Hino W04D Crankshaft (OEM 13411-1590)

Forged Durability: Hino W04D Crankshaft Replacement for Light Commercial Trucks

The Hino W04D 4.0L diesel engine is the reliable heart of the Hino Dutro and Toyota Dyna light truck series. Ruich Value supplies a premium Crankshaft Assembly (OEM: 13411-1590) engineered to extend the service life of these essential logistics vehicles. As a core component of our Commercial Truck Engine Components inventory, this crankshaft resolves the fatigue cracking issues often seen in high-mileage delivery trucks operating in demanding stop-start urban environments.

To ensure superior longevity compared to standard aftermarket parts, our W04D crankshafts are manufactured from high-tensile Forged Steel. This material choice provides significantly higher resistance to bending and torsional stress than cast iron alternatives. Combined with induction-hardened journals and precision fillet rolling, this main shaft restores factory-level performance and oil pressure to your W04D naturally aspirated or turbocharged engine.

Technician’s Note: Journal Radius Inspection

The W04D engine relies on a specific fillet radius at the journal corners to distribute stress. When installing this new 13411-1590 crankshaft, ensure you use bearings with the correct chamfer to clear this radius. Using bearings with insufficient chamfer can cause point-loading on the fillet, leading to rapid catastrophic failure. Always plastigauge the oil clearance to ensure it falls within the 0.04-0.08mm factory specification.

Technical FAQ: Hino W04D Crankshaft

Q: Is this crankshaft compatible with the W04C engine?

A: No. While the W04C and W04D are related, the W04D is a 4.0L engine with a longer stroke than the 3.8L W04C. The crankshafts have different throws and are not interchangeable. Please check your engine data plate.

Q: Does this crankshaft work for Turbo (W04D-TM) models?

A: Yes. Part number 13411-1590 is the heavy-duty forged version designed to withstand the higher cylinder pressures of the Turbocharged W04D-TM engine, making it an excellent upgrade for naturally aspirated versions as well.

Q: Does the crankshaft come with the gears?

A: Our Hino crankshafts are typically supplied as “Bare Shafts”. The front timing gear is a precision interference-fit component. If your original gear is damaged or worn, please request a new gear set when placing your order.
