JCB 525–535 Common Problems This Manual Covers
JCB 525-67 front-rear axle indication lost with flashing warning lights on the dashboard.
Inspect the wheel speed sensors and wiring loom underneath the axle box sections. Check the dashboard indicator meanings. Verify the front tyre pressure is exactly 3.7 Bar (54 lbf/in²) as uneven rolling diameter can trigger sensor faults.
Manual Section: OperationIntermittent joystick control function or unexpected loss of machine control inputs during operation.
Verify the electrical connectors and wiring loom in the operator controls layout. Inspect the control-stick switches for poor contact. Check the transmission oil filter, ensuring it was replaced at the 250 Hr service interval to maintain servo pressure.
Manual Section: OperationEngine oil pressure warning light flashing on the dashboard immediately after morning startup. p. 50
Check the engine oil level using the dipstick before starting the machine (page 116). Fill the system to the specified 10 Litres (2.2 Gal) capacity (page 136) if low. Inspect the engine bonnet and cover area for visible fluid leaks before checking the dashboard warning indicator meaning (page 50).
Manual Section: MaintenanceStrange rattling noise from the cab roof structure when driving over rough terrain. p. 103
