Additional Notes

  • The Steyr 8300 series transmission and hydrostatic/hydraulic system shares a unified fluid capacity of 58 liters across all listed variants, including the 83 TK, 83 TK Intercooler, 8300, 8300a, 8320, and 8320a. A capacity at this scale reflects a combined sump serving both the transmission and the hydrostatic/hydraulic circuit rather than a standalone gearbox fill.
  • The 58-liter figure applies consistently across the 1985-1988 and 1988-1994 production periods for every variant in the specifications, indicating no revision to system volume occurred between those two periods.
  • The check interval is set at 500 hours under normal use conditions across all variants. In hour-based service schedules typical of agricultural and heavy equipment, a 500-hour check interval represents a mid-cycle inspection point rather than a full fluid replacement event.
  • The fluid change interval is specified at 1000 hours or 12 months, whichever comes first, under normal use conditions. The dual-trigger format means calendar time can mandate a change even when the hourly threshold has not been reached, which is relevant for equipment operated at low annual hours.
  • The Intercooler variants of the 83 TK carry identical transmission and hydrostatic/hydraulic fluid specifications to the non-intercooler 83 TK across both the 1985-1988 and 1988-1994 periods. The intercooler designation refers to the engine induction system and does not alter the fluid system requirements reflected here.
  • The 8320 and 8320a variants share the same 58-liter capacity and service intervals as the 8300 and 8300a, despite the numeric designation difference. Both pairs follow the same 500-hour check and 1000-hour/12-month change schedule under normal conditions.
  • The "a" suffix variants, such as the 8300a and 8320a, carry no differentiation in fluid capacity or service intervals relative to their non-suffixed counterparts in either the 1985-1988 or 1988-1994 specifications.
