Komatsu PC220LC-6 Parts Catalog PDF — Serial 50001 and Up

Description

Komatsu PC220LC-6 Parts Catalog — Serial 50001 and Up

This is the complete Komatsu PC220LC-6 parts catalog covering main valve assemblies and the air conditioning system for machines from serial number 50001 onward, delivered as a single 630-page PDF. Every assembly is presented as an exploded illustration with itemized part numbers, quantities, and serial-number applicability, so you can trace a part from the diagram to the order table without guesswork. Whether you are rebuilding a main control valve, replacing a PPC lever, or sourcing an A/C condenser fan motor, the exact component is listed here.

Main Valve Assemblies

The main control valve section dominates this PC220LC-6 parts catalog, and for good reason — the valve design changed several times across the serial range, and each configuration has its own set of internal components. The catalog breaks the valve down across 11 standard sections plus separate 1-actuator, 2-actuator, and 3-actuator variants, each with its own serial-number breakpoints. You will find every spool, spring, sleeve, piston, poppet, ball, retainer, case, plug, O-ring, back-up ring, and mounting bolt itemized with its Komatsu part number. The exploded views show the exact order of assembly, which matters when you are rebuilding a valve body and need to know which seal goes where.

Service Valve and PPC Pilot Valves

The service valve and PPC valve sections cover the operator’s control input side of the hydraulic system. PPC valves for travel, work equipment, and attachment are each broken down into lever, shaft, spring, piston, seal, dust cover, bushing, collar, and damper components. Where the valve design changed between serial ranges, the catalog shows the specific parts for each range — for example, the travel PPC valve is documented across five distinct serial groups, each with its own body, lever, and damper part numbers. The service valve section includes the spool, plug, ball, retainer, case, and O-ring breakdown needed for a complete rebuild or partial replacement.

EPC, Suction, Timing, Shuttle, and Lock Valves

Beyond the main and pilot valves, this Komatsu PC220LC-6 parts catalog documents the supporting hydraulic components that are easy to overlook until they fail. The EPC valve assembly is listed as a complete unit. The suction and safety valve — used across multiple circuits and in several configurations — is broken down into sleeve, poppet, piston, plug, spring, seal, and O-ring components with serial applicability noted. The timing valve, shuttle valve, and lock valve each get their own exploded views and parts lists, covering internal balls, plugs, O-rings, springs, seats, and check valve elements.

Filters, Solenoid Valve, and Accumulator

Filtration and pressure control hardware is covered in detail. The attachment-line filter and main filter are shown with element, housing, cap, packing, seal, and O-ring part numbers. The five-solenoid valve block appears in three serial-specific versions, with each solenoid, tube, band, plunger, spring, spool, plug, and expander listed. The AL300-1 accumulator section includes the shell, bladder assembly, core, body assembly, seal kit, and every O-ring and back-up ring needed for a reseal.

Heater, Compressor, and Air Conditioning System

The air conditioning half of this PC220LC-6 parts catalog is just as thorough as the hydraulic side. Both the 2000 KCAL and 3300 KCAL heater assemblies are documented down to the case, radiator, fan, blower motor, resistor, and mounting hardware. The compressor assembly section covers the compressor, clutch, stator, rotor, hub, snap rings, and shims across two serial ranges. The cooling unit, core unit, blower assembly, filter box, condenser, and air damper case are each presented with their respective motors, relays, thermistors, servo motors, valves, hoses, clamps, and wiring harnesses — all with Komatsu part numbers and serial applicability.

Serial-Specific Coverage Is the Point

What sets a real Komatsu PC220LC-6 parts catalog apart from a generic parts list is serial-number accuracy. This PDF is built around serial breakpoints: the main valve changes at specific serial numbers, the PPC travel valve has five distinct configurations, the solenoid valve block exists in three versions, and the compressor changed at 52642. Each section states the serial range it applies to, so you are never guessing whether a part from an early machine will fit a later one. That level of specificity is what makes this catalog useful for a machine that has been in service for decades and may have had components swapped across the years.

Who This Parts Catalog Serves

This PC220LC-6 parts catalog is written for the people who keep these excavators running: independent hydraulic technicians rebuilding a main valve, fleet maintenance managers sourcing a replacement solenoid, parts counter staff who need to confirm a part number against a serial number, and owners who want to understand what is inside a valve before they pay someone else to open it. The exploded diagrams and itemized tables let you identify a component visually and confirm its part number, quantity, and serial applicability on the same page.

Order the Right Part the First Time

A wrong hydraulic valve spool or an incorrect seal kit is not just a return — it is downtime on a machine that may be on a deadline. This Komatsu PC220LC-6 parts catalog eliminates the guesswork by tying every internal component to an exploded illustration and a serial number. Whether you are ordering a single O-ring or a complete PPC valve assembly, you will have the part number and the fitment confirmation before you place the order.
