Troubleshooting & FAQ
How do I know if this air filter fits my specific Yanmar engine?
This filter fits a wide range of Yanmar GM and YM series engines. The best way to confirm is by checking your engine's model number against the compatibility table on this page. You can also verify by cross-referencing your old filter's part number with the numbers listed in our Part Number Matrix.
What is the main function of this filter element?
Its primary purpose is to filter intake air, preventing dust, salt, and other airborne particles from entering the engine. It also serves a secondary function of suppressing engine intake noise.
What are the signs that my air filter needs to be replaced?
Common symptoms of a clogged air filter include decreased engine performance, increased black smoke from the exhaust, and higher fuel consumption. A visual inspection showing a dark, dirty, or damaged foam element is also a clear indicator for replacement.
How often should I replace this filter?
Replacement intervals depend on your engine's operating environment. In dusty or salty conditions, more frequent checks are needed. As a general guideline, inspect the filter during every oil change and replace it at least once per season or as recommended in your Yanmar service manual.
