HySecurity MX4624-P, GEARBOX, SWING 535 w/ OIL
HySecurity MX4624-P is a replacement gearbox supplied with oil for select HySecurity SwingSmart 535 and SwingSmart CNX swing gate operator applications. Current listings identify this part as "GEARBOX, SWING 535 w/ OIL" and also as "GEARBOX, SWING CNX w/ OIL," with MX4624 shown as a related base part number.
The "-P" suffix may indicate a packaged service version of the gearbox. Because gearbox fitment can depend on operator generation, chassis style, drive arrangement, output shaft, mounting points, and retrofit history, this part should not be selected by description alone. Confirm the operator model, serial number, original gearbox part number, and HySecurity parts diagram before ordering.
What This Gearbox Does
The gearbox transfers drive force from the operator motor and drive assembly to the swing gate arm mechanism. In a swing gate operator, the gearbox is a load-bearing mechanical part that must match the operator's intended torque, mounting, shaft alignment, and gate movement geometry.
A worn or damaged gearbox can cause noisy operation, slipping, rough movement, uneven travel, binding, backlash, oil leakage, loss of drive, or failure to move the gate under load. Similar symptoms can also be caused by a weak motor, damaged output components, loose mounting hardware, incorrect arm geometry, gate binding, failed bearings, physical stop issues, or controller-related movement problems.
Compatible With
Use HySecurity MX4624-P only where the operator parts diagram, original gearbox label, or HySecurity documentation confirms this part number or the approved related base part number MX4624.
- Select HySecurity SwingSmart 535 applications where MX4624-P or MX4624 is listed as the gearbox with oil.
- Select HySecurity SwingSmart CNX applications where MX4624-P or MX4624 is listed as the gearbox with oil.
- Repairs where the original gearbox is marked, listed, or cross-referenced as HySecurity MX4624-P or MX4624.
- Applications where the gearbox mounting, shaft/output arrangement, oil-filled configuration, and operator generation match the original installation.
- Retrofit or service applications only where the current HySecurity parts diagram confirms this gearbox for the installed operator.
Important Compatibility Warning
Do not order MX4624-P based only on the wording "SwingSmart" or "gearbox." Current listings use both SwingSmart 535 and SwingSmart CNX wording for this part, and HySecurity has separate SwingSmart 535 and SwingSmart CNX documentation. Verify the correct operator model, serial number, gearbox part number, output configuration, and parts diagram before ordering.
Gearboxes from SwingSmart DC, SwingSmart CNX, SwingSmart 535, SlideSmart, and other HySecurity operators may look similar in photos but are not automatically interchangeable. A wrong gearbox can cause alignment problems, mounting issues, incorrect travel behavior, premature wear, or unsafe gate movement.

Related Parts and Accessories
The correct related parts depend on the operator model, generation, arm configuration, and the reason the gearbox is being replaced. Inspect the full drive area before ordering only the gearbox.
- MX4624 base gearbox with oil - related base part number, verify relationship to MX4624-P.
- Motor or gearmotor components - separate parts unless the current package specifically includes them.
- Output shaft, crank, linkage, or swing arm hardware - related drive components that should be inspected for wear or damage.
- Mounting fasteners, bushings, and spacers - verify whether they are included or need to be reused or replaced.
- Controller or motor drive module - separate electrical control components and not part of the gearbox.
- Limit, sensor, reset, and safety devices - separate components that must remain connected and functional after service.
Technician Note
Before replacing MX4624-P, inspect the gate and operator drive system to determine why the gearbox failed. A gearbox can be damaged by a gate that is dragging, hinges that are binding, incorrect arm geometry, missing or misadjusted physical stops, loose mounting hardware, impact damage, water intrusion, or an operator that is driving past its intended travel limits.
If the gearbox is noisy, leaking, slipping, or binding, also inspect the motor, output components, arm connection, mounting bracket, chassis, and gate movement. Installing a new gearbox without correcting a gate or linkage problem may lead to repeat failure.
Before Ordering, Confirm
- The required part number is MX4624-P or the approved related part number MX4624.
- The operator is a SwingSmart 535 or SwingSmart CNX model where the parts diagram lists this gearbox.
- The operator model and serial number match the parts diagram being used.
- The existing gearbox mounting, shaft/output arrangement, and arm hardware match the replacement.
- The repair requires the gearbox with oil, not a motor, controller, motor drive module, cover, reset switch, or arm hardware only.
- The package includes the expected oil-filled gearbox and any required hardware, or that additional hardware is ordered separately.
- The gate is not binding, sagging, overtraveling, or missing proper physical stops.
- The operator has not been modified or retrofitted with a different gearbox or drive arrangement.
Installation and Service Notes
- Disconnect and secure operator power before servicing the gearbox area.
- Support the gate and arm assembly so the gearbox is not loaded unexpectedly during removal.
- Do not force the gearbox into a chassis or output arrangement that does not match.
- Verify oil condition or factory-filled status before installation if required by the service procedure.
- Inspect output hardware, arm hardware, mounting bolts, and gate stops before returning the operator to service.
- After installation, verify smooth travel, correct limits, proper physical stop contact, and all required safety devices.
- Do not bypass entrapment protection, reset circuits, limits, or controller protections to test the operator.
Professional Advisory
Gearbox replacement on a swing gate operator should be performed by a qualified gate technician when the repair involves heavy gate movement, arm geometry, operator travel setup, gearbox alignment, physical stop adjustment, or unknown prior modifications. Do not bypass photo eyes, safety edges, inherent entrapment protection, limit controls, reset circuits, controller protections, or any required safety devices during testing.

Is MX4624-P the same as MX4624?
MX4624 appears to be the related base gearbox part number, while MX4624-P may indicate a packaged service version. Verify the current package contents and parts diagram before substituting one for the other.
Does MX4624-P come with oil?
Current listings describe MX4624-P and related MX4624 listings as a gearbox with oil. Verify the package condition and installation requirements before service.
Does this gearbox fit SwingSmart 535 or SwingSmart CNX?
Current listings use both SwingSmart 535 and SwingSmart CNX wording. Use this gearbox only where the operator model, serial number, and HySecurity parts diagram confirm MX4624-P or MX4624.
Is this gearbox the same as the SwingSmart DC gearbox?
No. SwingSmart DC gearbox references, such as MX002005, should not be treated as the same as MX4624-P unless HySecurity documentation confirms interchangeability.
What can cause a SwingSmart gearbox to fail?
Gearbox failure can be caused by normal wear, gate binding, incorrect arm geometry, missing or misadjusted physical stops, impact damage, loose hardware, water intrusion, motor or drive issues, or operating the gate outside the intended travel setup.
Should a technician install this gearbox?
Yes. A qualified gate technician is recommended because gearbox replacement can involve heavy gate movement, drive alignment, arm setup, physical stops, travel limits, and safety-critical operator operation.
