Part of the New Holland Repair Manuals.
Wrenching on a New Holland EC160 crawler excavator? This 712-page New Holland EC160 service manual PDF (OEM #73179382) is the factory workshop book for the whole machine, undercarriage to superstructure. You get full wiring diagrams for the electrical system, hydraulic schematics for the twin variable displacement pump and 6-way control block, plus step-by-step teardown procedures for travel and swing gearboxes, multi-disk brakes, and hydraulic cylinders. Wear limit tables tell you exactly when parts are done: measure chain stretch across 4 links, and if the 685.8 mm new spec has stretched to 697.5 mm, that track is finished. The hydraulic reservoir holds 250 liters; fill it right the first time. Guessing at wear limits kills undercarriages. Bookmarked by section, this PDF opens on any device, so bring your tablet straight to the machine and start wrenching.

New Holland EC160 Common Problems This Manual Covers
New Holland EC160 hydraulic functions weak and slow after filter service, boom won't lift a full bucket
Check the hydraulic oil level before tearing anything apart; the reservoir holds 250 L (66.1 gal). Air trapped after service mimics pump wear, so bleed the circuits: cycle each function fully in both directions for about 1 minute per the procedure on page 270, switching briefly back to neutral, until each consumer has run at least 5 minutes total.
Manual Section: Hydraulic System Troubleshooting p. 270Hydraulic oil temperature climbs into the red after an hour of digging, fan running constantly
Shut down and blow out the radiator and oil cooler fins with compressed air from the fan side, then check for mud packed between the cooler cores. Drain and replace contaminated oil; the hydraulic system takes 250 L (66.1 gal), spec on page 69. Verify fan belt tension and confirm the oil level after refill.
Manual Section: General TroubleshootingTrack chain slapping the frame, machine wanders during straight travel, sprocket teeth look hooked
Measure chain stretch across 4 links: new spec is 685.8 mm (27 in), replace at 697.5 mm (27.468 in), wear limits on page 71. Check bottom roller diameter too; 155 mm new, 142 mm fully worn. Adjust track tension per the undercarriage service procedure on page 94 and clean packed mud from rollers and idlers daily.
Manual Section: Undercarriage p. 94Boom drifts down with joystick in neutral, controls feel spongy and inconsistent
Test pilot pressure at each joystick output first; erratic readings mean air in the pilot circuit, so bleed each function roughly 1 minute in each direction before condemning parts. Inspect the primary valve for contamination and torque it to 20 Nm on reassembly, spec on page 291. Check cylinder rod seals for internal leak-down under load.
Manual Section: Hydraulic System p. 291Hydraulic hoses weeping at the crimped fittings, wet oil film along the boom lines
Replace any hose weeping at the crimp; never attempt a repair. Install the new hose with slack, since hoses change length between -4 and +2 percent under pressure, tolerance on page 550. Torque flange connections evenly and check alignment; maximum permissible deviation from parallel is 0.3 mm per page 573. Route lines clear of sharp edges.
Manual Section: Fittings, Pipes and Hoses/ Welding for Maintenance and Repair/ Sealing, Protecti p. 550Frequently Asked Questions
How do I reset the error code on a New Holland EC160?
The failure memory can be displayed, printed, and stored by the EDS-diagnostic tester. If the failure memory is not reset and 40 faults have been reported, the faults are automatically overwritten and renumbered. p. 480
What are the replacement specifications for the hydraulic filter?
The return flow filter element (10 m absolute) for the hydraulic oil reservoir should be replaced every 500 operating hours. The filter element for the filling pump swing circuit should be replaced every 3000 operating hours. p. 70
What are the replacement specifications for the fuel filter?
The fuel filter is part of the engine maintenance. The engine oil and filter should be changed every 250 operating hours. p. 69
What is the tightening torque for the M16 bolts on the swing bearing?
The M16 x 90 bolts (grade 10.9) used for the swing bearing must be tightened to 250 Nm (185 lbft). p. 121
What is the valve clearance for the engine?
The valve clearance for both the inlet and exhaust valves on the engine is 0.25 mm / 0.01 inch when the engine is cold. p. 61
