The Honda 31112-895-000 Fan is a genuine OEM Fan designed for Honda EB3000, EB4000, EM3000, EM4000, EMS4000, EMS4500, EV4000, and EW170 generators and welder generators. As a direct Honda OEM part, it is manufactured to the same specification as the original component, ensuring the cooling airflow your generator depends on is fully restored. Verify your unit's serial number against the fitment table to confirm this Fan is the correct match for your specific production run before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Fan meets the original design specification for consistent airflow delivery across the generator's cooling system.
- Broad Generator Fitment — compatible with Honda EB3000, EB4000, EM3000, EM4000, EMS4000, EMS4500, EV4000, and EW170 generators and welder generators, including the EW170 welder generator.
- Serial Number Verification Recommended — Honda supersedes parts at serial number breaks; confirm your unit's serial number against the compatibility table to ensure the correct Fan for your machine.
- Cooling Performance — a worn or damaged fan reduces airflow across the alternator and engine, leading to overheating and reduced output; replacing it restores proper thermal management.
The fan in a Honda generator draws cooling air across the alternator windings and through the generator enclosure, preventing heat buildup that would otherwise degrade output quality and shorten component life. On conventional generators such as the EB and EM series, the fan is driven mechanically and must move sufficient volume of air to keep the alternator and engine running within their designed temperature range. When the fan cracks, chips, or loses a blade, airflow drops sharply, and the generator can overheat under load — making timely replacement with part number 31112-895-000 essential to keeping the unit running at rated capacity.
