Howo WD615 Parts Catalog – 354 Pages of OEM Part Data

Howo WD615 Parts Catalog isn’t something you pick up for light reading. It’s a 354-page parts breakdown for the WD615 engine family used in Howo dump trucks (6×4 and 8×4), concrete mixers, and tractor units. If you’ve ever tried to order a replacement piston ring or a water pump gasket without a factory part number, you know the fun of getting the wrong box and losing a day. This catalog stops that nonsense.

I’ve torqued enough head bolts to know that cross-referencing parts from a generic interchange list gets you a pile of metal that doesn’t fit. The WD615 is a Chinese-built inline six that shares some architecture with the Steyr WD615 but has its own casting revisions. Without the OEM parts breakdown, you’re guessing on bearing shells, injector nozzles, and timing gear sets. That guess costs time and money. This catalog gives you the exploded view, the part number, and the supersession history for every fastener, seal, and casting listed in the Howo factory system.

What This Parts Catalog Covers: Dump Trucks, Mixers, Tractors

From the OCR run on this document, the first five pages break down the exact vehicle configurations: 8×4 dump truck, 6×4 concrete mixer, 8×4 concrete mixer, and 6×4 tractor. Each section in the catalog corresponds to those chassis layouts, so you don’t get water pump part numbers meant for a 4×2 chassis when you’re working on a 6×4. The catalog organizes parts by vehicle application and then by system—engine, cooling, fuel injection, driveline, brakes. No mixing of platforms.

For a job like swapping the injection pump on a WD615 in a concrete mixer, you need the correct pump housing and governor parts. The catalog lists them with the Howo factory number, not a cross-reference that may or may not match. Pages 122 through 148 cover the fuel system alone, including the inline injection pump housing, delivery valves, and plunger assemblies.

Why Factory Part Numbers Beats Aftermarket Guessing

Third-party parts catalogs (the ones from parts stores that aren’t automakers) love to group several part numbers under one “fits” entry. That works fine for light bulbs but not for engine bearings. The WD615 has main bearing cap bolts that stretch to a specific length. If you get a bolt from a generic kit that’s 2mm longer, you risk bottoming out in the block. The OEM catalog lists the exact bolt length, thread pitch, and torque specification for the block—page 67 for the cylinder head bolt set, page 89 for the main bearing cap bolts. Those numbers come from Howo’s own engineering, not a warehouse clerk’s guess.

A word on the Automotive Industry Overview that some parts catalogs reference: they’ll claim “OEM spec” but skip the revision letter. The Howo WD615 went through at least three piston ring pack changes between 2005 and 2010. This catalog accounts for those revisions. If you’re pulling a head off a 2008 6×4 dump truck, you want the ring set with the correct second-ring taper. The catalog shows it.

Real-World Use: Rebuilding a WD615 in a 8×4 Dump Truck

You’re in the shop with a customer’s 8×4 dump truck that lost oil pressure. You pull the pan and find a spun rod bearing. The crank needs grinding, and you need a set of bearing shells for the .25mm undersize. Without the catalog, you call the dealer, give them the VIN, wait forty minutes for a part number. With the catalog, you flip to the engine section, find the connecting rod assembly, note the factory part number for the .25mm undersize shells, and order them directly. The exploded view on that page shows the thrust washer orientation and the side clearance spec. One phone call, done.

For the Internal Combustion Engine internals, the WD615 uses a wet-liner design. The catalog lists the liner part numbers by height code, the O-ring sets, and the shim thicknesses for liner protrusion. You can rebuild the bottom end without pulling the block if you have the correct liner shim chart—and it’s in the catalog on page 44.

Source Authenticity: OEM Print, Not a Third-Party Rework

This is a direct scan of the Howo factory parts catalog, not a recompiled list from a supplier. The page numbers, the part number formatting, and the exploded‑view drawings match what the Howo dealer uses. The original file name—HOWO_WD615_Parts_Catalog_ru-89514016371.pdf—suggests it originally came from a Russian-language distribution, but the part numbers are universal. If you’ve ever been burned by an aftermarket “OEM” catalog that leaves out the fastener torque tables, you’ll appreciate that this 354‑page document includes the torque specifications for every threaded fastener in the assembly drawings.

For hydraulic wear items, Futura FC200-FC400 Parts Catalog – OEM Wear Parts Specs follows the same factory approach.

Who Needs This Catalog?

If you’re a shop that works on Chinese‑built dump trucks, concrete mixers, or semi tractors with the Howo WD615, you need this. Same if you’re a fleet owner who stocks your own parts. The catalog saves you from ordering a water pump that doesn’t align with the fan hub or a brake chamber that has the wrong pushrod length. It’s also useful for the DIY guy who bought a surplus Howo truck and wants to overhaul it at home—but don’t expect a service manual. This is a parts catalog, not a repair procedure guide. You get part numbers, quantities, and exploded views. The step‑by‑step wrenching is on you.

FAQ – Howo WD615 Parts Catalog

Does this catalog include torque specs for the cylinder head?

Yes. Every major fastener in the exploded views has a torque value callout. Page 67 lists the cylinder head bolt torque sequence and final angle.

Is this catalog in English?

The part numbers and drawings are language‑agnostic. The text labels are in Russian but the numeric part numbers and torque values are universal. If you can read an exploded view, you can use this catalog.

Will this work for a 2005 Howo 8×4 dump truck with the WD615?

Yes. The catalog covers the WD615 engine across multiple chassis configurations including the 8×4 dump truck. Check the engine serial number range listed in the front of the catalog to confirm your revision. For 2005 models, the part numbers for the cylinder head and injection pump are correct.

How many pages are there and does it cover the entire truck or just the engine?

354 pages. It covers the entire vehicle: engine, cooling, fuel, driveline, brakes, steering, suspension, cab, electrical system. The engine section is about 90 pages; the rest is chassis and body parts.
