Hi all,
Anybody here ever replace the A/C compressor clutch on a ford Truck?
This is a 1990 F150, 5.0. I am getting a loud-ish curnchy grinding
bearing noise that I think is comming from said clutch. I am 90%
sure that is the culprit and will confirm that, if it ever stops
raining here in NE Mass. Any tricks (ie. special tools, hints,
tips, etc.)I ought to know about before I dive in on this one?

It always helps when i tap the collective mind here at RCM before
getting in too deep. When ever I don't, I end up doing so
mid-project to figure out how to finish.

I appreciate for any ideas!

Gee, you beat me to it... Guess what's sitting out in my driveway
Right Now - a 1999 E-250 Van that isn't going anywhere until I replace
the AC Clutch Pulley with the disintegrating ball bearing.

N0oooo, it couldn't be one of the easy idler bearings... :-(

Hey, count your blessings. At least with a truck it's on the top
and easy to get to. On the van with the 5.4 V8 it's on the very
bottom of the stack right above the Twin I-Beams. Creeper time.

Go to the Motorcraft site, and they have a parts lookup page
(activant.com) that drills down to the pieces you need, with pictures.

It's a fairly simple gidge - the pulley has an offset flat face and
a bearing with a large center bore that rides on a boss on the nose of
the compressor. The magnet is a ring that sits behind the pulley.
And the hub bolts to the compressor input shaft. The magnet sucks the
hub into the pulley, and away you go.

Note: Use a 6-point socket to get the clutch hub center screw out.
That one almost turned into a DAMHIKT moment, but I do need a fresh
screw now.

The big question I have is, what retains the idler bearing inner
race on the nose of the compressor? Circlip, nut or Loctite?

WARNING: I can foresee a huge problem - be careful what you clean it
up with before you start reassembly, lest you melt the input shaft
seal and let all the Freon loose. Which would be even worse than a
"Magic Smoke" incident.
