2004 Kubota KX161-3 Excavator Illustrated Parts List (P/N RG918-8139-0)

This Kubota KX161-3 Illustrated Parts List, Code No. RG918-8139-0, identifies components for excavators from serial number 00001 onward. The 2004 publication combines exploded assembly views with part numbers, quantities, interchangeability symbols, and configuration-specific listings.

• Engine components: Exploded views cover the V2203-M-EBH-2 engine, including the oil pan, cylinder head, crankshaft, governor, injection pump, and nozzle holders.
• Hydraulic assemblies: Detailed parts breakdowns cover hydraulic pumps, control valves, rotary joints, swivel motors, drive motors, pilot valves, and hydraulic piping.
• Work equipment and undercarriage: Identify boom, arm, bucket, blade, and swing-bracket components, plus track rollers, idlers, and steel or rubber crawler parts.
• Electrical and cab equipment: Parts illustrations cover starters, alternators, wiring harnesses, switches, meters, cabin components, heating, and air-conditioning equipment.
• Parts matching: Serial-number notes and interchangeability markings distinguish component revisions, while a numerical parts index provides another route to the relevant assembly.

This catalog suits technicians, parts staff, and experienced owners who can use exploded views to identify components and match replacement parts to the machine’s configuration.

Component and Assembly Documentation

Figure groups S001–S135 organize the catalog, with additional pages for assembly variants. Numbered callouts connect each illustration to the corresponding part description, quantity, and part number.

Engine coverage extends into injection-pump components, starter and alternator internals, water-pump parts, and gasket kits. These breakdowns support parts identification; they do not provide step-by-step overhaul instructions, tightening procedures, or diagnostic tests.

The catalog’s assembly brackets and interchangeability symbols help distinguish complete assemblies from individual replacement items. The I.C. column also identifies noninterchangeable parts and substitutions that apply in only one direction.

Matching Hydraulic Parts to the Machine

Hydraulic listings separate the main control-valve assembly from its individual valve sections, including travel, swivel, boom, arm, bucket, blade, and service-port components. Pilot-control and oil-piping illustrations show the associated fittings and hoses.

Cylinder listings distinguish earlier and later boom, arm, bucket, and blade assemblies. Checking the relevant serial-number entry before selecting a cylinder component or seal kit helps avoid using a listing for the wrong production version.

Relieve hydraulic system pressure before loosening hydraulic lines or fittings.

Electrical, Track, and Cab Variants

Electrical coverage consists of component and harness placement illustrations with matching parts lists. Separate air-conditioning wiring pages support identification of that configuration, while serial-dependent listings distinguish changes to switches, meters, relays, and harnesses. These are parts illustrations, not electrical circuit diagrams for fault tracing.

Undercarriage pages distinguish steel and rubber crawler equipment, including standard and wide steel-track configurations. Cab and body sections extend to doors, glazing, covers, and seating; heater and air-conditioning breakdowns identify components such as the compressor, condenser, hoses, and unit wiring.

Selected Piston, Bearing, and Injection-Shim Sizes

The piston and crankshaft listing distinguishes standard pistons from +0.25 mm replacements. Crankpin bearing sets are listed in standard, −0.20 mm, and −0.40 mm versions, giving useful detail when identifying the replacement size associated with a part number.

Injection-pump shims are listed in 0.20, 0.25, and 0.30 mm thicknesses. These are cataloged component sizes, not instructions for setting injection timing or determining machining clearances.

PDF Navigation and Drawing Readability

Search, bookmarks, and fine detail: The scanned pages do not support usable text searches. Two bookmarks divide the file into broad sections; use the printed contents and numerical parts index for assembly lookup. Dense illustrations benefit from zooming, and some fine lines in the air-conditioning wiring layout are faint.

The download contains one printable PDF with 352 pages, including the front and rear covers and two blank pages. The catalog presents headings and parts descriptions in English, French, German, Italian, and Spanish.
