BP554 Measuring Wheel Tension Spring Setting

Unplug machine from power source.  Remove Key Drum Assembly.  The tension on the clock spring is what returns the measuring wheel back to its starting position as soon as the feed cycle is completed and the clutch roller is released from contact with the measuring wheel.  This tension is not critical, but must be enough to return the measuring wheel quickly, But not enough to cause so much resistance to the measuring wheel that slippage is encountered when the clutch roller is turning it during the feeding cycle.
On the model 554 the clock spring is carried in a cup molded into the measuring wheel.  To adjust the tension it is necessary to remove the control cover plate assembly in a unit which carries the measuring wheels.

Model 554
With the stop discs set as shown above (pointer set for 4" lengths), 1/2 turn counter clockwise.
