New Holland LS160 & LS170 Skid Steer Loader Parts Catalog 2005 (P/N 604.04.321.00)

New Holland parts catalog P/N 604.04.321.00, 1st Edition 05–2005, for 2005 LS160 and LS170 skid steer loaders. It provides component identification, part numbers and assembly references for replacement-parts ordering.

Searchable Parts Lists and PDF Limitations

Text search and drawing detail: PDF text search is available; there are no embedded PDF bookmarks. Small callouts in the checked, densely labeled parts drawings are easier to read when enlarged. Some illustration plates are blank, including the LS160 engine installation and Engine Electric plates, although their corresponding parts lists remain.

Missing introductory pages: The introductory contents list references identification/version and maintenance-parts sections on printed pages 25–32. Those pages are absent from this PDF.

One printable PDF contains 689 pages, including the original cover and 16 blank separator/end pages. English parts descriptions appear alongside multilingual equivalents.

Engine, Hydrostatic Drive and Loader Parts

The following selected catalog sections show the main coverage. Other entries include paint references and threaded-insert installation tools.

• Engine components: Cylinder blocks, cylinder heads, valve gear, fuel-injection equipment, lubrication and cooling parts, plus LS170 turbocharger entries.

• Hydrostatic drive: Front and rear piston pumps, the center manifold block, hydraulic motors, final-drive gearboxes and brake components.

• Loader hydraulics: Standard and High Flow arrangements, boom and bucket cylinders, tandem-circuit control valves, auxiliary hydraulics and seal-kit contents.

• Electrical components: Main and cab electrical layouts, harness identification, starter and alternator parts, and regional lighting equipment.

• Cab and controls: Cab enclosure and heater kits, hand- and foot-control components, seats and multifunction handles.

• Chassis and attachments: Boom locks, wheels and tires, counterweights, bucket cutting edges, tooth bars, utility forks and pallet-fork mounting assemblies.

This catalog is suited to mechanics, parts staff and experienced owners who can match assembly callouts and applicability notes to their loader’s configuration.

Part Numbers, Assembly Views and Ordering

The alphanumeric index links part numbers to figures, sequences and reference positions. This supports parts sourcing for routine maintenance and repair planning, whether you start with a known number or identify a component in an available illustration.

Examples of included exploded views are the LS160 Tier 2 cylinder head, Final Drive, Piston Pump—Front, Bucket Cylinder and Control Valve. Their callouts connect individual components with parts-list entries and repair-kit contents.

Applicability matters: Engine serial breaks apply to engine parts. Hydraulic hoses, couplers, final-drive components and horn/turn-signal equipment have their own figure-specific machine serial notes. These distinctions help prevent ordering a part from the wrong assembly revision.

The ordering instructions also explain that illustrations and part numbers can change after publication and direct buyers to confirm current replacement-part requirements with a dealer.

Pump, Valve and Cylinder Variants

Eaton gear-pump listings distinguish single pumps from double-pump High Flow equipment for each loader model. Auxiliary-control sections separately identify Eaton and Eaton/Vickers valve assemblies.

Hand versus foot control: The tandem-circuit valve lists distinguish yellow foot-control valves from blue hand-control valves, with different spool-centering kits. High Flow electrical arrangements also distinguish a toggle switch behind the left hydrostatic handle from a rocker switch on the ignition panel.

Cylinder breakdowns identify rods, pistons, wear rings, seals and kit contents. Components marked as not serviced separately must be distinguished from individually listed replacements.

Electrical Coverage and Repair Scope

Electrical documentation provides component layouts and harness identification, rather than circuit-level wiring schematics or diagnostic test procedures. Regional cab and lighting entries distinguish North American and European equipment; some on-road kit entries also identify Italian loose parts.

This is a parts catalog, not a step-by-step repair manual. Use the applicable service instructions for disassembly, adjustment, lifting-arm support and hydraulic-pressure safety.

Selected Cylinder Wear-Ring Dimensions

For the bucket cylinder, wear ring 80771701 is listed as 2.002 in. ID × .375 in. thick. The boom-cylinder list identifies wear ring 80783874 as 2.252 in. ID × .375 in. thick.

These are component dimensions for parts identification, not cylinder-bore wear limits or repair adjustment specifications.
