HySecurity MX002390, Spring Assist Assembly, StrongArmPark DC 14
HySecurity MX002390 is a spring assist assembly for select HySecurity StrongArmPark DC 14 barrier arm operator applications. Nice HySecurity StrongArmPark DC parts documentation lists MX002390 as "Spring Assist Assembly, StrongArmPark DC 14" for StrongArmPark DC Models DC14.
This assembly is used to help support the lifting and balancing load of the longer StrongArmPark DC 14 arm configuration. Current listings describe it as a replacement spring assist assembly with rod ends. Because spring assist hardware is tied to arm length, arm weight, mounting geometry, and operator model, MX002390 should be selected only after confirming the installed operator and HySecurity parts diagram.
What This Spring Assist Assembly Does
The spring assist assembly helps counterbalance and support the barrier arm during raising and lowering. In the approved StrongArmPark DC 14 setup, the spring assist reduces strain on the drive system and helps the operator move the arm in a smoother, more controlled way.
A worn, stretched, broken, loose, misadjusted, or incorrect spring assist assembly can contribute to arm imbalance, slow movement, harsh movement, drive strain, motor load, uneven travel, difficulty holding position, or repeated wear on related drive parts. Similar symptoms can also be caused by a damaged arm, incorrect arm length, bent arm hardware, worn rod ends, loose mounting points, bad gearmotor, worn drive belt, gearbox binding, physical stop misadjustment, sensor target issues, low battery voltage, or controller problems.
Compatible With
Use HySecurity MX002390 only where the operator parts diagram, original spring assist assembly, or HySecurity documentation confirms this part number.
- Select HySecurity StrongArmPark DC 14 applications where MX002390 is listed as the spring assist assembly.
- StrongArmPark DC Models DC14 where the parts diagram lists MX002390.
- Repairs where the original spring assist assembly is marked, listed, or cross-referenced as HySecurity MX002390.
- Applications where the barrier arm length, arm hardware, mounting points, rod ends, and spring assist geometry match the HySecurity parts diagram.
- StrongArmPark DC 14 arm balance repairs where diagnosis confirms the spring assist assembly is worn, damaged, loose, broken, or no longer serviceable.
Important Compatibility Warning
Do not order MX002390 based only on the words "spring assist." This part is listed for StrongArmPark DC 14 applications. StrongArmPark DC 10, WedgeSmart DC, StrongArm, StrongArmPark hydraulic operators, SwingSmart, SlideSmart, SlideDriver, HydraSwing, and other HySecurity operator families may use different arm hardware or no matching spring assist assembly.
Spring assist parts are balance-related. Using the wrong spring assist assembly, wrong arm length, wrong arm hardware, or incorrect mounting position can overload the drive system or cause unsafe arm movement. Always confirm the arm length, arm material, installed hardware, and operator parts diagram before ordering.

Technician Note
Before replacing MX002390, inspect the spring, rod ends, mounting brackets, pivot points, fasteners, arm length, arm material, physical stops, drive belt, gearmotor, gearbox, and sensor target. A heavy, slow, or uneven arm may be caused by the spring assist assembly, but it can also come from arm damage, binding, drive wear, physical stop misadjustment, low battery voltage, or controller/sensor issues.
Spring assist assemblies can store mechanical energy. Do not remove or adjust spring-loaded arm hardware without properly supporting the arm and following the service procedure. If the arm is not supported, the spring or arm hardware can move unexpectedly.
Before Ordering, Confirm
- The required part number is MX002390.
- The operator is a HySecurity StrongArmPark DC 14 application where the parts diagram lists MX002390.
- The installed operator is not a StrongArmPark DC 10 unless the parts diagram specifically lists MX002390.
- The repair requires the spring assist assembly, not a drive belt, gearmotor, gearbox, physical stop bumper, arm bracket, or complete arm assembly.
- The arm length, arm type, spring mounting points, rod ends, and hardware match the HySecurity parts diagram.
- The existing arm is not bent, cracked, overweight, poorly balanced, or damaged from impact.
- The drive belt, gearmotor, gearbox, physical stops, and sensor target have been inspected for related problems.
- The package includes the expected spring assist assembly and any required rod ends, fasteners, or mounting hardware, or those items are ordered separately if needed.
Installation and Service Notes
- Disconnect and secure operator power before servicing arm balance or spring assist hardware.
- Support the barrier arm before loosening spring assist hardware.
- Do not work under an unsupported barrier arm or spring-loaded arm assembly.
- Use caution around spring-loaded components, rod ends, pivot points, and pinch points.
- Do not substitute generic springs or change spring mounting points to force the arm to balance.
- After installation, verify smooth arm movement, proper balance, stop contact, drive response, and controller feedback.
- Inspect the drive belt, gearmotor, gearbox, physical stop bumpers, and sensor target after adjusting or replacing the spring assist assembly.
- Verify all required safety devices, access control safety inputs, stop circuits, and controller protections before returning the operator to service.
Professional Advisory
Spring assist assembly replacement should be handled by a qualified gate technician when the repair involves spring tension, heavy or long barrier arms, arm balance, rod ends, pivot hardware, drive strain, impact damage, physical stop adjustment, or unknown prior modifications. Do not bypass controller protections, position sensors, limit controls, stop circuits, access control safety inputs, photo eyes, safety edges, or any required safety devices to keep the operator running.
