JCB 2CX & variants Common Problems This Manual Covers
JCB 2CX backhoe and loader functions are weak or intermittently stop working under heavy loads p. 170
Test main relief valve pressure as outlined on page 170. Verify the pressure reads 240 bar for 2DX and 2CX machines from serial 658961. If readings fall below this spec, inspect the relief valve for worn O-rings or broken springs. Replace damaged components and retest the circuit.
Manual Section: HydraulicsFoot brake pedal feels spongy or requires excessive force to stop the machine p. 360
Check the brake system pressure testing procedures on page 360. Connect a gauge and verify the brakes accumulator pressure holds steady at 25 bar. If the pressure drops rapidly, bleed the brake circuit to remove trapped air or replace the accumulator charge valve seals.
Manual Section: BrakesSteering wheel becomes heavy or erratic when maneuvering at low engine speeds p. 171
Install a pressure gauge at the steering circuit test port. Verify the steering relief valve operating pressure reaches exactly 139 bar as specified on page 171. If pressure is low, inspect the steering alignment valve and steer ram for internal bypass leakage.
Manual Section: HydraulicsRepeated fluid leakage observed around the axle hubs and drive shaft bearing carriers p. 358
Remove the hub and inspect the driveshaft bearing carrier combination seal. Press the new seal level with the wheel bearing carrier face Z for a 25 to 26mm dimension as shown on page 358. Torque all 3/4-inch UNF Grade S retaining bolts to 407 Nm during reassembly.
Manual Section: TransmissionEngine runs rough, loses power, and the air cleaner warning light illuminates on the dash p. 381
Inspect the intake system for blockages before replacing the filter element. Measure the air cleaner maximum restriction according to page 381. Replace the primary element if the vacuum reading exceeds 559mm (22 in) H20 for North American machines built from serial number 762080.
Manual Section: EngineFrequently Asked Questions
What is the torque spec for JCB 2CX wheel nuts?
The torque specification for road wheel retaining nuts (Item B) is 680 Nm (69 kgf m, 500 lbf ft). It is recommended to check the tightness of wheel nuts every day for the first week when the machine is new, and thereafter every 50 hours.
What are the replacement specifications for Hydraulic filters?
When changing the hydraulic filter element, ensure to clean the mating faces and smear the seal D of the new element with hydraulic oil. Screw the new filter element on clockwise into the filter head until the gasket makes contact, then tighten it a further half a turn. The filter element should be changed at 100 Hr and 500 Hr intervals.
What are the replacement specifications for Fuel filters?
To renew the fuel filter element, first hold bowl B and unscrew bolt C to remove the bowl and filter element D, then wash the bowl in clean fuel. Inspect and renew sealing rings E, F, G, and H if damaged. Finally, fit the new element D, sealing rings, and bowl B, then tighten bolt C. The fuel filter should be changed at 100 Hr and 500 Hr intervals.
How do you fix JCB 2CX backhoe and loader functions are weak or intermittently stop working under heavy loads?
Test main relief valve pressure as outlined on page 170. Verify the pressure reads 240 bar for 2DX and 2CX machines from serial 658961. If readings fall below this spec, inspect the relief valve for worn O-rings or broken springs. Replace damaged components and retest the circuit.
