Part of the JCB Repair Manuals.
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.
