New Holland L185 Skid Steer Parts Catalog

• Engine, cooling, and fuel systems: Maps the radiator and coolant-recovery group and the complete three-cylinder engine, with separate figures for the valvetrain, rotating assembly, timing control, turbocharger, lubrication, cooling, injection pump, injectors, and fuel lines.
• Hydrostatic drive: Separates standard and pilot-control tandem-pump layouts, European pump plumbing, single- and two-speed drive motors, final drive, transmission centering, the Rexroth AA22 pump, internal gear pump, rotary groups, and relief valves.
• Loader hydraulics: Breaks down hand-, foot-, and pilot-control valves; standard and high-flow boom and bucket plumbing; mounting-plate hydraulics; cylinders; filters and reservoir; connect-under-pressure couplers; and secondary front and rear auxiliary assemblies.
• Electrical equipment: Identifies starter and alternator assemblies, battery cables, cab/engine/main/chassis harnesses, instrument-cluster options, the 26-pin diagnostic service plug, alarms, road lighting, and two-speed and pilot-control harnesses.
• Chassis and operator station: Covers the chassis, boom and boom lock, float kit, mounting plate, bucket families, pallet fork, cab and doors, heater and air conditioning, controls, seats, belts, counterweight, and on-road equipment.
• Illustrated parts data: Pairs 231 numbered figure groups with Ref / Part Number / Qty / Description tables, including replacement notes, kits, "if used" qualifiers, and components that are not serviced separately.

This 492-page PDF is an illustrated parts catalog for the New Holland L185 skid steer. Every machine page carries the coverage line L185 SKID STEER - NA (1/06-), identifying North American L185 coverage beginning January 2006. The catalog does not assign a blanket machine serial/PIN range, so option and build configuration remain the decisive fitment checks. It is best suited to technicians, parts personnel, and experienced owners who already understand the repair at hand and need exact component identification rather than a beginner-level service guide.

Configuration-Specific Coverage

Important splits are called out at both figure and line-item level: standard versus high-flow hydraulics, single- versus two-speed hydrostatics, hand versus foot control, pilot-control machines, right-hand throttle, optional advanced instrument cluster, heater or air conditioning, and on-road equipment. Despite the NA heading, dedicated Europe figures cover the tandem-pump arrangement and on-road hydraulic brake. The main electrical harness is also separated between machines with and without the cab service/run switch, while high-flow listings tie particular valves to the matching wire harness. These distinctions help prevent a repair from being planned around the wrong valve, hose, pump, or harness.

Component and Part-Number Detail

The engine listing identifies assembly 87039745 as a three-cylinder engine supplied without the alternator, with its internal engine and fuel equipment distributed across linked figure groups. Each illustration is followed by the corresponding part table. Notes identify superseded numbers, replacement relationships, included subcomponents, service kits, "not illustrated" items, and parts marked NSS - Not Serviced Separately.

Representative plates include Cylinder Head - Valve Mechanism, Fuel Injection Pump, the Diagnostic Plug, Rexroth Pump AA22, Control Valve - Models with Pilot Control, and Boom (L185). The diagnostic-plug figure shows connector pin positions, and the Rexroth pump plate provides exterior and sectional views. These are parts-location and assembly-reference drawings, not repair sequences.

What This Catalog Does Not Include

This is not a workshop repair manual. It does not provide removal and installation sequences, disassembly and reassembly procedures, overhaul instructions, torque specifications, fluid capacities, pressure-test methods, wear limits, calibration data, troubleshooting flowcharts, wiring diagrams, or hydraulic schematics. Some tables contain "INSTRUCTION" cross-references to related figures, and a small number of kits list an instruction sheet as a supplied item; neither is a substitute for an executable service procedure. Use this catalog to establish the correct part group, number, and replacement trail, then use the applicable service and operator documentation for repair steps, testing, adjustments, and safety requirements.

Before disconnecting hydraulic lines or working around the boom, lower and mechanically secure the boom, isolate the machine, and release stored hydraulic pressure in accordance with the applicable service instructions. The hardware appendix permits certain inch/metric substitutions only in punched or drilled mounting holes. It excludes tapped holes and cross-standard nuts; forcing a near-size fastener can strip threads or damage a housing. Shared control-valve tables also place L185 entries alongside C185, LS185.B/LT185, and LT190 references, so match the model line and control type before selecting a repair part.
