Replacement mount buffer for compatible chainsaw models. This component isolates vibration between the engine and the body, helping maintain a secure fit and consistent operation when the original buffer is worn or damaged. Key benefits Restores stable mounting and reduces vibration transfer to the handle and housing. Designed for direct replacement on listed models for a precise fit and straightforward installation. Durable construction maintains damping performance under normal use. Simple swap using basic hand tools reduces downtime during maintenance. Important attributes Function: vibration isolation and secure enginetoframe mounting. Compatibility: fits models 029, 039, MS290, MS310, MS390, 021, 023, 025, MS210, MS230, MS250 chainsaws. Size: replacement part manufactured to match standard dimensions for the compatible models. Material: engineered elastomeric compound for resilient damping under load. Performance: restores factorystyle buffering to reduce vibration transmission and maintain alignment of engine and housing. Typical applications Routine maintenance: a hardened or cracked mount buffer during scheduled service to restore normal vibration control. after impact or wear: install when vibration increases or mounting feels loose following heavy use or accidental shock. Refurbishing a used saw: fit mount buffers when preparing a used chainsaw for resale or to reliable operation. Installation notes Inspect mounting bolts and surrounding components and any worn hardware. Tighten to the specified torque for the model being serviced. If vibration continues after replacement, check other mounts and accessory fittings for wear. This replacement mount buffer provides the correct fit for the listed chainsaw models and is intended for maintenance and tasks where restoring proper vibration isolation and mounting alignment is required.
