Additional Notes

  • The JCB Fastrac 150 Series carries two distinct manual transmission fluid capacities depending on serial number: units up to serial 636.000 require 10 liters, while units from serial 636.001 onward require 38 liters.
  • The 38-liter capacity on the higher serial number variant reflects a combined fill covering the manual transmission, range gearbox, and PTO gearbox as a single shared sump, rather than separate individual fills.
  • The 10-liter figure on pre-636.001 units covers the transmission only, indicating a more limited or separate gearbox arrangement compared to the later configuration.
  • Both serial number variants share identical fluid check intervals of every 10 hours of operation under normal use conditions.
  • The change interval for both configurations is 1000 hours or 12 months under normal use, whichever comes first, meaning calendar time can trigger a service even before the hour threshold is reached.
  • The 10-hour check interval is notably short relative to the 1000-hour change interval, reflecting the importance of monitoring fluid level frequently in the early stages of operation and throughout regular use.
