how is the ac compressor clocked?

[JDEstill]

I am going through my ac system again - the cheap compressor I used last summer died - and have a problem. A friend of mine did the R&R on the compressor last week for me. Now I am flushing lines, hooking everything back up, getting ready to evacuate and charge it, and there is an electrical connector I can't get back on. This is the two prong connector that is on the back of the clutch, so the connector slides in between the clock and the compressor housing. Right now the lower mounting boss on the alternator support bracket that bolts to the front of the compressor is blocking this connector from going on. Looking at the thing from the front, the connector is a little past 3 o'clock, not quite to 4. Is that about where this connector is supposed to be? If the whole compressor needs to be rotated 90degs that will put this connector at about 6 o'clock. On the back side the compressor discharge is a little bit before 12 o'clock. Is that right? Rotating the whole compressor 90 degs would put the discharge around 3 o'clock, or a little before.

Can someone tell me if the whole compressor is clocked wrong, if maybe the clutch assembly is clocked wrong, or if everything is in the right spot and something else must be going on?

Thanks

John,
My original compressor has an electrical connector at about 5 o'clock.

Don't be too judgmental about the cleanliness of my engine bay, please!!!

I haven't changed one of those clutches in some years but iirc that clutch coil is pressed on with a light press fit around the pulley bearing. It should have been marked and put back right when friend worked on it. Have him do over.

I did the r and r. No it needs to be sent back for one with the tabs in the right spot. The one that was replaced had the tabs in the 4-3 oclock position. Clearly different from the original one. There is only one position that the compressor can be mounted. The lines on the back will not bolt up in any other position.

Yes, we looked it over and pondered it, and the thing was just assembled wrong. The compressor is installed correctly, but the manufacturer did not put that connector on in the right spot. I got the clutch removal tools from O'Reilly's and took apart the old compressor to see how hard it is to do, and just how that thing goes on. Once you get the clutch off, and the pulley, then there is a another ring with that electrical connector on it which is press fitted on. Pull that off and you can clock the connector any which way you please. We could do that with the new compressor, but heck, its a brand new unit. I don't want to risk taking it apart, not getting it back together quite right, having a problem and no warranty. So I'll just get another compressor headed this way. arrghhh... I need my a/c!

btw, thanks for the picture Dan, I appreciate it!

Ok sounds good. Hopefully the next one is right.

John,
Hate to say it but the "lack of quality" doesn't surprise me.
I wasted 2 days looking for a direct replacement horn for a vehicle they made +millions. Let alone trying ro locate parts for a vehicle they only made 2 years. Pathetic. No one compensates for the labor. Rant over.

On second thought, If you fix it yourself who would even notice should you have a warranty problem? Like JerryL said quality is poor and they might all be "clocked" the same.

Let's look at this statement and the accompanying information.
1. You know how to fix it today.
2. You have the ability to fix it today.
2. You have the parts to fix it today.

Are you sure you need your a/c.

I woke up this morning in the same exact situation as you. Since I was armed with the same information as you,I made the necessary adjustment to get my air conditioner back in service because I could.
Do you know why I made a different choice than you did?

Because I NEED my a/c !
