Additional Notes

  • The Yamaha YFM 350 Wolverine 4x4 front differential carries a dry fill capacity of 0.2 liter, while the service fill drops to 0.18 liter. The difference between dry fill and service fill reflects residual fluid that remains in the housing during a routine drain, meaning a full overhaul or assembly from dry requires slightly more fluid than a standard fluid change.
  • For the YFM 350 Wolverine 4x4 covering model years 1998-2005, the front differential fluid interval under normal use is 12 months. The initial service interval, however, is set at just 1 month, a break-in change intended to flush metal particles generated during the early wear-in period of new components.
  • The YFM 45 Wolverine 4x4 for 2006-2008 lists a single front differential capacity figure of 0.35 liter with no separate dry fill and service fill distinction, unlike the 350 variant which specifies both values.
  • The 2006-2008 YFM 45 Wolverine 4x4 shares the same interval structure as the 350 model, with a 12-month normal change interval and a 1-month initial service change tied to the same 0.35-liter front differential capacity.
  • The 2010 YFM 45 Wolverine 4x4 front differential retains the 0.35-liter capacity but introduces a multi-condition normal service interval expressed as 3,200 miles, 12 months, or 320 hours, whichever comes first. Earlier model years list only a calendar-based interval, making the 2010 specification notably more detailed in how service timing is defined.
  • Under initial service conditions, the 2010 YFM 45 Wolverine 4x4 front differential change is due at 200 miles, 1 month, or 20 hours. Each of those three thresholds corresponds to roughly one-sixteenth of the respective normal-use limit, reflecting how tightly the break-in service window is defined relative to ongoing maintenance.
