Part of the New Holland Repair Manuals.
New Holland service manual 48005365, English, April 2016. It covers both wheeled excavators in monoboom and triple articulation form, and the WE190B on standard and wide axles.
Where the two models differ, the book prints both figures. The swing bearing to undercarriage screws take 250 - 310 N·m (184 - 229 lb ft) on the WE170B and 540 - 600 N·m (398 - 443 lb ft) on the WE190B.
It has 33 electrical schematic sheets, hydraulic schematic frames 01 to 03 and diagnostic code troubleshooting with a cause and a remedy for each code.

New Holland WE170B, WE190B Common Problems This Manual Covers
Code 7001: low pressure on power steering
The troubleshooting tables blame a damaged gear pump. With the engine on, check the pressure at port P of the priority valve. Replace the gear pump only if it reads below 2 bar. The gear pump section covers removal and installation.
Manual Section: Electrical systems - Troubleshooting related to diagnostic code 7001 p. 882Code 7002: low pressure on the brake valve
The listed cause is an unsatisfactory accumulator charge. The remedy is to check the accumulator charge. The Brakes and Controls section covers the accumulators, the brake valve and the 75 bar (1088 psi) service brake setting.
Manual Section: Electrical systems - Troubleshooting related to diagnostic code 7002 p. 883Code 9612: short to ground on electrovalve Y241, pump P1 regulator control
The code table calls for replacing electrovalve Y241. The listed cause is a short circuit on electrovalve Y241 itself. The electrical schematic sheets cover the UCM proportional electrovalves of the main valve, and the harness localization pages show where the connectors sit on the machine.
Manual Section: Electrical systems - Troubleshooting related to diagnostic code 9612 p. 890Code 7021: battery charge control of alternator G1 damaged with engine On
The diagnostic code table for 7021 lists a mechanical cause, alternator damaged, and the remedy is to replace the alternator. The same table also has an electrical branch with its own wiring check, and the electrical schematic sheets start with the power supply circuit.
Manual Section: Electrical systems - Troubleshooting related to diagnostic code 7021 p. 886Frequently Asked Questions
Which machines and versions does the New Holland WE170B / WE190B service manual cover?
It covers the WE170B and WE190B wheeled excavators, both in monoboom and triple articulation versions. The WE190B is also covered with standard and wide axles. Both models appear on every subsection title. The book prints no serial ranges, so match it by model and engine type. The WE150B is not in this book. Part number 48005365, English, April 2016. p. 1
What engines and power ratings do the New Holland WE170B and WE190B use?
The WE170B uses engine type F4GE9684F*J602, rated 105 kW (142.76 Hp) at 2000 RPM. The WE190B uses F4GE9684E*J607, rated 118 kW (160.44 Hp) at 2000 RPM. Both displace 6.7 l (1.8 US gal). This book covers the systems around the engine: air cleaners, fuel filters, injection, intake and exhaust, aftercooler and cooling. A full engine overhaul is in a separate Engine Service Manual. p. 41
What are the fuel, hydraulic and engine oil capacities of the New Holland WE170B and WE190B?
Both models take 274 L (60.3 UK gal) of fuel and 16 L (3.5 UK gal) of engine oil. The cooling system holds 22 L (4.8 UK gal), and the hydraulic oil tank holds 87 L (19.1 UK gal). Total hydraulic oil differs: 230 L (50.6 UK gal) on the WE170B and 235 L (51.7 UK gal) on the WE190B. p. 46
What travel and swing pressures does the New Holland WE170B / WE190B manual give?
Travel is 370 bar (5365 psi) on both models. Swing is where they differ: 390 bar (5655 psi) on the WE170B and 360 bar (5220 psi) on the WE190B. The attachment circuit on triple articulation machines is 340 bar (4930 psi). Pilot pressure is 45 bar (653 psi), and the service brake is set at 75 bar (1088 psi). p. 37
Does the New Holland WE170B / WE190B manual include wiring diagrams, hydraulic schematics and diagnostic codes?
Yes. It has electrical schematic sheets 01 to 33, running from power supply through to the CAN bus, and hydraulic schematic frames 01 to 03. The 7000, 8000 and 9000 series codes each list activation conditions, mechanical and electrical causes, and a remedy. For example, code 9612 is a short to ground on electrovalve Y241, the pump P1 regulator control. p. 977
