JCB JS200–JS260 Series Common Problems This Manual Covers
JCB JS200 JS220 excavator complete loss of hydraulic power or weak boom and lift movement p. 526
Test the main relief valve pressure using the diagnostic ports. Verify the MRV standard pressure reaches exactly 343 bar (4975 lb/in2) as detailed on page 526. If the reading drops below this threshold, inspect the main hydraulic pump seals or replace the relief valve entirely.
Manual Section: Hydraulics Fault Finding (Components & Tests)Unusual grinding noise from the track drive assembly during travel or pivot maneuvers p. 782
Inspect the final drive and track motor assemblies for excessive wear. Check the drive sprocket fastening bolts and torque them to 267-312 Nm as specified on page 782. Drain the travel motor oil and check for metal shavings indicating severe internal gear damage.
Manual Section: Transmission Fault FindingEngine overheating under heavy load with no visible coolant leaks or steam p. 73
Clean the radiator fins and inspect the radiator cap operation as outlined on page 73. Check the thermostat and replace it immediately if it fails to open at the correct temperature. Verify engine valve clearances are within specification by consulting the Engine Technical Data section.
Manual Section: Engine and Related Area TroubleshootingRecurring failure to start or erratic engine operation in cold weather conditions p. 80
Verify the fuel system is free of contamination and bleed the injector lines. Check that the fuel tank is adequately filled, referring to page 80 for capacities, to prevent drawing air. Repair or replace the fuel injection pump if pressure remains low.
