Part of the New Holland Repair Manuals.
This is the full factory repair manual for the New Holland L180, L185 and L190 skid steer loaders and the C185 and C190 compact track loaders, the same service information a dealer technician works from. It covers the whole machine: the diesel engine, fuel, air intake, cooling and lubrication, the starting and electrical systems with the wiring diagrams, the primary, secondary and high-flow hydraulic power systems, the hydrostatic drive and power coupling, the axles and final drives, the wheels and rubber tracks, the differential steering and parking brake, the single loader arm and attachment coupler, and the cab, controls and environment control. Every section carries the specifications, pressures, fault finding and step-by-step overhaul procedures, so whether yours is wheeled or tracked, you can put a fault right instead of guessing.

New Holland L180, L185, L190, C185, C190 Common Problems This Manual Covers
Machine drive is weak, slow or tracks to one side.
Usually low charge pressure or a worn drive pump or motor. The Hydrostatic Drive section covers the charge pressure test (minimum 360 psi), the tracking adjustment and the drive pump and motor overhaul to restore even, full-power drive.
Manual Section: Hydrostatic Drive and Power CouplingLoader arm is slow, drifts down or auxiliary hydraulics are weak.
A worn main or high-flow pump, a stuck valve or leaking cylinder seals are the usual causes. The Hydraulic Power Systems and Loader Arm sections cover the pressure tests and the pump, valve and cylinder overhaul to restore lift and auxiliary flow.
Manual Section: Hydraulic Power SystemsCompact track loader tracks are loose, worn or coming off.
The Wheels and Tracks section covers the rubber track tension adjustment, the rollers, idlers and drive sprockets and the undercarriage inspection and service to keep the tracks tensioned and running true.
Manual Section: Wheels and TracksMachine will not start or a control or sensor fault appears.
The Starting and Electrical System section carries the wiring diagrams, the starting and charging system checks and the control and sensor diagnostics so you can trace a no-start or an electrical control fault to its source.
Manual Section: Starting and Electrical SystemFrequently Asked Questions
The drive is weak, tracking to one side or the machine creeps - where do I start?
The Hydrostatic Drive section covers the drive motors and pumps, the charge pressure test (minimum 360 psi) and the tracking and neutral adjustment, so you can find a worn pump or a charge pressure problem behind weak or crabbing drive.
The loader arm is slow, drifts down or the auxiliary hydraulics are weak - what does the manual cover?
The Hydraulic Power Systems and Loader Arm sections cover the primary, secondary and high-flow circuits, the lift cylinders and the attachment coupler with the pressure tests and the seal and valve overhaul to restore lift and auxiliary flow.
Does the manual cover both the wheeled skid steers and the tracked compact track loaders?
Yes. It covers the L180, L185 and L190 wheeled skid steer loaders and the C185 and C190 compact track loaders, including the Wheels and Tracks section with the tire fitment and the rubber track undercarriage service.
Does this manual include the wiring diagrams and control diagnostics?
Yes. The Starting and Electrical System section carries the wiring diagrams, the starting and charging systems, the lighting and the controls with the sensors and diagnostics, so you can trace an electrical or control fault properly.
Which hydraulic oil and charge pressure should these machines use?
They use New Holland Ambra Auto Supreme hydraulic oil, and the hydrostatic charge pump should hold a minimum of 2482 kPa (360 psi), or 362 psi on machines with pilot controls. The full specs are in the General and Hydraulic sections.
