New Holland C190 Compact Track Loader Parts Manual — 2006 and Newer

This New Holland C190 illustrated parts catalog covers the North American compact track loader configuration listed from January 2006 onward. It is built for parts identification and repair planning.

Parts Searches and Section Bookmarks

Finding an assembly: Headings and parts-table text are searchable, and the search guide explains figure-number searches. Embedded bookmarks open the figure index, main parts section, abbreviations, and hardware reference. Navigation is by broad section; illustration callouts are image-based.

The single printable English-language file is a 462-page PDF. It contains 438 illustrated catalog pages, five figure-index pages, one search-guide page, 14 abbreviation pages, two hardware-reference pages, one additional front page, and one blank page. All are included in the total.

Illustrated Drivetrain and Loader Assemblies

The following selected contents outline the catalog’s main groups. Additional illustrated equipment includes a cab jack kit and a foot-control shock-absorber kit.

• Engine internals: Exploded figures identify the cylinder block and head, valve mechanism, crankshaft, pistons, connecting rods, camshaft, and lubrication components.

• Cooling and fuel: Radiator, water pump, thermostat, fan drive, air cleaner, exhaust, fuel tank, injection pump, injectors, filters, lift pump, and injection lines.

• Drive and undercarriage: Tandem and gear pumps, drive motors, return manifold, hydraulic brakes, transmission centering, final-drive frames, rollers, idlers, sprockets, and rubber tracks.

• Loader hydraulics: Standard and high-flow boom and bucket layouts, control valves, cylinders, mounting-plate hydraulics, reservoir, filter, connect-under-pressure couplers, and front and rear secondary auxiliaries.

• Electrical equipment: Starter, alternator, battery cables, cab, engine, main, and chassis harnesses, optional advanced instrument cluster, diagnostic service plug, and two-speed and pilot-control harnesses.

• Chassis and attachments: Boom lock and float kit, hydraulic mounting plate, buckets, cutting edges, spill guard, pallet fork, cab doors and windows, seats, restraints, control handles, counterweight, and decals.

• Parts-ordering detail: Reference numbers, New Holland part numbers, quantities, descriptions, supersession notes, “if used” qualifiers, repair kits, service subassemblies, and components not serviced separately.

This catalog is suited to technicians and parts staff who can match exploded-view reference numbers to the machine’s installed configuration.

Parts Identification and Repair Planning

The alternating exploded-view and table format lets a technician follow an assembly from the machine-level layout down to individual brackets, hoses, fittings, seals, fasteners, and service kits.

The figures make it possible to confirm what is included with an assembly, what must be ordered separately, and which earlier part number has been replaced before a repair order is placed.

Scope: This is an illustrated parts catalog, not a workshop repair manual. It does not provide step-by-step removal and installation procedures, troubleshooting tests, torque sequences, hydraulic test methods, or electrical wiring schematics. Use the appropriate service manual for repair procedures and adjustment specifications.

Engine and Fuel Selection Notes

The engine section goes beyond external service items. It identifies the bedplate stiffener, crankshaft bearings and thrust washers, piston and ring kits, flywheel, camshaft gears, oil pump, and oil cooler. Fuel-system figures also distinguish rigid supply and return lines and the optional fuel shut-off kit.

Cylinder-head gasket selection is tied to measured piston protrusion, so the two listed gasket versions should not be treated as interchangeable.

The fuel shut-off kit calls for protective conduit where the line passes beneath the oil-fill tube, identifying a routing point where abrasion could damage the hose.

Pump, Valve, and Coupler Configurations

The catalog separates standard and high-flow hydraulics, conventional and pilot controls, and hand- and foot-control valves. These distinctions should be checked before selecting a pump, valve, hose, or control component.

Representative figures include the drive-motors-to-manifold layout, pilot-control-to-pump routing, and the Rexroth A22 pump sectional view. The pump breakdown distinguishes right- and left-rotation groups.

Control-valve seal-replacement figures identify service groups and kit contents. Some replacement valves are listed without a service breakdown available at the time of publication.

The coupler tables distinguish male and female breakaway couplers, matching halves, dust caps, adapters, repair kits, and components available only as complete assemblies. Special repair tool P/N 86539432 is listed for female flat-face coupler 393394A1.

Electrical and Cab Options

Main-harness selection depends on whether the cab has a service/run switch. The diagnostic-plug figure provides a connector view for the service plug used without the instrument cluster installed.

Other electrical groups identify backup alarms, horn and turn-signal equipment, remote jump-start components, and the warning beacon.

Cab figures separate heater-only and air-conditioned equipment and right-side throttle arrangements. These configuration differences also affect harnesses, controls, windows, and cab components.

Hardware References and Repair Preparation

Catalog abbreviations are defined in English, French, and Spanish. The hardware reference permits limited metric and inch substitution in some through-hole applications but warns against mixing metric and inch nuts, studs, bolts, or tapped threads.

Before servicing the boom, mounting plate, cylinders, or hydraulic lines, lower or mechanically support the lift arms, relieve stored hydraulic pressure, and isolate electrical power according to approved workshop procedures.

Selected Cylinder Dimensions for Parts Matching

The boom-cylinder list identifies piston rod 86536095 with a 1-3/4 in. diameter, alongside separate wiper, seal, and wear-ring entries.

For the bucket cylinder, three-piece seal 86563839 is specified for a 2-1/2 in. piston. These dimensions identify cataloged components; they are not wear limits or adjustment specifications.
