JCB 2CX Backhoe Loader, 210S, 210S U.S.A. build machine, 2CX Common Problems This Manual Covers
JCB 2CX backhoe loader engine runs fine but machine will not move forward or reverse p. 81
Inspect the charging system on page 81. Remove the alternator and check brush length. Replace the brushes if they measure less than 8 mm (0.3 in). Verify the battery cranking performance reaches 410 Amps to 1.4 V.P.C. as listed on page 76 to restore drive functions.
Manual Section: ElectricsEngine fires up but immediately dies or fails to stay running under normal operating load p. 62
Check the battery electrolyte level as detailed on page 62. Fill with distilled water until the fluid reaches 6 mm (1/4 in) above the plates. Inspect the alternator drive belt for slippage and adjust the deflection to approximately 10 mm (3/8 in) per page 56 guidelines.
Manual Section: Routine MaintenanceComplete loss of power immediately after loading the bucket or tipping material into a truck p. 342
Test the fuel delivery system and verify the engine idling speed maintains a steady 750 rev/min as specified on page 342. Drain the tank and refill with clean diesel, noting the standard 2CX Backhoe Loader fuel capacity is 64 Litres (14 UK Gal) on page 34.
Manual Section: EngineHydraulic boom functions operate normally but syncro shuttle drive and transport functions work only intermittently p. 91
Test the main relief valve operating pressure on page 91 to confirm it holds 220 bar. If hydraulic pressure is correct, follow the transmission troubleshooting procedures. Clean all major wiring harness grounds and battery terminals to fix electrical voltage drops affecting control solenoids.
