Identify Every Illustrated Part on the WA470-6

The Komatsu WA470-6 Wheel Loader Parts Book PBCW470600 Serial AD0001 and Up is the bilingual parts catalog used to match a physical component to its printed part number before you order. Cover and title pages name the machine as the WA470-6 wheel loader and limit applicability to serial numbers WA470-AD0001 and up. Each illustrated group sits on a left-hand figure page with index callouts; the facing list gives PART NO., DESCRIPTION (English with Chinese), Q’TY, and SERIAL No. so you can see whether a line applies to the whole AD0001-and-up range or only from a stated engine serial such as 560001-, 560347-, 560016-, 562775-, or 565940-.

This is not a shop repair narrative. It does not walk through disassembly steps or publish torque charts as a service manual would. What it does provide, at catalog depth, is the breakdown of assemblies, sub-assemblies, and service-only cartridges so a parts person or technician can order the correct gasket, injector line, clutch pack hardware, bucket edge, or cab glass without guessing from a worn stamping.

How Figures, Indexes, and Ordering Notes Work

The foreword explains the layout used throughout the Komatsu WA470-6 parts book. FIG. No. identifies the illustration, not the spare part. INDEX numbers on the drawing match the list. DESCRIPTION uses a leading “.” for an assembly and “..” for pieces inside a sub-assembly. Quantity is per machine unless the line is a constituent of an assembly, in which case quantity is per that assembly. Engine-volume SERIAL No. columns track engine serials; chassis-volume columns track the machine serial.

Symbol codes printed in the PART NO. and DESCRIPTION columns tell you when a later part supersedes an earlier one, when two lines are interchangeable, when a discontinued item is replaced by the line above or by a set listed in the description, when a piece is sold only as an assembly or only through authorized distributors, when a group is not a supply item, when a KIT refers to service-kit tables, when a part ships semi-finished, and when paint or cold-weather notes apply. Cold-terrain codes in the book are (A) for -30°C specification and (B) for -50°C specification. PAINT(1) means undercoat only at shipment; PAINT(2) means a color different from the machine body color.

When you place an order the foreword asks you to state part number, name, quantity, machine model code, machine serial number, engine serial number, and service meter reading. Optional equipment and attachments are listed alongside standard items, so the same catalog covers ECSS, 3-spool valves, load-meter harnesses, emergency steering, auto grease, lock-up torque converter, climbing-speed-up engine pieces, and EU noise-reduction frame covers where those figures exist.

Taken together, those groups let a technician explode the SAA6D125E-5 engine shown in the cylinder-head footer, the KTR90-232E turbocharger, common-rail fuel hardware, cooling pack, full powershift transmission and axles, implement and steering hydraulics, monocoque ROPS cab, and the bucket or grapple actually bolted to the lift arm. Option rows sit next to base rows, so a machine with lock-up, ECSS, emergency steering, load meter, auto grease, or a climbing-speed-up pulley set still maps to a figure number instead of a generic “see dealer” note.

Engine, Fuel, and Aftertreatment Breakdowns

Engine figures in the Komatsu WA470-6 Wheel Loader Parts Book PBCW470600 Serial AD0001 and Up start at the cylinder head assembly 6251-11-1100 and run through intake and exhaust valve inserts in several oversize steps (0.25 mm through 1.00 mm), valve guides, springs, crosshead assemblies, and the multi-piece cylinder-head gasket set with oil and water grommets. Rocker housing covers, breathers, and the intake manifold group add the boost-pressure and intake-air-temperature sensors listed on the manifold figure.

Turbocharger figure A1530-A3K9 mounts assembly 6506-21-5010 and points inward to the KTR90-232E core: turbine rotor, blower impeller, journal and thrust bearings, seal rings, turbine and blower housings, and the V-band. Separate EGR figure families exist for base machines and for EPA 3rd / EU 3rd regulation machines, covering valve and cooler mounting, cooler piping and air vents, valve lubricating-oil piping, and the EGR oil pump inner parts. Heat shields and mufflers have climbing-speed-up counterparts. Cold terrain A specification appears on the oil-pressure switch / coolant heater accessory and on the oil pan and suction tube figure.

