Additional Notes

  • The front differential on the Yamaha YFB 250 Timberwolf 4x4 carries a dry fill capacity of 0.7 liter, which represents the total volume the housing holds when completely empty, such as after a rebuild or component replacement.
  • The service fill capacity of 0.67 liter is lower than the dry fill figure, reflecting the residual fluid that remains in the differential housing during a standard drain and refill procedure.
  • Under normal use conditions, the front differential fluid change interval is set at 12 months for the 1998-2001 YFB 250 Timberwolf 4x4.
  • An initial service interval of 1 month applies to the front differential, with the same dry fill and service fill capacities of 0.7 liter and 0.67 liter respectively, indicating an early break-in fluid change is specified separately from the standard annual schedule.
