Overview
An official step-by-step walkthrough from Yanmar covering the complete oil change procedure for the YT3 series, including service intervals (50-hour initial, then every 200 hours), exact tools and socket sizes, filter installation details, and model-specific oil capacities (8 quarts for the YT359, 7 for the YT347). It closes with resetting the panel meter service interval. Most useful as a straightforward reference for first-time YT3 owners doing this job themselves.
