Description

Komatsu PC80MR-3 Parts Catalog – Serial F00003 and Up

This is the full parts catalog for the Komatsu PC80MR-3 excavator, covering machines from serial number F00003 onward. It is the document a parts counter, workshop, or owner uses to identify exactly which component, fastener, seal, hose, or assembly belongs on a specific machine. Every figure is exploded and every callout is tied to a Komatsu part number with the quantity required.

With 882 pages of illustrated parts breakdowns, the Komatsu PC80MR-3 parts catalog covers the complete machine from the cylinder head to the bucket teeth, with the swing machinery, undercarriage, control valve, hydraulic piping, operator’s cab, and mark plates all broken out into individual serviceable items.

What makes this catalog useful is the level of disassembly it goes to. Each major assembly is shown exploded on its own figure with numbered callouts, and every callout maps to a part number, description, and quantity. That means the fuel injection pump is broken down into individual springs, o-rings, plugs, and solenoids; the swing motor into pistons, swash plates, brake discs, and shafts; the travel motor into final drive gears, floating seals, and relief valve cartridges. Where a component changes at a specific serial number, the catalog lists the break and gives you the correct part for your machine’s range.

What This Parts Catalog Covers

The Komatsu PC80MR-3 is a compact excavator with an offset boom, and the parts catalog reflects that with detailed coverage of the boom swing cylinder, the swing bracket, and the 2-piece boom option. The engine section supports the full top-end and bottom-end teardown, including the valve train, camshaft, crankshaft, pistons, and the gear housing that drives the fuel injection pump. The cooling and lubrication sections cover the water pump, thermostat, oil cooler, and the oil filter assembly, while the fuel section goes from the tank and water separator through the feed pump, fuel filter, and injection pump to the injector nozzles.

On the hydraulic side, the catalog includes the main hydraulic pump sub-assemblies, the 9-spool and 10-spool control valve blocks with their individual spools, springs, retainers, and o-rings, and the full range of pilot piping for the PPC valves. The travel motor coverage spans both early and late serial ranges with the appropriate final drive part numbers. The swing machinery section covers the motor, reduction gear, and brake components.

For the undercarriage, you get the track frame, idler, recoil spring, track rollers, carrier rollers, sprocket, and the different track shoe options including steel, rubber, and road circulation versions. The cab section covers the full operator station, including the seat, wiper system, heater, air conditioning, and the cab mounting hardware.

The work equipment section is where the attachment coverage lives: standard and long arms, standard and 2-piece booms, bucket cylinders, bucket links, and a wide range of bucket sizes from 400 mm ditch cleaning buckets up to 800 mm general-purpose buckets, plus the blade and blade cylinder.

Who This Komatsu PC80MR-3 Parts Catalog Is For

This is the reference used when you need to order the right part the first time. Whether you are rebuilding a swing motor, replacing a hydraulic hose, chasing a leak in the pilot circuit, sourcing a replacement bucket tooth, or just identifying a fastener from a figure, the catalog gives you the part number and quantity to order. It is equally useful for workshops maintaining a fleet, for parts departments quoting jobs, and for owners who want to understand what is inside their machine before it comes apart.

Because the catalog covers serial number F00003 and up, it also documents the running changes Komatsu made to the PC80MR-3 over its production life. That is important when a machine has been rebuilt or updated and you need to confirm whether a specific component matches your serial range.
