A/C Clutch replacement
1994 F-150 302 auto 4x2
I have a new A/C Clutch that I would like to install because this one isn't working. it came with instructions.. and I started working on it.. but after a while it didnt make any sense and had to stop. Anyone have any instructions (preferably with pics, if not its ok) that is pretty much step-by-step?

2. Pull clutch hub and shims from compressor shaft. If hub cannot be pulled from compressor shaft, screw an 6mm bolt into the shaft hole of the clutch hub to force the hub from the shaft.

3. Remove pulley retaining snap ring.
4. Pull the pulley and A/C compressor pulley bearing (2990) from compressor.

Installation
1. Clean pulley bearing surface of compressor head to remove any dirt or corrosion.
2. Install pulley and A/C compressor pulley bearing on compressor. The bearing is a slip-fit on the compressor head and, if properly aligned, it should slip on easily.
3. Install pulley retaining snap ring with bevel side of snap ring out.
4. Place one nominal thickness spacer shim inside the hub spline opening and slide the hub on the end of the compressor shaft.
5. Thread a new 6mm hub retaining bolt into end of compressor shaft. Tighten hub retaining bolt to 11-13 N-m (8-10 ft-lb). DO NOT USE AIR TOOLS.
6. Check clutch air gap between clutch hub and pulley mating surfaces with a feeler gauge. The air gap should be between 0.45 and 0.85mm (0.018 and 0.033 inch). Check at three locations equally spaced around the pulley.

7. If clutch air gap is not within 0.45 to 0.85mm (0.018 to 0.038 inch), repeat Steps 4 through 6 with various thickness shims until air gap is within specified limits.
8. When installing a new clutch, cycle it ten times at idle to burnish the clutch and prevent slippage.
