LCN 4640-3454 – Frequently Asked Questions

1) What does the LCN 4640-3454 motor clutch assembly fit?
It is the geared motor clutch assembly for LCN 4640 Series automatic operators, sold as a service part for that series. If the operator on the door is a different LCN family, this is not the clutch for it, so read the model off the operator cover before ordering.
2) What is a motor clutch assembly in an automatic door operator and why would I be replacing one?
The motor clutch is the geared drive link between the operator motor and the door arm, transferring torque to swing the door. On the 4640-3454 it is a precision geared assembly with a no destruct feature that protects the drive during overload conditions. It is a serviceable component, so when an operator runs but the door does not drive properly the clutch is one of the parts a technician swaps rather than replacing the whole operator.
3) I am specifying a new automatic operator, not repairing one. Is this the right part?
No. The 4640-3454 is a replacement motor clutch that goes inside an existing LCN 4640 Series operator, not a complete operator. For a new opening you want the operator unit itself; LCN publishes a chart for choosing the right automatic operator by application, and its automatic operator catalog section covers the low energy and full power ranges.
4) Does the LCN 4640 clutch have handing, or is one part number good for both left and right doors?
One part number covers it. The 4640-3454 is offered as a single model with no handing, finish, or size options to specify, so there is nothing to choose beyond confirming the operator is a 4640 Series.
5) Is the LCN 4640-3454 clutch a DIY part or does it need a door tech?
This is a commercial service component for LCN automatic operators, meant to be installed by a technician who works on those systems. LCN publishes an installation instructions and templates index covering its closers and automatic operators, and the operator's own sheet is what governs the swap. A property manager buying it should have it fitted by whoever services the operators in the building.
6) Is the LCN 4640 motor clutch rated for high traffic openings like a hospital or school entrance?
It is built as a commercial-grade component for high-traffic automatic door applications, the sort found in healthcare facilities, schools, offices, retail, and government buildings. The no destruct feature is what carries it through overload events on doors that cycle constantly.
