Additional Notes

  • The JCB Fastrac 135 Series carries a transfer case fluid capacity of 3 liters across both serial number ranges, covering units up to serial number 636.000 and those from 636.001 onward, with both configurations sharing identical service specifications.
  • A 3-liter capacity in a transfer case of this class is a moderate fill volume, consistent with a compact agricultural transfer box rather than a heavy-duty multi-range unit, reflecting the Fastrac 135's role as a lighter high-speed tractor platform.
  • The fluid check interval is set at 50 hours under normal use conditions, which in agricultural equipment terms typically falls within the first few weeks of seasonal operation, making frequent early monitoring a built-in part of the service schedule.
  • The fluid change interval is specified at 1000 hours or 12 months, whichever comes first under normal use conditions, meaning calendar time alone can trigger a required change even when hour accumulation remains low.
  • Both serial number ranges, units up to 636.000 and units from 636.001 onward, share the same 3-liter capacity and the same 50-hour check and 1000-hour/12-month change intervals, indicating no revision to transfer case service requirements was introduced at the 636.001 serial number break point.
  • The note identifying the system as a transferbox/p.t.o., front unit indicates the fluid serves a combined transfer case and front power take-off assembly, meaning the 3-liter fill supports both functions simultaneously within a single shared sump.
