the hub onto the shaft. Tighten the body several
turns, remove the installer and check to see that
the shaft key is still in place in the keyway before
installing the clutch plate and hub assembly to its
final position. The air gap between frictional
surfaces of the clutch plate and clutch rotor
should be 0.38-G.64mm (.015-.025").
• If the center screw is threaded
f u l l y
onto
the end of the compressor shaft, or if the
body of the installer is held and the center
screw is rotated, the key will wedge and
break the clutch hub.
7. Remove installer J-33013, check for proper
positioning of the shaft key (even or slightly
above the clutch hub). Install the shaft nut. Hold
the clutch plate and hub assembly with clutch
hub holding tool J-33027 and using shaft nut
socket J-33022, tighten the nut against the
crankshaft shoulder to 11-22 N-m (8-16 ft. lbs.)
torque, using a 0-35 N-m (0-25 ft. lbs.) torque
wrench.
8. Spin the pulley rotor by hand to see that the rotor
is not rubbing the clutch drive plate.
