New AC compressor clutch out

Shims behind the nut or the clutch? I don't have a clutch puller tool. And I just did a quick search and I don't think Advance sells shims for A/C compressors.

Once you remove the nut, the clutch comes off without a puller.

In your situation, you would need to remove shims, not add them.

Okay, so is the air gap the lip between the clutch and pulley? Or somewhere else? And is it.017 inches or mm?

Between the clutch plate and the pulley.

>017 inches. I do not do mm.

Roy

Okay. I will pick up a set of feeler gauges and try this later this evening.

Sounds like a plan.

Roy

Is there a torque spec for that nut?

18 ft. Lbs.

Roy

Well the feeler gauge shows the air gap at.021"

But none of my sockets get to that nut in there, how do you get to it?

You need a deep 6 point socket that is thin walled.

Roy

Is it 15mm? I have deep sockets but specifically thin walled I don't know where to get

Chrome sockets are thin sockets.

I believe it is either a 14 or 15 mm nut.

Roy

Nuts off. Clutch wont budge. I have 2 and 3 jaw pullers and they can't get a grip.

Is the inside of the clutch threaded?

Roy

Looks like it.

Okay, nuts. That is one that is pressed on. It does not show it in my data.

There is a puller that screws into the clutch and pushes it off.

Okay, so got the clutch plate off with the tool. No spacers here. Pulley is held on with a snap ring I think.

Never mind. Looks like I just gotta press the plate back on until it's in spec.

So the scratching is definitely gone. But the compressor seems to go on/off at 2000 rpm. Is it supposed to do that? Can kind of feel it while driving, and doesn't affect the temperature

Kep me updated.
