Additional Notes
- The front differential capacity across all listed Yamaha YFM Bruin 4x4 configurations is 0.35 liter, applying equally to both the YFM 35 and YFM 350 variants.
- A 0.35 liter capacity is a relatively small volume, consistent with a compact ATV front differential housing rather than a larger rear axle or transmission sump.
- The normal-use front differential change interval is set at 12 months for both the YFM 35 Bruin 4x4 (2005-2007) and the YFM 350 Bruin 4x4 (2004-2005), indicating a time-based service schedule rather than a mileage or hour-based one.
- An initial service change interval of 1 month is specified for the front differential on both the YFM 35 Bruin 4x4 and the YFM 350 Bruin 4x4, reflecting a break-in period during which new gear surfaces shed fine metallic particles into the fluid.
- The 0.35 liter capacity figure remains unchanged between the initial service and normal service rows for each configuration, meaning the fill volume is consistent regardless of which service interval applies.
- The YFM 350 Bruin 4x4 covers model years 2004-2005, while the YFM 35 Bruin 4x4 covers 2005-2007, with both sharing identical front differential capacity and interval specifications in the years where data is present.
