Success!

My approach worked. Here are the steps from the "missing manual"...

1. Drill the innermost rivets to release the clutch plate from the spline mount;
1a. Sheer the rivet tailings with a chisel (if necessary);
1b. Pry the clutch plate from the spline mount (if necessary).
Note: Look for and retrieve the small spacer(s) nestled behind the clutch plate.

2. Obtain a smallish three-jaw puller with flat-end hooks--grind/file hook ends as necessary for suitable fit.
3. Thread 8mm hex (or Torx) head into compressor shaft;
4. Finegal the puller around the edge of the spline mount;

Image

5. Twist the threaded push rod until the spline mount is free.

The snap ring that holds the pulley is now accessible. I'll remove the pulley next (with a larger three-jaw puller) which provides access to the field coil and the snap ring that holds it. I may also replace the bearing in the pulley 'cause, why not.

Oy. So straightforward a job turned into a onery chore because of a little oxidation (and inexperience with immediate alternative courses of action in such circumstances.)

Glad to learn you finally got the darn thing off. And thanks for your detailed posts, to which I'll refer if I ever face the same problem.

Rotor pulley may need replacement because it appears to have a crispy friction liner with missing surface.

You're right. From the photo, it does appear pretty rough. If that's the case, replacing the entire clutch probably would be the way to go since I'm not sure whether the pulley is available separately. Tim would know.

The fakakta field coil I removed from the compressor has a rather prophetic build number printed on the back of it. <smirk>

Nice work around on a unit with no puller access. Glad to see you got it fixed

A lot of labor however.
Commercial shops would replace the compressor in less time than it took to drill the rivets & modify the puller.
