JCB Fastrac 155 Series

Transfer case fluid capacity & service interval

JCB Fastrac 155 Series transfer case fluid capacity is 3 liters. Service intervals include checking every 50 hours and changing every 1000 hours or 12 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The JCB Fastrac 155 Series carries a transfer case fluid capacity of 3 liters across both serial number ranges covered in the 1991-1997 production span, applying to the transferbox/p.t.o., front assembly in each case.
  • A 3-liter fill is a relatively modest volume, consistent with a dedicated transfer and power take-off unit rather than a combined transmission or axle housing, where capacities would typically run considerably higher.
  • The check interval is set at 50 hours under normal use conditions, reflecting the relatively frequent monitoring expected of a working agricultural machine where fluid contamination or minor leakage can develop quickly during field operation.
  • The change interval is specified at 1000 hours or 12 months, whichever comes first under normal use conditions, meaning calendar time alone can trigger a fluid change even when hour accumulation has not reached the threshold.
  • Serial number boundary 636.000 separates the two listed configurations, with units up to and including 636.000 forming one group and units from 636.001 onward forming another, though both groups share identical capacity and interval specifications for the transferbox/p.t.o., front.
