Additional Notes

  • The front differential capacity across all listed Yamaha YFM Bruin 4x4 configurations is 0.35 liter, which represents a service fill volume typical of a compact ATV front differential housing.
  • Both the YFM 35 Bruin 4x4 (2006-2007) and the YFM 350 Bruin 4x4 (2004-2005) share an identical front differential capacity of 0.35 liter, indicating no variation in this specification between the two model year groups.
  • Under normal use conditions, the front differential fluid change interval is 12 months for both the YFM 35 Bruin 4x4 and the YFM 350 Bruin 4x4.
  • An initial service interval of 1 month is specified for the front differential on both configurations, which is a break-in service interval applied shortly after a unit enters operation to remove metal particles and contaminants generated during initial component wear-in.
  • The 1-month initial service interval paired with the 12-month normal interval means the front differential fluid on these models is serviced twice within the first year of operation before settling into the annual change schedule.
