JCB Fastrac 1000 Series

Transfer case fluid capacity & service interval

JCB Fastrac 1000 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 4 configurations.

Additional Notes

  • All four variants of the JCB Fastrac 1000 Series covered here — the 1115, 1115S, 1125, and 1135 — share an identical transfer case fluid capacity of 3 liters, applying specifically to the transferbox/p.t.o., front assembly.
  • A 3-liter capacity in a transfer case of this type is a relatively modest fill volume, consistent with a compact front power take-off and transfer assembly rather than a large combined drivetrain sump.
  • The fluid check interval across all four variants is set at 50 hours of operation under normal use conditions, reflecting the relatively frequent monitoring expected in agricultural machinery operating environments.
  • The fluid change interval is specified at 1000 hours or 12 months under normal use, whichever comes first, meaning calendar time can trigger a service requirement even when hour accumulation is low.
  • The 1115S shares the same transferbox/p.t.o., front capacity and service intervals as the standard 1115, indicating no specification difference between those two variants for the transfer case system.
  • The ratio between the check interval (50 hours) and the change interval (1000 hours) means a fluid level inspection is due approximately 20 times before a full fluid change is required under normal use conditions.
