New Holland LS140 & LS150 Skid Steer Loader Parts Catalog 2005 (P/N 604.04.320.00)

• Covers New Holland LS140 and LS150 skid steer loaders across earlier and later engine builds as well as the separate Tier 2 engine assemblies, with parts plates for the cylinder block and head, valve train, timing gear and governor, lubrication, fuel injection, and cooling systems.
• Breaks down the hydrostatic drive through the final drive, transmission-centering linkage, hydrostatic pump and motor, front and rear piston pumps, case drain, and standard or European on-road brake configurations.
• Maps the working hydraulics from the bucket and boom circuits to the model-specific lift cylinders, gear pump, hand- and foot-control valves, connect-under-pressure couplers, check valve, reservoir, filter, and oil cooler.
• Separates North American, European, and Fiat-Hitachi configurations, with Fiat Kobelco applicability noted where specified; coverage includes cab electrical equipment, road and work lighting, horn and turn-signal changes, decals, on-road equipment, and regional attachments.
• Identifies cab and operator-control options such as early and late headliners, heater and enclosure kits, standard and suspension seats, foot or hand controls, boom lock, mounting plate, wheels, chassis, counterweight, and cab-jack components.
• Supplied as a 559-page PDF of New Holland Catalog No. 604.04.320.00, First Edition, May 2005, with exploded parts illustrations, callout-based lists, a recommended stock list for five machines, and a numerical part-number index.

This parts catalog identifies the correct service part for an LS140 or LS150 configuration. It is suited to technicians, parts-counter staff, and experienced owners who can match figure notes and machine identifiers before ordering; it is not written as a step-by-step repair manual.

How the Callouts and Parts Breaks Work

Each illustrated plate is paired with a list showing the callout number, New Holland part number, quantity, description, modification code, and applicable model. The C, D, and F change markers identify parts used up to a change, from a change, or within a stated serial range. Cross-references point to assemblies broken down elsewhere, while the symbols identify repair-kit contents, parts not serviced separately, and items no longer available as individual service parts. Page headers carry the assembly code, sequence, and page update date. Parts descriptions appear in English, Italian, French, German, Spanish, Portuguese, Dutch, and Danish.

New Holland notes that the listed part numbers were current at publication and may change, so confirm supersessions against a current dealer catalog before ordering.

Representative exploded views include Cylinder Head, LS140/LS150, Tier 2, Hydrostatic Pump & Motor, and separate Piston Pump, Front and Piston Pump, Rear plates. Other drawings cover Control Valve, Hand & Foot Controls and Cab Enclosure Kit, Door Attaching & Wiring. They show component relationships and callout positions for repair planning and parts ordering, but should not be treated as an assembly sequence.

Engine, ECN, and Market Breakpoints

The engine pages use paired early/late notes: before LS140 engine S/N 76992 and LS150 S/N 74975, then after LS140 S/N 76993 and LS150 S/N 74976. Separate Tier 2 cylinder-head, valve-cover, and rocker-arm plates follow. Those distinctions continue through internal engine and fuel-system listings, so model designation alone is not enough to select every engine repair part.

Other changes are handled by date, Engineering Change Notice, market, and machine serial number. Cab electrical listings split at ECN 116959 (06/02), and the hydraulic control-valve material separates configurations before and after ECN 118426. Horn and turn-signal sections provide before/after machine serial breaks for North America, Europe, and Fiat-Hitachi machines. Headliners and heater headliners are divided into old-style and new-style versions at 06/02, while the control sections distinguish hand controls from foot controls and standard from deluxe valve equipment.

Treat these breaks as parts-selection boundaries. Mixing earlier and later cylinder-head, piston, timing, or fuel-system components can create an incompatible repair and risk internal engine damage; cab harness and hydraulic-valve choices also need to match the listed region, ECN, and control layout.

Attachments, Tools, and Service-Manual Limits

The catalog includes breakdowns for buckets, tooth bars, utility and pallet forks, universal mounting plates, European attachments, and factory paint listings. A dedicated tools plate identifies threaded-insert installation tools 86600665, 86600666, 86600667, and 86600668, and the recommended initial stock section lists filters, seals, relays, switches, bearings, hydraulic repair kits, and service items for a five-machine fleet.

This publication does not contain removal and installation procedures, disassembly instructions, torque tables, hydraulic test pressures, wear limits, electrical troubleshooting charts, or wiring schematics. Use the matching service documentation for those tasks. Parts identification also does not replace safe repair practice around a raised boom, stored hydraulic pressure, or electrical power; follow the machine-specific safety and service procedures before beginning work.
