Well, hopefully this will become a "How to" and not a "How not to do", but that remains to be seen.
My AC clutch has been intermittent. I picked up a new clutch, with the plan being to leave the field coil in place, and just replace the pulley and clutch. Easy, right? Not so much. The replacement pulley does not fit over the stock field coil (i.e. giant electro-magnet).
Clutch came off easy. One bolt on the middle, 10mm, and a screwdriver to hold the pulley in place. Bolt isn't very tight, and came right out.
Pulley/bearing sits on the compressor shaft. I had to use a screwdriver carefully against the housing to gently work it off from side to side.
Field coil presses onto the housing. There is a small flange on the housing that the field coil presses on to. Again with the screwdriver, carefully, I worked it out from side to side.
Now the problem. How to press the field coil back on while the compressor is still in the truck and the AC system is still sealed. Not so easy, as it turns out. I have it part way on, using a ball-peen hammer to tap at it. If I did this for about 8 hours, I figure it would eventually seat fully.
Here is where I am:
Not quite there:
I'm hoping to get a 2-jaw puller in there to press it on, using a seal installer over the field coil. It's pretty tight in there, so I'm not optimistic. A friend has some pullers for me to try ....
But, first, I need to go get my credit card and driver's license that I left at the auto parts store.
