  • Page 35: Clutch-Brake Maintenance

    Clutch-Brake Maintenance  WARNING Always disconnect the power supply before making any adjustments or servicing the stitcher This stitcher is equipped with a solenoid actuated, continuous trip, wrap spring clutch-brake unit. It is a dependable device and seldom needs service. But should a malfunction occur, the following information is a service and troubleshooting guide for the maintenance of this unit.
  • Page 36 Clutch and Brake Springs With the brake engaged (full limit of output), the input hub should be free to rotate by hand. With the clutch engaged, the input and output hubs should rotate together. If the unit does not rotate in either of these modes, the clearance between the hubs of the unit on the shaft may have been disturbed or damaged.
  • Page 37 Disassembly (See figure 29) To disassembly the Clutch-Brake unit (850677 or 850678) it will be necessary to remove the Drive Pulley (7678) from the stitcher by removing the V-Belt (850730), Retaining Ring (P7863), and Clutch Anchor Screw (7681). Disconnect the Ground and Solenoid wires, and swing the anchor strap (FC9656) clear of the Drive Pulley Assembly and slide it off of the Drive Shaft.
  • Page 38 Note: At this point it may be necessary to reselect one (1) of the nine (9) Control Collar slots for the Brake Spring Tang (release Actuator Lever, remove the Clutch Spring tang from the slot, then move Control Collar axially toward the Input Hub end and rotate it opposite to the drive direction to pick up the next slot).
  • Page 39 Lubrication The clutch-brake unit is designed with the bearing parts made from sintered metal that has been impregnated with oil and normally do not need to be re-lubricated. In cases where there is severe duty, the unit may be re-oiled or flushed out with minimal or no disassembly by using a light bearing oil as used in manufacture (Shell Bearing Infusion Oil #33).
