New Holland LS190.B (NA Series) 2006–2011 Skid Steer Loader Full Parts Catalog (P/N 87043497)

This 481-page PDF covers the New Holland LS190.B Skid Steer Loader - NA in illustrated parts catalog format. It combines 224 numbered parts figures with corresponding reference tables for part number, quantity, description, supersession, kit contents, and application notes. The catalog is suited to parts-counter staff, shop mechanics, and experienced owners who can match an installed configuration to an exploded view; it is not written as a step-by-step repair guide.

• Engine and fuel systems: Maps the four-cylinder engine from mounting and cooling components through the cylinder block, cylinder head and valve mechanism, crankshaft, pistons and connecting rods, camshaft, lubrication system, water pump, intake and exhaust manifolds, fuel-injection pump, filters, and related lines.
• Hydrostatic drive: Breaks down the tandem-pump mounting, pump-to-manifold plumbing, single- and two-speed drive motors, two-speed valve assembly, final drive, transmission centering, gear pumps, and the Rexroth AA22 pump with its internal gear pump, rotary groups, hydraulic control, relief valves, and locking elements.
• Standard, high-flow, and pilot hydraulics: Separates boom and bucket plumbing by configuration and covers the main control valve, hand- and foot-control valve assemblies, pilot-control routing, seal kits, mounting-plate hydraulics, boom and bucket cylinders, reservoir and filtration, connect-under-pressure couplers, and secondary front and rear auxiliaries.
• Electrical and control equipment: Identifies cab, engine, main, chassis, two-speed, and pilot-control harness assemblies, plus the optional advanced instrument cluster, diagnostic plug, backup alarm, remote jump-start hardware, horn and turn signal, electric power kit, and warning beacon.
• Chassis, cab, and attachments: Includes the chassis, floor plates, mounting plate, boom and boom lock, boom-float kit, cab and door assemblies, windows and wiper, heater and air-conditioning hardware, hand/foot/pilot control linkages, seats and belts, counterweight, buckets, and pallet fork.
• Figure-based lookup: The opening index is keyed to the figure numbers used throughout the PDF. Parts tables identify “If Used” items, replacements and supersessions, kit contents, components not serviced separately, and hardware quantities; an English/French/Spanish abbreviation guide and metric-inch hardware conversion reference are included at the end.

Configuration-Specific Coverage

The catalog separates standard and high-flow plumbing, single- and two-speed drive motors, hand, foot, and pilot controls, alternative high-flow valve assemblies and their matching harnesses, and cab heat or air-conditioning equipment. Optional-equipment figures cover the advanced instrument cluster, front and rear secondary hydraulics, remote jump start, rear fenders, boom float, cab jack, and multiple bucket styles.

Some control-valve tables include LS190 or LT190 components alongside LS190.B entries. Those shared breakdowns do not broaden the catalog’s stated LS190.B - NA coverage; follow the model qualifier and installed component details before selecting a part. The tables also flag assemblies whose internal components are not serviced separately or were unavailable individually at the time of printing.

Examples of the Included Parts Figures

Named figures include Rexroth Pump AA22, Rotary Group, Right Hand Rotation, Hydraulics - High Flow, Pilot Controls, Connect Under Pressure Couplers, Optional Advanced Instrument Cluster, and Heater and Air Conditioning. These are exploded or component-layout views rather than hydraulic or electrical schematics. Numbered callouts connect each illustrated item to its ordering information, including replacement numbers, included seals or hardware, and cross-references to related figures.

Scope Before You Buy

This is an illustrated parts catalog, not a service or repair manual. It does not provide removal and installation sequences, disassembly and reassembly instructions, hydraulic circuit schematics, electrical wiring diagrams or pinouts, diagnostic charts, pressure-testing procedures, torque tables, calibration data, or repair adjustments.

Coverage is identified only as New Holland LS190.B Skid Steer Loader - NA; no model-year or serial-number range is supplied. Confirm the machine identity and installed configuration before ordering parts.

For repair work involving a raised boom, stored hydraulic pressure, heavy components, or electrical isolation, use the appropriate service manual and machine safety procedures. This PDF supports parts identification and repair planning but does not replace workshop repair literature.
