The Honda 51521-715-000 Lock Spring is a genuine OEM component designed for F28 and F400 tillers. Sourced directly from Honda, this part is manufactured to the same specification as the original, ensuring a proper fit in your machine. If your current spring has lost tension, broken, or become deformed, this direct Honda replacement is the correct part to restore proper operation. Always verify your tiller's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, manufactured to the original specification for the Lock Spring position in F28 and F400 tillers.
- Direct Replacement — engineered to install in place of the original without modification, restoring the spring's designed tension and retention function.
- Correct Fitment for F28 and F400 Tillers — confirm your model and serial number against the fitment table, as Honda updates parts at production breaks and fitment can vary within a model range.
- Restore Positive Locking Action — a fatigued or broken lock spring can allow controls or mechanisms to move out of position during operation; this replacement brings the assembly back to its original holding force.
A lock spring provides the retaining tension that holds a lever, collar, or control component in its intended position during machine operation. In the context of F28 and F400 tillers, this type of spring resists unwanted movement caused by vibration and operating loads, keeping the relevant assembly seated and engaged as designed. When the spring weakens or breaks, the connected component may slip, rattle, or fail to stay in position, which affects operator control and the tiller's consistent performance.
