JCB Fastrac 125 Series

Clutch fluid capacity & service interval

JCB Fastrac 125 Series clutch fluid capacity is 0,5 liter. Service intervals include a check at 50 hours and a change at 2000 hours or 24 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 125 Series carries a clutch fluid capacity of 0.5 liter across both serial number ranges covered in the 1991-1997 production span. A 0.5-liter figure is characteristic of a service fill volume in a hydraulic clutch system, representing the fluid held within the reservoir and lines rather than a full overhaul quantity.
  • Both configurations, those up to serial number 636.000 and those from 636.001 onward, share an identical check interval of every 50 hours. In hydraulic clutch applications, a 50-hour check interval is relatively frequent and reflects the importance of monitoring fluid level and condition before significant degradation or leakage goes undetected.
  • The change interval is specified at 2000 hours or 24 months, whichever comes first, under normal use conditions. The dual-trigger structure means a machine with low annual operating hours would still require a fluid change at the 24-month mark regardless of the hour reading.
  • The serial number split between the two rows, at 636.000 and 636.001, represents a production break point rather than a specification difference, as both ranges carry the same capacity, check interval, and change interval values.
