H137 Chainsaw Clutch Assembly Garden Logging Replacement Part

This clutch is specially designed for H137 chainsaws. Thick cast iron clutch pads feature high density and great wear resistance against continuous high-speed friction, maintaining stable power transmission after long working hours. The two heat-treated thick steel springs have strong anti-fatigue capacity, keeping steady elasticity after repeated expansion and contraction. The pads expand to engage the chain at high rotation speed and retract to cut power at idle for easy operation. Precision machining ensures standard central hole size for easy installation with common tools. It performs reliably under dusty and high-vibration conditions in forest logging and yard trimming, resisting spring detachment and loose pads. Compatible with all H137 chainsaws, it meets daily maintenance demands and supports long continuous operation effectively.
