NOTE: DO NOT drive or pound on clutch hub or shaft.
Installation
1) Install shaft key into hub key groove. Allow key to
project approximately 1/8" out of key way. Shaft key is curved
slightly to provide an interference fit in hub key groove.

are clean before installing clutch plate and hub assembly. Align shaft
key with shaft key way and place clutch plate and hub assembly onto
compressor shaft.
3) Hold hex portion of Installer (J-9480-B) with a wrench.
Tighten center screw to press hub into shaft until there is .020-.040"

against crankshaft shoulder. Use Thin Wall Socket (J-9399) and Clutch
Hub Holder (J-25030). Tighten shaft nut to 10 ft. lbs. (14 N.m). Spin
pulley rotor by hand to ensure rotor is not rubbing on clutch drive
plate.
