All 611 pages of this JCB 714 Service Manual PDF (OEM #9813/0550-3) focus on one goal: keeping your 714 and 718 Articulated Dump Trucks out of the shop and on the haul road. Inside, you get complete wiring diagrams for the transmission and instrumentation, hydraulic schematics covering both the primary and secondary pumps, and fault-finding procedures. Open to the suspension section for step-by-step rebuild instructions, or scan the torque tables to lock down every fastener. Torque your wheel nuts to 600 +/- 20 Nm and verify the new park brake pad material thickness measures exactly 15 mm before putting the machine back in gear. Every hour in the shop costs money. Grab this bookmarked download, pull it up on your tablet, and get the exact factory answer on the first try.

JCB JCB 714, 718 Articulated Dump Truck Common Problems This Manual Covers
JCB 714 articulated dump truck rear wheels difficult to rotate or brakes dragging after pad replacement p. 497
Inspect the brake caliper adjustment. Measure the service brake pad thickness and replace if below the minimum 2 mm (0.08 in.) allowed. Torque the park brake caliper bolts to 75-85 Nm (55.3-62.7 lbf ft) as shown on page 497. Verify the caliper backs off correctly to prevent drag.
Manual Section: BrakesHydraulic rams slow to operate or fluid appears cloudy indicating air or water contamination p. 262
Drain and flush the hydraulic system if the fluid is cloudy. Replace the return line filter with a genuine 10 Micron element as detailed on page 262. Refill the hydraulic reservoir to the level marked on the sight gauge. Test the main relief valve operating pressure.
Manual Section: Hydraulic System Fault FindingMachine steering feels heavy or unresponsive during operation at low engine RPM p. 525
Test the steering stand-by pressure at the test port and compare to the specification on page 525. Check for leaking lines or trapped hoses if pressure remains low. Adjust the compensator valve per the factory procedure if pressure is out of range.
Manual Section: Hydraulic SteeringWheel studs breaking or loose lug nuts discovered during daily walkaround inspections p. 137
Torque all wheel nuts to exactly 600+/-20 Nm (443+/-15 lbf ft) using a calibrated heavy-duty torque wrench. Follow the tightening sequence outlined on page 137. Inspect the hub and stud threads for stretching or physical damage before reinstalling the wheels.
Manual Section: General InformationEngine temperature gauge spikes into the red zone or coolant boils over during heavy hauling p. 85
Inspect the radiator fins for debris and clean with compressed air. Check the coolant level and top up to the specification on page 85. Mix the standard coolant to provide freezing protection down to -40 °C (-39 °F) as detailed on page 86.
Manual Section: EngineFrequently Asked Questions
How to reset JCB 718 service light?
The "Service Required" light is reset when data is downloaded by your JCB Dealer. If this light is illuminated, you should contact your JCB Dealer for assistance.
What are the replacement specifications for brake pads?
For new park brake pads, material thickness is approximately 15 mm (0.59 in.) for pad E and 20 mm (0.787 in.) for pad F. It is recommended to change park brake pads when only 4 mm (0.157 in.) of thickness remains. For service brake pads, the minimum allowed thickness is 2 mm (0.08 in.).
What are the replacement specifications for brake caliper components?
For the park brake, if any parts of the valve are damaged or excessively worn, the complete valve must be renewed. The seal kit for the park brake valve includes a Boot (1), 'O'Ring Seal (1), and Seal Polypak (1).
How do you fix JCB 714 articulated dump truck rear wheels difficult to rotate or brakes dragging after pad replacement?
Inspect the brake caliper adjustment. Measure the service brake pad thickness and replace if below the minimum 2 mm (0.08 in.) allowed. Torque the park brake caliper bolts to 75-85 Nm (55.3-62.7 lbf ft) as shown on page 497. Verify the caliper backs off correctly to prevent drag.
