Engine and Engine Related Parts

The engine section covers the mounting brackets, stoppers, cushions, and hardware that secure the powerplant to the frame. Engine-related parts include the air cleaner mount (standard and quarry spec), the double-element air cleaner, and the auto-decel fuel control linkage. Every exploded view shows the assembly order and the exact fasteners required.

Cooling System

This section breaks down the radiator and oil cooler assembly, including the AL variants for LTK and KIPL use, the fan guard, radiator mounts, and the cover assemblies that direct airflow. Individual cores, seals, and mounting hardware are listed with part numbers for each serial range.

Fuel Tank and Related Parts

The fuel tank chapter details the tank itself, the fuel line routing with water separator and additional fuel filter, and the associated fittings, clamps, and brackets. The exploded views show the complete line path from tank to engine so you can trace and replace any section without dismantling the entire circuit.

Electrical System

Covers the battery (including the large-capacity option), battery box, wiring harnesses for the engine, horn, relay, auto-decel system, and the main machine harness. The harness diagrams and connector callouts help you identify the correct plug-and-play replacement for your serial number.

Hydraulic System

The hydraulic section is the largest in the catalog and spans the tank with protector, main valve (with plugs and mount bracket), suction line, delivery line, oil cooler lines, return line, drain line, and the attachment circuits for boom drift, arm and bucket, supplementary filter piping, pilot line routing, accumulator mounting, and the one-attachment configuration. It also covers the blade line, travel line, swing line, solenoid valve and its line, pressure switch block, and the PPC main line.

Each circuit is presented as an exploded illustration with every hose, tube, flange, O-ring, and clamp called out and listed in the adjacent parts table. Serial-number breakpoints are flagged, so you can confirm whether your machine uses the early or late configuration before ordering.

Main Revolving Frame and Operator’s Compartment

The frame chapter covers the revolving frame (blade spec) and boom foot pin. The operator’s compartment section is extensive: seat with belt, seat inner parts, the cab with FOPS, front window, door, electrical components, inside covers, installation parts, additional lamps, top guard, and the tunnel-spec cab. Floor frame sections break out the base, safety lock lever, travel lever, fuel control, PPC work and travel lines, blade control, foot pedal mounting, and the harness routing for the hour meter.

Guards and Covers

This section lists the hood, hood mounting parts, hood for tunnel spec, left and right side covers, partition with water separator and additional fuel filter, lamp cases (standard and quarry spec), hand rail, rear-view mirror, counterweight and counterweight hook, counterweight mounting, and the strength-type under cover. Each panel and its fasteners are shown in exploded view.

Swing Circle, Travel, and Lower Piping

Swing components include the swing circle, swing machinery, related parts, and the swivel joint mounting for blade spec. Travel and lower piping covers the travel piping, final drive, blade line, and blade blind line. The exploded views make it straightforward to identify a specific bearing, seal, or hose without removing the entire assembly.

Undercarriage

The undercarriage chapter covers the front idler, idler cushion, track roller, carrier roller, track shoe (triple grouser with hole, 450 mm wide), track frame (blade spec and quarry spec), and track roller guard. Each roller and idler is broken down to individual components—shaft, bushing, collar, seal group, and O-ring—so you can order just what you need for a rebuild.

Work Equipment

Boom, arm, and bucket sections cover standard, one-attachment, and tunneling configurations. Cylinder listings include the boom, arm, bucket, and blade cylinders. Bucket options include the 0.09 m³ width 450 mm vertical-pin type, reinforced 0.3 m³ width 750 mm horizontal-pin type, shallow 0.3 and 0.35 m³ buckets, and the 0.3 m³ quarry-spec bucket. Teeth, side cutters, pins, spacers, and wear plates are all listed with the correct fasteners.

Marks, Accessories, and Service Kits

Decal and plate listings cover machine identification, safety, and branding marks. The tool kit section lists the standard hand tools supplied with the machine. Service kits round out the catalog with breakdowns for the main pump (six parts), boom/arm/bucket/blade cylinders, swing motor, travel motor, main valve (seven-valve and one-attachment), PPC valve for travel and work equipment, and pilot valve.

Why This Parts Catalog Belongs in Your Workshop

Ordering the wrong part costs more than the part itself. It costs the return shipping, the restocking fee, the re-order, and the downtime while your excavator sits idle. The Komatsu PC71-7 spare parts catalog eliminates that cycle by giving you the correct part number, the correct quantity, and the correct serial-number applicability before you pick up the phone or open the parts portal. The exploded views are not generic line drawings—they show the actual assembly as it appears on the machine, with every fastener, seal, and bracket indexed to the parts list.

This is the same catalog the parts desk uses to look up components, and having it in your own workshop means you can verify a number independently, check whether an interchangeable part (marked C1 in the listings) will work in place of the original, or confirm that a discontinued item has been superseded by a current part number. The manual also flags assembly-only parts (marked #) so you know when a component must be ordered as a complete unit rather than as an individual piece.

Whether you maintain a single machine or a fleet, this catalog pays for itself the first time it saves you from a wrong-part order.
