New ac compressor clutch out
1995 CHEVROLET 1500

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?
Sep 12, 2019 at 4:25 AM
Between the clutch plate and the pulley.
>017 inches. I do not do mm.

Okay. I will pick up a set of feeler gauges and try this later this evening.
Sep 12, 2019 at 4:29 AM
Sounds like a plan.

Is there a torque spec for that nut?

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.

Is it 15mm? I have deep sockets but specifically thin walled I don't know where to get
Sep 12, 2019 at 4:43 PM
Chrome sockets are thin sockets.
I believe it is either a 14 or 15 mm nut.

Nuts off. Clutch wont budge. I have 2 and 3 jaw pullers and they can't get a grip.
Sep 13, 2019 at 5:08 PM
Is the inside of the clutch threaded?

Looks like it.
Sep 13, 2019 at 6:07 PM
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.
Sep 14, 2019 at 1:59 PM
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
Sep 14, 2019 at 4:38 PM
Kep me updated.

Compressor turns on and off when over 2000 rpm. Can kind of feel it while driving. But no scratching like before. Low side 25 psi and high side 250
Sep 14, 2019 at 5:54 PM
Low side is low. At 2k does the low side drop off more.

I think it did just a hair, think it's a Freon problem?
Sep 14, 2019 at 6:18 PM
Yes. The low pressure switch shuts down the system when the low pressure hits 20 lbs.
That indicates a bad expansion valve.
Roy

can't be. The orifice tube and condenser are maybe a month old. I probably just measured it wrong.
Sep 15, 2019 at 6:30 AM
The gauge is accurate.
Yes, it can be. If the tube is defective or clogged, it will do this.
Take the readings again and post a picture of the gauges at 2k.

The pressure is also in the 20's before 2k.
Sep 15, 2019 at 6:54 AM
I know. You mentioned that already.
