JCB JS115–JS360 Series Common Problems This Manual Covers
JCB JS360 engine performance loss, fuel starvation, or hard starting under heavy load p. 510
Inspect the fuel system for contamination if hard starting occurs. Drain and flush the fuel tank as detailed on page 91. Replace primary and main filters. Check engine valve clearance on page 510, ensuring both inlet and exhaust measure exactly 0.40 mm.
Manual Section: Engine Fault Finding - Engine ComponentsHydraulic sluggishness, weak digging power, or slow and erratic implement response during operation p. 372
Check the main control valve and relief valve for contamination. Inspect the hydraulic system components for leaks. Retorque the main control valve to frame bolts to the torque value specified on page 372. Verify the engine oil level matches the 38 litres capacity shown on page 92.
Manual Section: Hydraulic SystemLoose or missing bolts, rattling, or undercarriage component loosening after initial run-in period p. 103
Verify all critical fasteners after the initial run-in period. Torque the cab mounted FOPS mounting bolts to the value specified on page 103. Inspect the undercarriage and adjust track tension to the measurement specified on page 164.
Manual Section: Bolt and Nut Torque SpecificationsTravel motor not running, low motor speed, or abnormal noise while tracking
Drain and inspect the track motor fluid for metal wear particles. Refill the reduction gear with fresh oil to the quantity specified on page 412. Review the troubleshooting procedures to diagnose low motor speed, abnormal noise, or pressure variation due to cavitation.
Manual Section: Transmission Fault Finding - Traction MotorFrequently Asked Questions
Why is my JCB excavator showing an error code after startup?
For the Automatic Temperature Control (ATC) system, an error code displayed instantly after startup indicates a wiring error. If the error code appears after one minute, it suggests a system error.
What does the JCB JS series warning light or buzzer mean?
The meaning of warning lights and buzzers varies depending on the specific error. For engine-related issues, the 'Engine Error Codes' table on page K-3 provides details on whether an engine fault LED, caution LED, or buzzer (for 1.5 seconds) is activated, along with the error code display and message.
How to reset JCB JS115 error code
For errors within the Automatic Temperature Control (ATC) system, a battery reset may be required to clear the error after the necessary repair has been completed.
What are the replacement specifications for fuel filters?
The Primary Fuel Filter/Sedimenter should be changed every 250 hours, and the Main Fuel Filter/Sedimenter should be changed every 500 hours. The Fuel Pump Filter Element also requires changing every 250 hours.
