JCB JS200–JS260 Series Common Problems This Manual Covers
JCB JS200-JS260 series main hydraulic functions become weak, slow, or intermittent during normal operation. p. 462
Test the main hydraulic pump operating pressure per the specifications on page 462. Inspect the system for contamination and replace the servo filter element as outlined on page 77. Clean the main control valve blocks if performance remains sluggish.
Manual Section: HydraulicsSlew performance drops significantly and the upper structure feels sluggish when rotating under load. p. 463
Measure the slew motor brake torque per the specification on page 463 for your model variant. Inspect the turntable bearing bolts and torque them to 525 Nm (387 lbf ft) as specified on page 118. Drain and inspect the swing gearbox oil.
Manual Section: Slew System FaultsEngine will not start or turns over slowly during early morning cold weather operation. p. 86
Check the battery terminals for corrosion and clean them thoroughly. Drain the engine oil and refill the system with exactly 23.5 litres of fresh oil for JS200-JS235 models on page 86. Tighten the new engine oil filter until the seal bites, plus one full turn.
Manual Section: Engine System FaultsTravel performance drops significantly and the tracks bind or hesitate when turning on soft ground. p. 163
Drain the track gearbox oil and check for internal metal contamination. Reinstall the track gearbox oil drain plug and tighten it to the torque specified on page 163. Refill with fresh fluid and test the travel pedal valve operation to ensure smooth movement.
Manual Section: Travel System FaultsFrequently Asked Questions
How do I reset the JCB JS200/JS220/JS240/JS260 service indicator or maintenance light?
To cancel the service indicator, press and hold the "SET" and "MODE" buttons on the EMS simultaneously for 20 seconds until "SERVICE OFF" is displayed. Then, press the "ACK" button, enter a four-digit dealer code using the "Up/Down" keys and "ACK" button, and finally press "SET" to save the code and extinguish the warning lamp. This procedure is detailed on page 346.
What do JCB JS200-series hydraulic or ECU error codes mean?
The manual provides tables detailing the meaning of various error codes for JCB JS200-series excavators. For instance, electrical fault code 104 signifies "HYD TMP The hydraulic temperature sensor is open-circuit." These codes are displayed on the EMS to indicate specific malfunctions within the engine or hydraulic systems, as listed in tables on page 385.
What are the torque specs for JCB JS200-series track adjuster, swing bearing, or engine mounting bolts?
For JS200-260 models, the torque specification for Engine (Engine Mount) bolts (M16) is 290 Nm (213 lbf ft) for tightening and 265 Nm (195 lbf ft) for checking. Turntable Bearing (Undercarriage) bolts (M20) require a tightening torque of 525 Nm (387 lbf ft) and a checking torque of 470 Nm (347 lbf ft). For the track adjuster check valve torque, refer to the torque settings tables in Section 1 of the manual.
What are the replacement specifications for Engine oil main filter element?
The Engine oil and filter should be sampled/changed at regular intervals, including 10, 50, 250, 500, 1000, 2000, 4000, and 5000 hours, as per the service schedules on page 76. When replacing the filter, smear the new filter's seal with engine oil, tighten it until the seal bites onto the filter housing, and then tighten a minimum of one more full turn.
