Product Features

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

• Performance: Withstands extreme dynamic loads and torsional forces, maintaining dimensional stability even under high RPM operation. The journal surfaces are hardened and polished for excellent wear resistance and low friction.

• Design: Fully interchangeable with the original equipment crankshaft, ensuring a perfect fit and alignment with the cylinder block and connecting rods.

Core Function

• Converts the linear motion of the pistons into rotational torque to drive the vehicle’s transmission and accessories.

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

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

Key Features and Buyer Benefits

Engineered for Durability Under Extreme Loads

• High-Strength Forged Steel Construction — Manufactured from 42CrMo alloy steel, quenched and tempered to achieve optimal hardness (HRC 58-62 on journal surfaces) while maintaining core toughness against torsional fatigue.
• Precision-Ground Journals — Main and rod journals are ground to Ra ≤ 0.4μm surface roughness, minimizing friction losses and extending bearing service life by up to 30%.
• Nitrided Surface Treatment — Fillet rolling and nitriding processes increase fatigue strength by over 25%, resisting crack initiation even under sustained high-RPM operation.
• Dynamic Balancing — Each crankshaft undergoes computerized dynamic balancing to within ≤ 15 g·cm residual imbalance, reducing vibration-induced wear on bearings and seals.
• OEM Dimensional Compliance — Manufactured to match ShangChai original specifications, ensuring zero-modification installation into the engine block.

Business Benefits for Procurement Managers

• Factory-Direct Pricing — Eliminate middleman markups. METTLEAD supplies directly from production facilities, delivering 20-35% cost savings versus aftermarket distributors.
• Reduced Downtime — Ready-to-ship inventory and fast logistics mean your engines return to service faster.
• White-Label Packaging Available — Protect your brand identity with custom packaging and labeling at no excessive premium.
• Strict Quality Control — 100% dimensional inspection, hardness testing, and magnetic particle flaw detection on every unit before dispatch.

Frequently Asked Questions — Crankshaft S00003155+01

What engines does the Crankshaft S00003155+01 fit?

This crankshaft is designed for the ShangChai SC9D and SC8DT series inline-6 diesel engines. It matches the original OEM dimensional specifications, so it installs without any machining or modification to the engine block.

Is this crankshaft forged or cast?

It is forged from 42CrMo alloy steel — not cast. Forging produces a denser grain structure with superior fatigue resistance, which is critical for a component that endures millions of stress cycles over its service life.

What quality inspections are performed before shipping?

Every crankshaft passes through a multi-stage inspection protocol: dimensional verification on all journals and thrust faces, Rockwell hardness testing, magnetic particle inspection (MPI) for subsurface cracks, and computerized dynamic balancing. Units that fail any checkpoint are rejected.

Can I use this crankshaft with standard-size bearings?

Yes. The Crankshaft S00003155+01 is manufactured to standard (STD) journal dimensions. It pairs directly with standard main bearings and connecting rod bearings. If your engine block has been line-bored or journals require undersizing, please specify when ordering.

How should I store this crankshaft before installation?

Store in a dry, temperature-stable environment. The crankshaft ships with anti-rust oil coating on all machined surfaces. Keep the protective wrapping intact until installation day, and avoid stacking heavy objects on top to prevent journal surface damage.

What is the expected service life of this crankshaft?

Under normal operating conditions with proper lubrication and maintenance intervals, this crankshaft is engineered to match OEM service life — typically 500,000 to 800,000 km before requiring inspection for wear limits. Actual longevity depends on engine load profiles, oil quality, and maintenance discipline.
