GWFLORID Maintenance Manual 210 Electromagnetic Clutch Clutch composition Electromagnetic clutch consists of an armature, a solenoid, and a pulley. Areas of importance during clutch usage Because the joint of the electromagnetic clutch operates under high speeds, separation-joint marks on the pulley and armature are completely normal, and do not harm clutch usage. The clutch's operating voltage must be consistent with the specified voltage rating. Too high or too low will affect its normal usage. The clearance between the coil and the pulley is very important. If too big, the effect of the magnetic field reduces. If too small, the high speed pulley rubs against the fixed coil, causing the clutch to burn. The clearance between the armature and the pulley is also very important. If too big, it leads to insufficient clutch pull-in force. If too small, it may cause armature damage. Clutch removal 1. Seize the clutch's triangular piece and secure the clutch's armature with a clamp. Then take down the inner hexagon lock screws of the main shaft with an inner hexagon spanner. 2. After removing the lock screws, manually grasp the triangular piece and take out the armature, at the same time remove the clamp spring with the circlip pliers. 3. Remove the clutch's pulley with pullers as shown, and remove the compressor pulley and its bearing. 4. The gasket on the main shaft is used to adjust the clearance between the pulley and the armature. Use it to adjust the clearance value to be as specified during installation, and do not lose it during removal. 5. Remove the mounting screw from the solenoid coil connector with a screwdriver, and use circlip pliers to take down the retaining ring inside the coil and remove the solenoid coil. |
