JCB TM200, TM270, TM300 Common Problems This Manual Covers
JCB TM300 hydraulic attachment control is erratic and only works in short bursts before stopping. p. 277
Inspect the Smooth Ride System pressure switch as detailed on page 277 if the attachment system will not activate. Replace the faulty switch as necessary. When reassembling the auxiliary section of the loader control valve, tighten the shut off plug assembly to exactly 65 Nm.
Manual Section: Hydraulics - Smooth Ride System (SRS) - Fault FindingEngine runs hot, loses power under heavy load, or shows abnormal valve train noise. p. 548
Measure the valve clearances when the engine is completely cold. Adjust the TM200 inlet clearance to 0.20 mm (0.008 in) as specified on page 548. Set the exhaust valves to 0.45 mm (0.018 in). Check the cooling system for restrictions and verify coolant levels before restarting the loader.
Manual Section: EngineLoader loses transmission drive power or implements become weak and jerky under heavy load. p. 467
Test mainline and converter pressures following the powershift transmission flow testing procedures. Drain the fluid and remove the suction strainer. Clean the housing thoroughly and install the suction strainer using a new gasket. Tighten the strainer bolts to exactly 10 Nm as noted on page 467.
Manual Section: TransmissionPowershift transmission leaks fluid from the output shaft and fails to maintain internal operating pressure. p. 480
Remove the old output shaft oil seal and clean the mounting bore. Pack grease securely between the lips of the new seal before pressing it into place. Tighten the powershift transmission drain plug to 203 Nm as shown on page 480 to prevent further fluid loss during operation.
Manual Section: TransmissionFrequently Asked Questions
What do the error codes mean on a JCB TM200/TM270/TM300?
For the Load Moment Indicator (LMI) on the TM300, Fault Code 1 indicates a transducer signal fault, Fault Code 2 means calibration is out of range, Fault Code 3 signifies calibration is required, Fault Code 4 points to a display unit fault, and Fault Code 5 indicates low battery voltage (below 9 volts). These codes help diagnose issues with the LMI system.
What are the torque specs for JCB TM200/TM270/TM300 wheel nuts?
The correct torque specification for both front and rear wheel nuts on the JCB TM200, TM270, and TM300 models is 680 Nm (500 lbf ft). It is recommended to check these torques every two hours on new machines or whenever a wheel has been removed, until they remain correct.
What are the torque specs for JCB TM200/TM270/TM300 boom pins?
For boom shim adjustment, the M10 TUF Lock with plain washers should be tightened to 98 Nm (72 lbf ft). This specification is relevant for bolts associated with the boom structure, although not explicitly for 'boom pins' as a general category.
What are the replacement specifications for hydraulic filters?
For the TM200, TM270, and TM300 models, the hydraulic filter's filtration size is 25 microns. The bypass pressure for these filters is 1.05 bar (1.07 kgf/cm² or 15 lbf/in²).
