Additional Notes

  • The JCB Fastrac 3155 and 3185 share an identical transfer case fluid capacity of 3 liters for the transferbox/p.t.o., front assembly, indicating a service fill volume rather than a full overhaul drain-and-refill figure.
  • The 1000-hour or 12-month change interval on both the Fastrac 3155 and 3185 applies under normal use conditions, meaning whichever threshold arrives first governs the service timing.
  • A 3-liter capacity in a transfer case of this type is a relatively modest volume, consistent with a compact front power take-off and transferbox unit rather than a large-format drivetrain assembly.
