Part of the New Holland Repair Manuals.
This 928-page New Holland E80 Shop Manual (OEM #87360644) breaks down the complete Hydraulic Excavator down to the Mechatro Control System, hydraulic circuits, and travel components. Inside, you get full wiring diagrams for the electrical system, hydraulic schematics covering every circuit on the machine, and a troubleshooting section built around real fault codes, like E01 EEPROM data faulty, walking you through diagnosis instead of leaving you guessing at the panel. You also get torque specs, standard maintenance intervals, and complete engine teardown procedures from disassembly through reassembly, plus lubricating and fuel system coverage. Confirm your E80 tips the scale at 8,230 kg complete weight, and check the overload alarm threshold before you chase a phantom hydraulic fault. No motions operating on your machine? This manual walks the exact diagnostic path New Holland techs use. Bookmarked by system, so you jump straight to hydraulic, electrical, or engine sections without scrolling through 900 pages.

New Holland E80 Common Problems This Manual Covers
New Holland E80 excavator loss of pilot pressure and hand controls completely fail to operate.
Check the pilot pump output and hydraulic oil level, ensuring the 102 L capacity is met as detailed on page 27. Inspect the hand control levers for leaks. If replacing pilot lines, torque the PF 3/8 joints to 74 ± 5 Nm as specified on page 64.
Manual Section: System Troubleshooting p. 27Main hydraulic system pressure drops and boom or arm becomes totally unresponsive.
Verify main relief valve pressure reaches 29.4 MPa using a gauge. Check the hydraulic schematic for pressure test points. If the relief valve is faulty, replace it and torque the M12 mounting bolts to 36.3 ± 3.9 Nm as shown on page 61.
Manual Section: System Troubleshooting p. 100Engine stalls under load or completely fails to start after a hydraulic lock event.
Drain hydraulic pressure from the system before attempting to restart. Inspect the controller for an E01 EEPROM data faulty code on page 663. If the main relief valve is stuck closed, remove it and verify it opens at exactly 29.4 MPa as specified on page 100.
Manual Section: System Troubleshooting p. 663Frequently Asked Questions
What are the replacement specifications for hydraulic seals (system-wide)?
For the travel motor, all hydraulic seals (O-ring, oil seal, floating seal) should be replaced once used, even if they show no visible damage. This is a general rule to ensure proper function and prevent oil leakage. p. 615
What is the tightening torque for M16 x 50 socket bolts on the slewing unit?
The tightening torque for the eight M16 x 50 socket bolts used for mounting the slewing unit is 279 Nm (210 lb ft). Loctite #262 (Three Bond #1350) should also be applied to the bolts. p. 519
What is the standard valve clearance for the intake and exhaust valves on the E80 engine?
The standard valve clearance for both intake and exhaust valves on the E80 engine is 0.40 mm (0.016 in). This measurement is critical for proper engine operation. p. 731
What is the maximum allowable grinding allowance for the cylinder head lower face warpage?
The maximum grinding allowance for the cylinder head lower face warpage is 0.3 mm (0.012 in). If the measured value exceeds this limit, the cylinder head must be replaced. p. 756
