Factory Service Repair Documentation with Wiring Diagrams

The New Holland LS180.B, LS185.B, LS190.B Skid Steer Loader and LT185.B, LT190.B Compact Track Loader PDF Service Repair Manual (P/N: 6-80050NA) is an OEM-level technical publication developed for professional technicians responsible for diagnosing faults, servicing core systems, and performing mechanical and hydraulic repairs on New Holland B-Series loaders. This factory documentation delivers approved workshop procedures covering engine systems, hydrostatic drive units, hydraulic circuits, electrical controls, and loader frame assemblies shared across wheeled and tracked configurations.

The New Holland LS and LT B-Series loaders are designed for demanding construction, site preparation, and material-handling applications where compact size, strong lift performance, and dependable traction are essential. While the LS models utilize a wheeled skid steer platform and the LT models operate on tracked undercarriages, both rely on similar powertrain, hydraulic, and control architectures. This manual serves as a primary reference for troubleshooting drive performance issues, restoring hydraulic output, servicing undercarriage or wheel drive components, and correcting electrical or control-related faults.

Powertrain & Drive System Technical Coverage

These loaders are powered by turbocharged diesel engines engineered for continuous operation under variable load conditions. This service repair manual includes detailed diagnostic and repair procedures covering fuel delivery systems, cooling assemblies, exhaust components, and engine-mounted accessories.

Machine movement is controlled through hydrostatic drive systems designed to deliver smooth, responsive control. The documentation provides technical guidance for servicing hydrostatic pumps and motors, drive chains or final drives, axle components (LS models), and track drive assemblies (LT models) to restore reliable propulsion and traction.
