Suitable for Husqvarna 450 and 445 chainsaws, including clutch springs, clutch extension springs, clutch brake springs and small springs for chainsaw accessories.

Although small, the clutch spring is an essential component of a chainsaw's clutch system. It returns the chain lock to its neutral position when idling, preventing the chain from spinning freely. During acceleration, it provides sufficient elasticity to ensure smooth engagement of the pawl with the clutch drum and optimal power transmission. If your Husqvarna 450 or 445 chainsaw exhibits the following problems, the clutch spring likely needs replacing: the chain spins freely at idle, acceleration is weak and jerky, throttle response is delayed, or unusual noises are heard from the clutch area. This product is specifically designed for Husqvarna 450 and 445 chainsaws and is precision-machined from high-quality spring steel. The spring undergoes rigorous heat treatment and fatigue testing to ensure lasting and stable elasticity and prevent loosening or breakage. Its installation dimensions conform to the original specifications. Simply replacing the worn or damaged spring restores the clutch to its normal function. It is recommended to check the chain lock for wear when replacing the spring. If it is heavily worn, replacing this part is recommended to ensure the clutch system functions correctly. This high-quality replacement part offers a cost-effective repair solution and restores the smooth power transmission of your chainsaw.
