Product Features

• Structure: Forged from high-strength alloy steel, with precision-machined main journals and connecting rod journals. It features counterweights for balance, oil passages for lubrication, and keyways for timing gear installation.

• Performance: Withstands extreme dynamic loads and torsional forces, maintaining dimensional stability even under high RPM operation. The surface of the journals is hardened and polished to provide excellent wear resistance and a low-friction surface for the main bearings.

• Design: Directly interchangeable with the original equipment crankshaft, ensuring a perfect fit and precise alignment with the engine’s cylinder block and connecting rods.

Core Function

• Converts the linear motion of the pistons into rotational torque, which drives the vehicle’s transmission and other accessories.

• Distributes engine oil to the main bearings and connecting rod bearings through internal oil passages, ensuring continuous lubrication and heat dissipation.

• The integrated counterweights balance the rotating and reciprocating forces, reducing engine vibration and improving overall smoothness.

Crankshaft D09-101-40+B ShangChai – Premium Engine Crankshaft for Heavy-Duty Truck Applications

The crankshaft is the beating heart of any diesel engine — it converts raw combustion force into the rotational power that moves thousands of tons down the highway. The Crankshaft D09-101-40+B, engineered for ShangChai D9 series engines, delivers uncompromising durability and precision balance for heavy-duty commercial vehicles operating under extreme loads. Sourced directly from METTLEAD Truck Parts’ quality-controlled supply chain in China, this crankshaft arrives at your warehouse faster, priced sharper, and built to the exact OEM dimensional tolerances your fleet demands.

Key Features and Benefits of the Crankshaft D09-101-40+B ShangChai

Engineered for Endurance

This ShangChai crankshaft is forged from high-strength alloy steel, then precision-machined and dynamically balanced to withstand the punishing combustion cycles of a D9 diesel engine. Every journal surface is induction-hardened to resist wear, ensuring consistent oil film retention across hundreds of thousands of kilometers.

• OEM-Grade Dimensional Accuracy — Main journal and rod journal diameters hold tolerances within ±0.01 mm, guaranteeing seamless fitment without costly machining at installation.
• Superior Fatigue Resistance — Fillet rolling on all journal radii increases fatigue life by up to 200%, reducing the risk of catastrophic crankshaft failure under sustained high-torque operation.
• Dynamic Balancing — Each crankshaft is individually balanced to minimize torsional vibration, protecting main bearings and extending overall engine service life.
• Corrosion-Resistant Finish — Anti-rust surface treatment protects the crankshaft during shipping and storage, so it arrives ready to install.
• Factory-Direct Pricing — By eliminating middlemen, METTLEAD delivers this crankshaft at a cost structure that strengthens your procurement margins.

Frequently Asked Questions – Crankshaft D09-101-40+B ShangChai

What engines does the Crankshaft D09-101-40+B fit?

This crankshaft is specifically manufactured for the ShangChai (SDEC) D9 series inline-6 diesel engines, including the SC9D, SC9DK, and related variants. Always verify your engine nameplate data against the part number D09-101-40+B before ordering to confirm compatibility.

Is this crankshaft a direct OEM replacement?

Yes. The Crankshaft D09-101-40+B is manufactured to OEM dimensional specifications and tolerances. It installs directly into the engine block without additional machining, provided the main bearing saddles and connecting rods are within service limits.

What material is the crankshaft made from?

It is forged from 42CrMoA alloy steel (or equivalent grade), which provides an excellent balance of tensile strength, fatigue resistance, and machinability. Journal surfaces are induction-hardened to HRC 55–62 for maximum wear resistance.

How is the crankshaft quality verified before shipment?

Each unit undergoes a multi-stage inspection process: dimensional measurement of all journals and thrust faces, magnetic particle inspection (MPI) for subsurface crack detection, surface roughness verification, and individual dynamic balancing. Certificates of conformance are available on request.

Can I order undersized or oversized crankshafts for engine rebuilds?

METTLEAD can supply crankshafts with undersize journal dimensions (e.g., -0.25 mm, -0.50 mm) for engines requiring re-machined bearing saddles. Please specify your required journal size when submitting your inquiry.

What is the typical lead time for this crankshaft?

For standard stock items, shipment is arranged within 3–5 business days after payment confirmation. Custom or bulk orders may require 15–25 days depending on quantity and any special requirements.

How is the crankshaft packaged for international shipping?

The crankshaft is coated with anti-rust oil, wrapped in VCI (Vapor Corrosion Inhibitor) film, and secured inside a reinforced wooden crate designed to withstand ocean freight handling. This ensures it arrives in perfect condition regardless of transit duration.
