Description

Komatsu PC400-6 Hydraulic Excavator Parts Book PBCH400602 (PC400-32949 and Up) Chinese English

This listing is the Komatsu PC400-6 Hydraulic Excavator Parts Book PBCH400602 (PC400-32949 and Up) Chinese English issued by Komatsu (Changzhou) Construction Machinery Corp. under publication number PBCH400602. The cover identifies the machine as the Avance PC400-6 hydraulic excavator and limits applicability to serial numbers PC400-32949 and up. Every figure pairs an exploded illustration with a bilingual parts table so a parts clerk or technician can match index numbers to part numbers, quantities, and serial-break notes without guessing which variant belongs on the machine.

How the Catalog Is Organized

The opening pages explain how to read the list. Figure numbers are not continuous. A leading period marks an assembly; a double period marks a child of that assembly. Quantity is the piece count per machine or per assembly. The serial column records the engine or machine number range that uses the line. Codes printed between the part number and the name show supersession, interchange, kit-only supply, discontinued status, semi-finished parts that need machining, group parts that are not sold separately, paint notes, and cold-weather A (-30°C) or B (-50°C) items. When a part is ordered, the foreword requires the model, the engine serial number, and the service-meter reading.

Engine figures carry engine serial breaks such as #60721-67603 and #81057-. Chassis, hydraulic, cab, and undercarriage figures commonly use machine serial #32501- together with standard (-STD), long-carriage (-LC), loader, F.O.P.S., auto-greasing, and additional-piping options. That serial discipline is why the Komatsu PC400-6 Hydraulic Excavator Parts Book PBCH400602 (PC400-32949 and Up) Chinese English is useful for identifying the exact line rather than a look-alike part from a neighboring serial block.

IMAGES PREVIEW

Taken together, the book is a complete illustrated parts identity map for one serial family of the PC400-6. It does not teach teardown or torque procedures; it tells you which part number, gasket kit, hose, shoe, cylinder seal group, or service kit belongs on a given serial and option package, and which line superseded or interchanges with another.

Engine and Cooling Breakdowns

Section AA is the largest single engine block in the Komatsu PC400-6 Hydraulic Excavator Parts Book PBCH400602 (PC400-32949 and Up) Chinese English. Cylinder-head figures list valve-less head assemblies, intake and exhaust valves with oversize inserts (0.25 mm through 1.00 mm), valve guides sold as service parts, seats, springs, cotters, and crosshead assemblies. Separate plates cover the head cover, intake manifold and aftercooler for earlier and later engine serials, aftercooler water piping, air cleaner, exhaust manifold, turbocharger inner parts and oil piping, and two muffler serial groups. Bottom-end coverage includes the crankshaft, damper, piston, standard and hardening crank pulleys, oil pump, oil filters with and without bypass, oil cooler, and water drain valve. Fuel equipment is split across injection-pump mounting, pump body, governor, coupling, feed pump, piping, drive, filters, water separators, pre-filters, nozzles, and return lines. Cooling hardware distinguishes 198 mm and 212 mm fan pulleys, matching fan drives, 35 A and 50 A alternator mounts with hardening or non-hardening pulleys, and 7.5 kW / 11 kW starting motors with inner-part explosions. Gasket kits for the head, block, and water pump sit near the spare-parts and multilingual name-plate figures.

Hydraulics, Frame, and Controls

Hydraulic figures start at the tank and then walk the main valve connecting parts for base, 1-actuator, 2-actuator LC, attachment-line-less, loader, and kit layouts. Delivery lines are drawn both with and without in-line filters. Boom, arm, and bucket hose routes are separate from drift-preventive lock valves and their piping and clamps. Attachment circuits include 250 kg/cm² and 220 kg/cm² relief valves plus one- and two-actuator cross-valve brackets. Load-sensing lines, solenoid valves, the shuttle valve, and PPC work and travel lines close the hydraulic map. Revolving-frame plates add extra piping, auto greasing, F.O.P.S., and the deck strength kit. Cab coverage is option-dense: tilt and suspension seats, vandalism-protection doors and locks, air-conditioner versus heater harnesses, English monitor panel, floor-frame PPC plumbing for travel, work, and attachment pedals, and F.O.P.S. kits.

Undercarriage and Work Equipment

Undercarriage plates separate standard and LC track rollers, carrier rollers, the front idler and cushion, and several shoe styles including triple-grouser-with-hole, 300 mm wide, and 800 mm flat shoes. Track frames are catalogued by center guard, full roller guard, variable gauge, and under-cover combinations for both STD and LC machines. The swing circle, swing machinery, swing motor connections, and 3rd-speed swivel joint sit immediately ahead of the travel piping and final-drive explosions. Work-equipment coverage lists standard and heavy-duty booms, 4.0 m boom cylinders, arms in 2.4 m, 2.9 m, 3.4 m, 4.0 m and 4.8 m lengths, loader bottom-dump piping, and buckets from 1.2 m³ to 2.6 m³ in horizontal-pin and vertical-pin patterns, plus ripper and breaker-adapter figures. A 8890 kg counterweight and its mounting hardware appear in the guard section.

Service Kits and How to Order

The Y0 service section reprints major assemblies as supply parts: swing machinery, final drive, operator cab groups, shoe bolt-and-nut kits, track links, seat assemblies, the main pump in ten figures, cylinders, swivel joint, swing and travel motors, and the main valve families broken into many plates so internal sleeves, springs, O-rings, and holders can be ordered without buying a complete valve. Kit, group, and star symbols in the parts tables flag items sold only as assemblies or only through authorized distributors. That same symbol language appears throughout the Komatsu PC400-6 Hydraulic Excavator Parts Book PBCH400602 (PC400-32949 and Up) Chinese English, so a buyer can see at a glance whether a line is a single piece, a gasket kit, a discontinued supersession, or a cold-weather special.

Get the Parts Book and Identify the Correct Number

Use this catalog to identify cylinder-head hardware, injection-pump internals, radiator and fan-drive pieces, hydraulic tank and main-valve connecting parts, boom and arm lock-valve piping, track rollers and shoes for STD or LC frames, boom / arm / bucket assemblies, cab glass and harness options, and the service kits that rebuild pumps, motors, and cylinders. Correct part numbers and serial-break notes prevent ordering a hose, shoe, or valve group that belongs on a different PC400-6 option package. After payment the PDF is available immediately — no shipping wait — and can be opened on any device or printed at the bench for the figure you are working from.
