Component Documentation

Ordering incorrect hardware during a repair costs valuable shop time. This OEM catalog provides an exhaustive breakdown of the L170 skid steer loader, mapping every system from internal engine architecture to the final drive assembly. You can quickly navigate to fuel injection setups, water pump configurations, or alternator mounting structures using the hierarchical index. It also breaks down specialized factory add-ons like block heaters, demolition doors, and high-flow hydraulic kits. Every component section integrates hydraulic circuit schematics, electrical harness routing drawings, cab assembly views, and component cross-section views with precise reference numbers. These correlate directly to tables specifying exact part numbers and required quantities, ensuring you order the right hardware the first time.

System Technical Reference & Shop Utility

Beyond simple part identification, the manual includes mechanical metrics critical for component verification. You will find pressure relief settings for hydraulic check valves, such as the 65 PSI crack pressure, and thermal parameters noting the 71°C thermostat rating. Specific fastener sizing for engine blocks, manifolds, oil pans, and drainage plugs is explicitly listed. The engine data covers long-block variations and calls out serial-number-dependent parts like engine block bushings and oil pump seals. Always cross-reference machine serial numbers against these exact configurations before assembly to guarantee safe fitment and prevent severe system failures under load. Always securely block the loader lift arms with approved mechanical locks and relieve all system pressure before opening hydraulic lines to prevent severe crush hazards.

Although this publication is strictly an identification catalog and not a written step-by-step repair guide, the sequential exploded views act as a precise visual roadmap for dismantling and rebuilding assemblies that typically require expensive dealer service, such as the Rexroth AA20 hydrostatic pump or the Eaton/Vickers secondary control valves. Seeing the exact stacking order of internal shims, washers, and O-rings prevents costly rework. From a mechanical standpoint, when servicing these skid steers, technicians frequently encounter severe hydrostatic motor damage caused by failing to manually prime the case drain lines after a component swap. Additionally, phantom electrical problems are often traced back to the cab tilt pivot point, where the main wire harness connecting to the advanced instrument cluster is prone to chafing. Having the wiring diagrams and exact OEM harness layouts on hand makes tracing these electrical and hydraulic issues straightforward.
