Part of the New Holland Repair Manuals.
Wheel end off the axle housing, planetary carrier on the bench: the 825-page New Holland LW 170.B service manual pdf, OEM 6-49712, is written for the wheel loader job you are starting this hour. Schematic foldouts close out the book, mapping power control and distribution, lighting circuits, transmission controls and the full hydraulic circuit. Troubleshooting with pressure checks repeats through steering, power train, brakes and hydraulics, so a soft lift or a lazy loader control valve gets traced to a reading instead of a hunch. Removal and installation procedures reach the bucket cylinders, coupler solenoid locking valve and ride control accumulator. Set the main relief valve at 248 to 252 bar (3596 to 3654 psi); pull the planetary carrier locknut to between 700 and 1000 Nm (516 to 737 lb-ft). Every hour that loader sits in the yard, nobody is billing. Bookmarked and searchable, bought once and yours for as long as you own the machine.

New Holland LW 170.B Common Problems This Manual Covers
New Holland LW 170.B hydraulics lock up mid cycle and the seat belt light comes on
Check the seat and seat belt interlock circuit in the electrical troubleshooting procedures that start on page 209 before condemning the loader valve. Wiggle test the seat switch harness under the cushion with the key on. Confirm pilot supply reaches the hydraulic controller, then verify main relief settings hold 248 to 252 bar (3596 to 3654 psi).
Manual Section: Electrical Specifications and Troubleshooting p. 209Engine bogs down and stalls when pushing a full bucket into the pile
Run the stall test procedure in the engine section before touching fuel components. Compare converter stall speed against drivetrain drag. Drain and refill the cooling system to its 25.5 liter capacity if you find overheating, and inspect the fuel supply from the 246 liter tank for a restricted filter or sucking air at the pickup.
Manual Section: Stall Tests p. 15Lift arms slow or bucket curl drops off completely as oil warms up
Test loader pump differential pressure and cutoff pressure at the test ports before pulling the distributor. Verify circuit relief valves on the bucket A and B ports hold 290 bar (4206 psi). Torque the combination anticavitation and circuit relief cartridges to 200 Nm (147.5 lb-ft) per page 683 when you reinstall.
Manual Section: Hydraulic Specifications, Troubleshooting, And Pressure Checks p. 683Growling or whine from the wheel end under load, metal flake in the axle oil
Drain the wheel end and cut the magnetic plug open before ordering parts. Inspect the planetary carrier and sun gear teeth for spalling. On reassembly, torque the locknut securing the planetary carrier to 700 to 1000 Nm (516 to 737 lb-ft) as listed on page 519, and torque the bolts securing the wheel end to the axle housing to 390 Nm (288 lb-ft) per page 521.
Manual Section: Front Axle p. 519Hydraulic oil running hot and thin after a few hours of heavy loading
Clean the oil cooler core and radiator fins with air blown from the fan side first. Verify the 193 liter hydraulic system is filled to the sight glass with the arms down. Replace the hydraulic filter, then check the fan reversing switch operation in the electrical section before blaming the pump.
Manual Section: Cleaning the Hydraulic System p. 15Cab A/C blows warm air or cools erratically on hot days
Recover and weigh the refrigerant charge before adding anything. The system takes 1.6 kg of HFC-134a per page 763. Inspect the compressor clutch gap and check the A/C pressure switch circuit. Torque steel 3/8 inch tubing fittings to 31 to 36 Nm when you reseal a leaking joint.
Manual Section: Air Conditioning Troubleshooting and System Checks for Systems with HFC-134a Refrigerant p. 763Frequently Asked Questions
What are the torque specifications for steel hydraulic fittings on the New Holland LW 170.B?
The torque specifications for steel hydraulic fittings vary by size and type. For example, a 1/4 inch 37-degree flare fitting requires 72 to 144 pound-inches (8 to 16 Newton-metres), while a 1/2 inch straight thread with O-ring requires 540 to 804 pound-inches (57 to 91 Newton-metres). p. 11
How do I clear error codes on the New Holland LW 170.B?
To erase engine fault codes, press and hold the fault code diagnostic switch while turning the ignition switch to the run position. Continue holding the switch for five seconds after the diagnostic lamp turns off, then turn the ignition switch off, wait 5 seconds, and turn it back on without starting the engine. p. 331
How do I calibrate the transmission clutch packs on the New Holland LW 170.B?
Transmission clutch calibration is performed using the digital display. Navigate to the service page, select 'CLUTCH CALIBRATION', and press 'TEST'. The system will automatically calibrate clutches K1 through K4, KV, and KR when the transmission oil is at an operating temperature of 80° C (176° F). p. 322
What is the engine oil capacity for the New Holland LW 170.B?
The engine oil capacity for the New Holland LW 170.B is 14.2 liters (15 U.S. quarts) when performing an oil change with a filter replacement. p. 15
What is the cylinder head bolt tightening torque for the F4GE0684F engine in the New Holland LW 170.B?
The cylinder head fastening screws are tightened in three phases. The first phase is 50 ± 5 Nm (5 ± 0.5 kgm), the second phase is 90 degrees, and the third phase is an additional 90 degrees. p. 75
