauge hose.

Or:

Refill compressor before reconnecting back to manifold (suction & discharge), just be careful no oil leaks from the hoses.

The above procedures worked for me when I replaced my ac system components and would save you a lot of stress.

The only thing I fought with was installing the drier / accumulator on the firewall connection, other than that this job was not difficult and I am not an expert.

Ray

I am thinking seven ounces is way too much oil to add. The way I read the chart that was posted is that the total oil in the system is seven ounces but you have to remember that oil is contained in all the components of the system. If you just replace one component then amount is significantly less. I had a chart of oil by replace component I will try to find and post.

^^^^ Agreed. The receiver / dryer typically has a few ounces in it, as does the condenser. When I replaced the condenser in my 05 a few years ago (got hit by a rock in just the wrong place ) A quick look at the Ford shop manual I found a list of how much oil to add when specific components are replaced. I think the manual stated to add 2 or 3 oz PAG 46 if condenser is replaced.
