The Honda 52218-740-921 Knob Bolt Spring is a genuine OEM component designed for the HP400 power carrier. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring proper function of the knob bolt mechanism it serves. Verify your unit's serial number against the fitment table before ordering to confirm this is the correct part for your HP400.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this spring matches the original specification for the HP400 power carrier, with no substitution or compromise.
- Exact Replacement — designed to drop into the existing knob bolt assembly without modification, restoring the intended tension and function.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so check your HP400's serial number against the fitment table to confirm part number 52218-740-921 is correct for your unit.
- Restore Positive Engagement — a fatigued or broken spring causes the knob bolt to lose consistent tension, leading to loose or unreliable locking; this replacement brings that engagement back to spec.
The Knob Bolt Spring provides the return tension that keeps the knob bolt properly seated and engaged on the HP400 power carrier. Without adequate spring tension, the bolt can work loose during operation, allowing components to shift or disengage unexpectedly. Replacing a worn or broken spring restores the firm, consistent clamping action the HP400 relies on for secure, stable use in the field.