Fuel hardware is common-rail: supply pump and rail, supply and return piping, rail inner parts, supply-pump inner parts including the feed pump, 1-5/8 fuel filter and service-only cartridge, 1-1/4 pre-filter with priming pump, injectors and spill tube, return line, and fuel controller. Charging and starting lists both 50 A and 75 A alternators (hardening-pulley and standard mount) and both 7.5 kW and 11 kW starting motors, each with an inner-parts figure for brushes, housings, and related pieces.

Driveline, Hydraulics, Structure, and Attachments

Power-train figures separate the front and rear drive shafts from the torque-converter and transmission package. Converter coverage includes a lock-up variant. Transmission lists split the forward/reverse clutch, reverse and 2nd clutch, 3rd and 4th clutch, case, main relief valve, and the left- and right-hand main valves across multiple sheets, then input shaft, output shaft, and coupling. Front and rear axles each receive final-drive (left and right), three differential sheets, a brake group, and housing mounting parts.

Hydraulic figures begin at the tank—standard and emergency-steering—and move through main valves for ECSS, two-spool, and three-spool machines, the steering demand / orbitrol valve, and the pump with dedicated suction, steering, implement, transmission, emergency-steering, LS, drain, and fan circuits. Cylinder and PPC lines for dump, lift, ECSS, and attachments are drawn as separate hose and tube groups so a leak can be traced to one indexed hose rather than a whole circuit description.

Frame and cab coverage includes the front frame (3-spool and auto-grease versions), rear frame (including EU noise reduction arrangement 2), hinge pin, steering cylinders, under covers, tool box, and the remote-grease / auto-grease feeder layouts. The operator section is the monocoque ROPS cab: doors, glass, wiper, interior trim, air-conditioner inner parts and ducting, column and orbitrol, floor harnesses, loader levers and PPC hoses, brake accumulators, and the bucket positioner, including the log-lumber grapple positioner variant.

Work-equipment sheets name bucket families by struck capacity and 3170 mm width, plus rock bucket, log grapple, fork tube, both-side dump bucket, bolt-on edges, side guard, and tooth options. Wheel sheets call out 26.5-25 tubeless rims and L-3 / L-4 tire constructions. Closing volumes list bilingual marks and plates, tool kits, the China fire extinguisher, and YO service kits that reopen hydraulic pumps, cylinders, fan motors, and main valves as inner-part explosions.

Who Uses This Catalog Day to Day

A workshop running mixed WA470-6 serials uses the Komatsu WA470-6 parts catalog to settle supersession questions: a square, diamond, or star next to a line tells you whether to order the number printed, the number above it, or a kit instead of a loose piece. A machine owner replacing a leaking EGR cooler can stay on the EPA/EU 3rd figure family instead of the non-regulation cooler piping. A parts counter building a clutch or injector order can read quantity per assembly rather than inventing a bill of materials from memory. Because Chinese and English share every description column, the same PDF works for a Changzhou-built machine operated by an English-speaking shop or a bilingual parts desk.

Get the Correct Part Number Before You Order

The Komatsu WA470-6 Wheel Loader Parts Book PBCW470600 Serial AD0001 and Up supports parts identification and ordering across the engine, cooling pack, fuel system, electrical harnesses, torque converter and transmission, axles and brakes, hydraulic pumps and valves, frames, ROPS cab, guards, tires, and work equipment for WA470-6 machines from serial WA470-AD0001 onward. Using the printed part number, index, quantity, and serial column prevents mixing a climbing-speed-up pulley with a hardening pulley, a 50 A alternator inner kit with a 75 A kit, or a 3-spool PPC hose set with a two-spool set. Instant PDF delivery after payment means you can open the figure on a phone, tablet, or shop PC, print the exploded view you need, and send the PART NO. to your supplier the same day—no printed-book wait and no shipping delay.
