Part of the JCB Repair Manuals.
All 438 pages of this JCB 8014 Service Manual PDF (OEM #9803/9350-6) focus on one thing: getting your 8014, 8016, 8018, or 8020 mini excavator back in the dirt. Open to the hydraulic section for complete schematics detailing the 'O' ring face seal systems and 'Torque Stop' hose routing. You also get clear wiring diagrams, a dedicated troubleshooting guide, and extensive standard torque settings for zinc-plated fasteners. Verify your starter motor nominal output is hitting 1.1 kW, or tighten the crankshaft carrier to the block at exactly 27 Nm. Guessing at electrical faults costs money and patience. Grab this bookmarked file, pull it up on your shop tablet, and trace the issue right at the machine.
