Additional Notes

  • The front differential on the Valtra (Valmet) 04 Series carries a capacity of 3.5 liters across both the 604-4 (D33C) and 604T-4 (TD33C) configurations for 1982-1985, indicating a service fill volume rather than a full overhaul quantity.
  • Both the naturally aspirated 604-4 and the turbocharged 604T-4 share an identical front differential change interval of 800 hours or 12 months under normal use conditions, whichever comes first.
  • A notable difference exists in the check interval between the two configurations. The 604-4 with the D33C engine calls for a fluid level check every 400 hours, while the 604T-4 with the TD33C engine specifies a check interval of just 10 hours under the same normal use condition.
  • The 10-hour check interval on the 604T-4 front differential reflects a significantly more frequent monitoring requirement compared to the 604-4, despite both units sharing the same 3.5-liter capacity and annual change schedule.
