New Holland L160, L170 Common Problems This Manual Covers
New Holland L170 will not move under load, hydrostatic drive loses power on hills
Check the hydrostatic troubleshooting chart. Verify charge pressure first; a clogged charge filter is the usual culprit. Torque the pump relief valve caps to 135 N·m (100 ft. lbs.) after inspection, and confirm the relief setting holds at 238 bar (3500 PSI) before condemning the pump.
Manual Section: Hydrostatic Transmission Drive System IssuesHydraulic system runs hot with weak lift and slow bucket response
Work through the flow and overheat section. Drain a sample and check for foaming or milky oil, which points to a failing seal letting air or coolant into the circuit. Confirm system pressure against the main relief valve spec of 170-177 bar (2500-2600 PSI) on page 51, and torque relief valve hardware to 51 N·m (38 ft. lbs.) on reassembly.
Manual Section: Hydraulic System Flow, Pressure, and OverheatLift pump grinding or whining noise with reduced boom raise speed
Inspect the pump mounting hardware first; loosened bolts cause the whine before internal wear does. Torque pump mounting hardware to 39 N·m (29 ft. lbs.) per page 88 and pump body hardware to 35 N·m (26 ft. lbs.) per page 143. On the L170 confirm output matches 17.7 GPM (67.0 LPM) at 2900 RPM under 1000 PSI, listed on page 54; a low reading confirms internal pump slippage.
Manual Section: Hydraulic System Flow, Pressure, and OverheatEngine cuts out unexpectedly during heavy digging or loading
Run the engine no-start and stalling checks. Check fuel supply for restriction at the tank pickup and inline filter first since fuel starvation under load is the common trigger. Verify coolant level and check for overheat-related shutdown; cross-check cooling system capacity at 10.3 L (10.8 qt.) on page 50 if the system was recently serviced.
Manual Section: Engine No-Start and Running IssuesParking brake will not release or drags after release
Follow the parking brake testing procedures. Check the release cylinder and linkage for binding before assuming a hydraulic fault, and verify the actuating pressure reaches spec during the test sequence. A grinding noise during release usually means worn brake pucks needing replacement rather than an adjustment fix.
Manual Section: Parking Brake System TroubleshootingPilot control joystick loses signal or acts erratic in wet weather
Check the pilot control signal path referenced in the EIC troubleshooting, since a lost signal there disables boom and bucket spool unlocking. Inspect the joystick sensor connector for corrosion or moisture intrusion and clean contacts before replacing the sensor. Verify the instrument cluster reads the fault correctly rather than just going dark.
Manual Section: Electronic Instrument Cluster (EIC) TroubleshootingFrequently Asked Questions
How to reset the fuel filter on a New Holland L170 skid steer?
The manual describes draining the fuel filter water trap every 100 hours or sooner, and replacing the fuel filter every 500 hours. There is no mention of an electronic "reset" procedure for the fuel filter system. p. 152
What are the torque specifications for engine bolts on New Holland L160/L170 models?
The manual provides specific torque specifications for various engine components. For instance, cylinder head bolts should be tightened to 72-76 ft. lbs. (98-103 N·m) when oiled. p. 88
What are the error codes for the New Holland L170 skid steer?
The manual indicates that the Electronic Instrument Cluster (EIC) has a "FAULT" menu to view accumulated fault history. Fault items are displayed via backlighted symbols or bar graphs for parameters like Hydraulic Charge Pressure, Engine Oil Pressure, Hydraulic Oil Filter, Engine Air Filter, Hydraulic Oil Temperature, and Engine Coolant Temperature, rather than specific numerical error codes. p. 724
How can I reset the glow plug countdown on a New Holland L170?
To restart the glow plug preheat sequence on the New Holland L170, if the engine does not start within 30 seconds, turn the ignition key off and then on again. This will re-activate the automatic glow plug timer. p. 152
How will I receive this New Holland L160, L170 Workshop Manual?
This is a 904-page searchable PDF ready for immediate download. Works on any device, so pull it up on your phone while you're under the hood. No shipping, no waiting.
Are there any print restrictions on this New Holland L160, L170 manual?
