JCB 8056 Common Problems This Manual Covers
JCB engine turns over normally after a fuel filter change but will not start p. 170
Bleed the air from the lines using the procedures found in the fuel system section on page 170. Verify the tank holds adequate diesel, noting the maximum capacity is 70 Litres (15.4 UK Gal). Prime the hand pump until resistance is felt before attempting another start.
Manual Section: Fuel SystemTemperature gauge spikes into the red zone during heavy operation or reduced cooling system performance p. 142
Inspect the radiator matrix for debris and clean the fins with compressed air. Check the expansion tank level and top up the system with JCB High Performance Antifreeze to the 13.5 Litres (3.0 UK Gal) capacity. Ensure proper winter protection down to -40 °C (-39 °F) as detailed on page 142.
Manual Section: Fluids, Lubricants and CapacitiesBoom and stick cylinders move sluggishly under load or exhibit low overall hydraulic response p. 131
Check the hydraulic tank sight glass with the machine parked on level ground. Fill the reservoir with JCB Special Hydraulic Fluid 46 if the level falls below the minimum mark. Note that the full system holds exactly 106 Litres (23.32 UK Gal) as documented on page 141.
Manual Section: Fluids, Lubricants and CapacitiesHigh pitched squealing noise from the engine compartment during startup or heavy electrical loads p. 159
Inspect the fan belt for wear, cracking, or glazing on the friction surfaces. Adjust the alternator bracket until you achieve a deflection of exactly 10 mm (0.4 in) as specified on page 140.
Manual Section: EngineFrequently Asked Questions
What are the replacement specifications for Fuel filter?
The manual specifies two fuel filter elements for replacement: a 5 Micron Primary Fuel Filter/Sedimenter Element and a 30 Micron Secondary Fuel Filter/Sedimenter Element. The procedure for replacing these elements is outlined in the 'Replacing the Fuel Filter Elements' section on page 184.
How do you fix JCB engine turns over normally after a fuel filter change but will not start?
