Installed new air compressor, drier, condenser and orifice tube. Vacuumed down and recharged fine. Two weeks later the clutch is rattling and there is shredded metal around it. I hear there is an adjustment that can be made on these. Is it worth doing that?

Good afternoon,

Since there is metal, no. The clutch is no good. You will need to replace the compressor again.

What were the pressures after you installed all the new parts?

Sounds okay. The low side is a little high. It should be 25-30 rock solid. It should never vary at all.

The new compressor is warranty anyway. I would just change it out instead of spending more money.

How much oil goes into the compressor? 4oz? The paper in the kit says 8 oz. For the system, so 4 for the compressor, 2 for the accumulator and 2 for the condenser? The compressor says it has 3 oz in it and to fill to manufacturers recommendations.

Okay, below is the spec for the oil just for the compressor.

- Without Aux. A/C - 240 ml (8 fl oz)
- With Aux. A/C - 330 ml (11 fl oz)

Well put a new compressor on it. And immediately the clutch on this one started scraping and shredding.

Customer left. But it would scrape when you turned it on, run quietly, and when it turned off the clutch would scrape and move a little bit with the pulley. Metal shavings too. They bought the same brand as the last one, cause it was under warranty. They decided to save up for an AC Delco one

However these style compressors have an air gap that can be adjusted. Do not if it's worth adjusting but I don't have the tools to do it.

Got a compressor on there, and now it won't work. It will only turn on when I run a jump wire to the sensor that plugs into the back of the compressor. It plugs into an orange switch that I transfered from the old one.

That is a high-pressure switch. It is a normally closed switch. If you have to jump it, the switch is no good.

But jumping it engages the clutch, even if the AC button is off and even if the truck is off.

Again, it is a normally closed switch. If you jump it, the switch is bad. It only opens when the high pressure exceeds 375 lbs. To protest the compressor.

How do you know if it's a high pressure cut-out or a low-pressure cut-out switch? There are many options. The color of this one looks orange.
