2006- New Holland L170 Skid Steer Loader Parts Catalog

This illustrated parts catalog covers the 2006–Present New Holland L170 skid steer loader, with North American catalog headings. It supports component identification and parts selection; it does not contain written step-by-step repair or diagnostic procedures.

Searchable Parts Tables and Figure Navigation

Text search and drawing detail: Search the figure index and parts tables by text or figure number. Six section-level PDF bookmarks provide access to the introductory material, index, parts catalog, abbreviations, and conversions. Individual figures are not bookmarked. Drawing callouts are image-based, and small reference numbers in dense layouts require zooming.

Supplied as one printable PDF with 436 pages total: 412 pages of parts drawings and tables, a five-page figure index, 14 abbreviation pages, and two hardware-conversion pages. One figure-search instruction page, one additional introductory page, and one blank page are already included in that total.

Engine, Hydrostatic Drive, and Loader Component Breakdowns

These selected catalog sections outline the main coverage. Other entries include acoustical equipment and counterweight kits.

• Engine components: Cylinder block, cylinder head, crankshaft, pistons, timing gear case, oil pump, fuel injection, and turbocharger parts drawings and tables.

• Cooling and intake: Water pump and thermostat components, radiator and oil-cooler assemblies, Donaldson air cleaners, and standard, aspirated, or catalytic mufflers.

• Ground drive and brakes: Final-drive chains, axle assemblies, RH/LH gearboxes, hydrostatic motors, piston pumps, and separate brake layouts for pilot-control machines.

• Loader hydraulics: Standard and high-flow boom, bucket, and auxiliary plumbing; cylinder seal kits; selector valves; Eaton and Eaton/Vickers secondary control valves.

• Electrical and controls: Main, cab, chassis, engine, and pilot-control harness drawings, instrument clusters, diagnostic-plug identification, and hand- or foot-control components.

• Cab and attachments: Cab enclosure and demolition-door kits, seating, mounting plates, wheels, buckets, tooth bars, and pallet-fork assemblies.

Suited to parts staff, mechanics, and owners who can match reference-numbered drawings to the assemblies and control configuration fitted to their machine.

Engine Assemblies and Parts Selection

Reference numbers connect the illustrations to OEM part numbers, quantities, and application notes, helping you compare the installed assembly before ordering repair parts. The figure index locates fuel-injection, water-pump, and alternator-mounting sections by figure number.

Long-block contents: The L170 service-engine entry specifies excluded accessories, including the starter, flywheel housing, cooling fan, alternator, and exhaust manifold. This distinction helps establish which existing components must be accounted for when comparing a replacement long block.

Serial-dependent components: The Cylinder Block list distinguishes applications for the block, bushing, and draincock. L160 references appear in shared component lists and selected kit sections; these references do not make this a complete L160 parts catalog.

Hydrostatic Pumps and Hydraulic Configurations

The Rexroth AA20 pump section separates right- and left-hand rotary groups, hydraulic controls, pressure-relief valves, and the internal gear pump. Exploded views identify the component relationships and corresponding service assemblies.

Hand-control and foot-control valve listings distinguish their spring and spool-centering kits. Separate standard, high-flow, and pilot-control layouts identify the applicable hoses, tubes, couplers, and cylinder seal kits.

The catalog also marks components that are not serviced separately. These entries help distinguish individually listed replacement parts from components supplied within a larger assembly.

Electrical Fitment and Loader Hardware

Harness applications: Main-harness listings distinguish machines with and without a service/run switch. The optional advanced instrument cluster and diagnostic service plug have separate entries. Electrical illustrations show component locations and harness routing, rather than circuit schematics or fault-isolation charts.

Cab and attachment equipment: Parts breakdowns cover block-heater kits, demolition doors, the boom lock, and hydraulic mounting-plate components. Accessory listings also identify the cab jack kit and threaded-insert installation tools by part number.

Raised lift arms require approved mechanical supports, and hydraulic work requires appropriate pressure-isolation precautions.

Hardware Compatibility Notes

The hardware-conversion notes distinguish mounting-hole clearance from thread compatibility. Mixing metric and inch threads can damage the fastener or tapped hole; the substitution table does not authorize that interchange.

Selected Gasket and Oil-Seal Dimensions

The Cylinder Head parts list identifies gasket SBA111147510 as 1.2 mm thick.

For the timing gear case, oil seal SBA198636160 is listed with a 55.0 mm outside diameter and 33.8 mm inside diameter. These are catalog dimensions for identifying the listed replacement parts, not engine inspection limits or adjustment specifications.
