Additional Notes

  • The JCB Fastrac 1000 Series manual transmission fluid capacity is 38 liters across all four variants covered by these specifications, namely the 1115, 1115S, 1125, and 1135 built between 1994-1998.
  • A 38-liter fill volume reflects a combined service fill rather than a single isolated gearbox, which aligns with the noted scope of each row covering the manual transmission, range gearbox, and PTO gearbox as a shared fluid system.
  • The fluid level check interval is set at every 10 operating hours under normal use conditions, indicating a relatively frequent monitoring requirement given the large shared fluid volume across multiple gear assemblies.
  • The drain and refill interval is specified at 1000 hours or 12 months under normal use conditions, whichever comes first, meaning calendar time can trigger a fluid change even when the hourly threshold has not been reached.
  • All four Fastrac variants in the 1994-1998 production range share identical capacity and interval figures, with no differentiation in fluid service requirements between the base 1115, the 1115S, the 1125, or the 1135 configurations.
