Part of the New Holland Repair Manuals.
This 656-page New Holland E15 Shop Manual (OEM #87360157 NA) puts the complete factory teardown for your Hydraulic Excavator in one PDF. Open it up and you get wiring diagrams for the electrical system, full hydraulic schematics covering the pump, control valve, pilot valve, and slewing motor unit, plus dedicated troubleshooting sections for overheating under load and jerky, sluggish hydraulic response. You also get the engine section: disassembly, inspection, reassembly, lubrication, and fuel injection pump/governor work, all laid out the way New Holland techs actually work. Torque that 3/4-inch O-ring fitting to 12±0.5 kgf·m (87±4 ft-lbs), and heed the pinhole-leak warning on page 15 before you go hunting hydraulic leaks with your bare hand. No more flying blind on a machine that's bleeding oil somewhere you can't see. Bookmarked for fast jumps between sections; pull it up on your phone and get back under the machine.
