A/C Compressor Servicing: Installation
- Install shaft key into hub key groove. Allow key to project approximately 1/8" (3.2 mm) out of key way. Shaft key is curved slightly to provide an interference fit in hub key groove.
- Ensure frictional surface of clutch plate and clutch rotor 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.NOTE: DO NOT drive or pound on clutch hub or compressor shaft, as compressor could be damaged internally.
- Hold hex portion of installer (J-33013) with a wrench. Tighten center screw to press hub into shaft until there is .015-.025" (.38-.64 mm) air gap between frictional plate and clutch rotor.
- Install new shaft nut with a small diameter boss of nut against crankshaft shoulder. Use Thin Wall Socket (J-9399) and Clutch Hub Holder (J-25030). Tighten shaft nut to 96-192 INCH lbs. 11-22 N.m). Spin pulley rotor by hand to ensure rotor is not rubbing on clutch drive plate. See Figure.
