HySecurity MX3697-03, Bushings and Pins, 3 Hinges Replacement Kit
The HySecurity MX3697-03 kit provides replacement hinge wear hardware for three hinges on select HySecurity wedge barrier assemblies. It is intended for hinge pivot service where worn bushings or pins allow movement, looseness, chatter, or uneven wedge operation.
This kit is more than a loose hardware package. The bushing and pin fitment affects how the wedge plate tracks through its travel and how load is carried through the hinge assembly. Replacing only one worn component may not correct a hinge problem if the mating pin, bushing, or spring pin is also damaged.
Common replacement reasons include excessive hinge play, visible wear at the hinge pins, noisy wedge movement, a plate that does not track evenly, or hinge hardware damaged during impact repair.

Technician Note
Count the hinges before ordering. A three-hinge wedge and a four-hinge wedge can look similar from a distance, but the hardware kit quantity and part number are different.
Before Ordering
- Confirm the operator is a WedgeSmart-style wedge barrier, not a StrongArm crash arm
- Count the hinge assemblies on the barrier plate
- Check whether pins are worn or whether a bushing-only kit is sufficient
- Inspect hinge brackets for elongation or impact damage before installing new pins
- Support the wedge plate properly during hinge service
Professional Advisory
Hinge service on a wedge barrier involves heavy hardware and pinch points. Use proper support and have a qualified technician perform the repair when the barrier plate is damaged, binding, or difficult to move.
Questions & Answers
What comes in the MX3697-03 kit?
The MX3697-03 kit is identified as a replacement kit with bushings, pins, and spring pins for three hinges.
Which operators commonly use MX3697-03?
It is commonly associated with HySecurity WedgeSmart hinge service, especially three-hinge 9 ft and 10 ft WedgeSmart models.
Is MX3697-03 for a four-hinge wedge?
No. Four-hinge wedge assemblies commonly require the MX3697-04 kit instead of the three-hinge MX3697-03 kit.
When should hinge bushings and pins be replaced?
They should be inspected for replacement when the wedge has hinge play, noisy movement, uneven travel, visible pin wear, or damage after a vehicle impact.
Can I replace only the bushings instead of this kit?
If the pins are still within specification, a bushing-only kit such as MX3696-03 may be relevant, but the parts diagram and hinge condition should decide the correct repair.
