Restore factory feel and reliable operation to your equipment with a chain tensioner bolt built to spec and ready for service. Verified for Echo applications. Cross-references factory part number V203000110. Watch for these symptoms when the existing part starts to fail: missing washers, corroded heads, or torque that won't hold. Reinforced where the factory part tends to fatigue — built to outlast the stock part under the same operating cycle. Before install, photograph the existing layout, confirm the existing part number on your worn unit, and match physical dimensions and mounting pattern. Follow your service manual sequence and torque values for a clean, long-lasting repair. Save the dealer trip and the dealer markup without sacrificing fit or build quality. Engineered for direct fit with factory-spec dimensions — verify your part number and order with confidence.
