CNLJPHFHO

Model Compatibility: Precisely 56mm big bore fits 064, 066, MS640, MS650, MS660 chainsaw models. Replaces OEM 1122 020 1211, 1122 020 1209 to fix difficult starting, power loss, excessive exhaust smoke, and oil leakage caused by worn cylinder walls, damaged piston rings, or blown gaskets during heavy tree felling, logging, storm cleanup, and professional forestry operations. Big Bore Power Boost: Increases engine displacement for +15% more power and +20% torque compared to stock 52mm/54mm cylinders, ideal for cutting through dense hardwood, large diameter trees, and frozen logs. Pop-up piston design enhances compression ratio for faster acceleration and improved cutting efficiency in professional logging and land clearing projects. Sealing : Precision-machined Nikasil or Titanikel plated cylinder surface with matched high-tension piston rings and high-density gaskets creates airtight seals, eliminating compression loss and fuel waste—critical for maintaining consistent power output during extended cutting sessions in wet forests or dusty logging sites. Reinforced piston skirt prevents scoring and deformation, ensuring long-term sealing integrity under heavy load. Durable Construction: High-strength forged alloy cylinder withstands extreme temperatures (up to 400°C) and intense mechanical vibration, while heat-treated piston resists wear from high-speed operation. Corrosion-resistant surface coating protects against wood dust, moisture, and outdoor elements, ensuring reliable in harsh forestry environments and frequent professional use. Complete Kit Convenience: Includes cylinder, pop-up piston, rings, wrist pin, circlips, and gaskets for full top-end rebuild. Standard dimensions match original specifications, enabling drop-in replacement without modifications. Ideal for professional loggers, arborists, and forestry workers needing maximum power for demanding cutting tasks., Manufacturer: CNLJPHFHO
