JCB 457 Common Problems This Manual Covers
JCB 457 wheel loader no start or hard start after preheat and ignition sequence p. 134
Check the battery isolator and ensure the transmission is in neutral. Verify the engine oil and other fluid levels are within range per the specifications in the Routine Maintenance section. Inspect the fuses and clear any active warning lights before attempting another start.
Manual Section: Routine MaintenanceHydraulic leak, kinks, or damaged hose and fitting visible during daily machine walkaround inspection p. 200
Replace damaged hoses before you use the machine again. Verify replacement hoses match the exact size and standard of the originals. Check the wheel nut torque while inspecting the area, tightening front nuts to 600 Nm as specified on page 200.
Manual Section: Optional AttachmentsPrimary fuse repeatedly blows resulting in dead heated mirrors and heated seat p. 169
Inspect the wiring harness for shorts near the cab seat and mirror mounts. Replace the blown PF1 primary fuse with a new 60A fuse as detailed on page 169. Test the circuit by turning on the ignition and activating the mirror heaters.
Manual Section: Routine MaintenanceWarning lights do not go out after engine start or coolant temperature runs high p. 177
Inspect the radiator and check the coolant level in the sight glass. Drain and refill the system with 40 L of coolant if degraded, checking page 134 for fluid capacities. Test the radiator pressure cap to ensure it holds the rated pressure listed on page 177, and replace it if it fails to hold pressure.
Manual Section: Routine MaintenanceFrequently Asked Questions
How do I reset the JCB 457 service indicator?
The Operator Menu contains a "Reset" option that resets values like "Engine run time since the last reset" and "Total fuel used". To access this, stop the machine, engage the park brake, and push and hold the P1 button for three seconds to enter the Menu. Select "Reset" within the Operator Menu to clear these values. The "Hours remaining until service" is displayed in the Service Menu (page 77) and is not reset by this specific function.
What are the replacement specifications for air filter?
The manual indicates that air filter elements should be replaced when the air cleaner restriction device shows a red flag, or the secondary element should be changed every other time the primary element is replaced. The procedure involves removing the pre-cleaner and carefully extracting the primary and secondary filter elements, then installing new ones. The manual does not provide specific part numbers or detailed technical specifications for the replacement filters.
What are the replacement specifications for fuses?
When replacing fuses, always use ones of the correct ampere rating to prevent electrical system damage. The manual includes detailed fuse tables listing specific ampere ratings for each circuit — for example, 60A for heated mirrors and heated seat (PF1) and 30A for hazard-warning indicators (PF2), both shown on page 169. Refer to the Primary and Secondary Fuse tables in the Fuses and Relays section for the complete circuit ratings.
How do you fix JCB 457 wheel loader no start or hard start after preheat and ignition sequence?
Check the battery isolator and ensure the transmission is in neutral. Verify the engine oil and other fluid levels are within range per the specifications in the Routine Maintenance section. Inspect the fuses and clear any active warning lights before attempting another start.
