Clutch Coil & Bearing Assembly: Installation
- Align clutch reference marks made during removal. Position Clutch Coil Installer (J-33024) over internal opening of clutch coil housing and align with front head of compressor. Position Puller Crossbar (J-8433-1) and Through-Bolts (J-33026) so Forcing Screw (J-8433-3) is centered in clutch coil installer center hole. Ensure through-bolts are fully threaded into holding fixture.
- Tighten forcing screw against installer to press clutch coil onto compressor front head. Ensure clutch coil and installer stay aligned during installation. When clutch coil is fully seated on front head, stake front head and clutch coil. Using a 1/8" (3.2 mm) punch, stake clutch coil inner ring in 3 places, 120 degrees apart. Stake size should be 1/2 the area of punch tip and 0.010-0.015" (0.28-0.38 mm) deep.
- Position Pulley/Bearing Installer (J-33017) and Pulley/Bearing Puller Guide (J-33023-A) over inner race of pulley bearing. Position Puller Crossbar (J-8433-1) and Through-Bolts (J-33026) so Forcing Screw (J-8433-3) is centered over puller guide. Ensure through-bolts are fully threaded into holding fixture.
- Tighten forcing screw against puller guide to press pulley and bearing assembly onto front head of compressor. Ensure puller guide and front head of compressor stay aligned during installation. Install snap ring.
- Install shaft key into clutch plate and hub. Ensure shaft key protrudes about 1/8" (3.2 mm) out of keyway. Ensure friction surfaces of clutch plate and pulley are clean. Ensure shaft key and keyway in hub are aligned and position clutch plate and hub onto compressor shaft.
- Install Clutch Plate/Hub Remover/Installer (J-33013-B) with forcing screw in installation position. Body of remover/installer should be backed off from hub enough to allow forcing screw to be threaded onto compressor shaft.
- Hold forcing screw and tighten installer body to press hub onto compressor shaft. Before pressing clutch plate and hub to final position, remove installer and ensure shaft key is still in keyway. Continue pressing clutch plate and hub until air gap between friction surfaces is 0.020-0.030" (0.51-0.76 mm).
CAUTION:
When installing clutch plate and hub, if forcing screw is fully threaded onto end of compressor shaft or installer body is held and forcing screw is rotated, the shaft key will bind and break the clutch hub.
