Donnie, I once cracked a fan clutch housing retainer bolt hole shoulder while tightening one to torque spec. Slow loss of silicon oil. Could not stop leak no matter what I did. Ended up replacing same. Lesson for me, don't trust aluminum that's older than a week, especially the brittle alloy used in those clutch housings. If I can work around removing it, that's the way I go. Those critters cost too many dinero to mess with. I'd rather pop the shroud and the blades (3 little allen capscrews, they gotta come out anyway) and leave the clutch alone. Maybe I'm just gunshy about aluminum stuff. Got some great stories about aluminum parts which break mysteriously..
