This project got put on the back burner for a while. Here are some pics of the clutch/pulley, coil. There was plenty of clearance to remove/adjust clutch after pulling wheel and dust shield. I didn't have to unbolt compressor. I picked up a copy of "automotive heating & air conditioning" by Thomas Birch
and it has some pretty good repair/troubleshooting info for many makes and models. Looks like the clutch was contaminated and or the coil was malfunctioning. I tested the condition of the compressor by spinning the hub & shaft and it has some drag and is not very smooth. Although the pulley bearing felt pretty smooth (& I tried to regrease it) after reassembly it still sounds like its ready to come apart-so I have to get a new pulley on there or change out bearing (cheapest way)-but its staked/pressed in. I think I'm just gonna go the AC pulley delete route. The shop down the street will cut me a deal on evacuating the old R134 so I can remove the compressor. Its gonna take some cash to put the AC right again. I think the recommended procedure at this point would be to also flush system, replace the accumulator, orifice tube, install filter?
