Key Features
- Correct Tension Rating — manufactured to Husqvarna's OEM spring specification, delivering the exact load and return force required for consistent throttle shaft operation
- Drop-In Replacement — engineered to match the original mounting position and shaft interface on the throttle assembly, allowing straightforward installation without modification
- Compatible with K650, K700, and K650CutnBreak Power Cutters — cross-reference part number 505316605 against your parts diagram to confirm fitment for your specific model
- Restored Throttle Response — a correctly tensioned throttle shaft spring ensures the throttle returns to idle promptly and consistently, maintaining smooth, controlled power delivery during cutting
- Operational Safety — a worn or broken throttle shaft spring can prevent the throttle from returning to idle, creating an uncontrolled runaway condition; replacing it promptly restores safe operator control
The throttle shaft spring provides the return tension that pulls the throttle mechanism back to the idle position when the operator releases the trigger. Without correct spring tension, the throttle may stick open or respond sluggishly, making it difficult to control cutting speed and creating a potential safety hazard. Replacing a fatigued or broken spring restores predictable, responsive throttle control and is an essential step in any throttle assembly service.
