Product Overview
The HySecurity MX001403 Drive Belt Motor Pulley is a 24 tooth, 9 mm wide pulley that mounts to the motor input shaft on compatible HySecurity gate operators. It is used in the belt drive portion of the operator where motor rotation is transferred through the drive belt system.
A worn, loose, damaged, or incorrect pulley can cause belt tracking problems, belt wear, slipping, noise, uneven drive transfer, or poor operator performance. This part is commonly ordered when the existing motor pulley teeth are worn, the set screws no longer hold properly, or the belt drive assembly is being serviced.
This is a dimension-specific pulley. Tooth count, belt width, bore/input shaft fit, and set screw position must match the installed assembly. Similar HySecurity pulleys may look close but may not align correctly with the belt or companion pulley.

- Match the motor input shaft and set screw arrangement
- Inspect belt condition and alignment
- Check companion pulley and belt tension

Important Ordering Warnings

Professional Advisory
HySecurity gate operator repairs often involve moving gates, stored energy, high voltage, batteries, and monitored safety devices. Electrical diagnosis and any unsafe gate movement should be handled by a qualified gate technician. Never bypass required entrapment protection or limit controls to keep an operator in service.
