Product Features

• Structure: Forged from high-strength alloy steel, with precision-machined journals and crankpins. It features a fully balanced design with counterweights to reduce vibration.

• Performance: Heat-treated for high fatigue strength and wear resistance, with a nitride surface coating on journals for enhanced durability under high loads.

• Design: Optimized for the MC13 engine’s high torque output, with oil passages for continuous lubrication of journals and connecting rod bearings.

Core Function

• Converts the reciprocating motion of the pistons into rotational power, which drives the vehicle’s transmission and auxiliary systems.

• Maintains precise balance to minimize engine vibration, improving driving comfort and reducing wear on other components.

• Transmits power efficiently while withstanding the high mechanical stresses of heavy-duty operation.

The Crankshaft MC13 201-02101-0632 is the beating heart of your SINOTRUK MC13 engine — engineered to convert reciprocating piston motion into reliable rotational force that powers heavy-duty operations across thousands of kilometers. Sourced directly from our factory supply chain, this crankshaft delivers OEM-grade precision, exceptional fatigue resistance, and the exact dimensional tolerances your MC13 engine demands. When downtime costs you money, this is the component that keeps your fleet moving.

Key Features and Benefits of Crankshaft MC13 201-02101-0632

Precision-Engineered Performance

This SINOTRUK crankshaft is forged from high-strength alloy steel using advanced CNC machining processes. Every journal surface is ground to micro-level tolerances, ensuring smooth bearing contact, minimal vibration, and extended service life even under extreme torque loads.

• Superior Fatigue Strength: Forged steel construction with fillet rolling treatment resists cracking under cyclic stress — built to endure millions of combustion cycles without failure.
• OEM Dimensional Accuracy: Matches original SINOTRUK specifications for main journal diameter, rod journal diameter, stroke, and counterweight balance — no modifications needed during installation.
• Optimized Dynamic Balance: Precision-balanced counterweights reduce torsional vibration, protecting your bearings, flywheel, and transmission components from premature wear.
• Hardened Journal Surfaces: Induction-hardened bearing surfaces deliver outstanding wear resistance and maintain oil film integrity across all operating temperatures.
• Direct Replacement: Drop-in fitment for MC13 series engines — minimizes workshop time and gets your trucks back on the road faster.

Application Scenarios

Compatible Vehicle Models

• SINOTRUK SITRAK C7H (MC13 engine configuration)
• SINOTRUK SITRAK G7 heavy-duty tractor
• SINOTRUK HOWO T7H long-haul logistics truck
• SINOTRUK HOWO A7 heavy-duty dump truck (MC13 variant)
• Other SINOTRUK platforms equipped with the MAN-technology MC13 engine

System Function and Purpose

The crankshaft sits at the core of the engine’s crank-connecting rod mechanism — the primary power conversion system. It receives downward force from the pistons via connecting rods and transforms that linear motion into rotational torque delivered to the flywheel and drivetrain. In the MC13 engine, this crankshaft also drives the oil pump, coolant pump, and auxiliary systems through its front-end gear train. A failed or worn crankshaft leads to catastrophic engine damage, bearing knock, loss of oil pressure, and complete vehicle immobilization.

Frequently Asked Questions – Crankshaft MC13 201-02101-0632

Q1: Is this crankshaft an original OEM part or aftermarket?

This Crankshaft MC13 201-02101-0632 is manufactured to OEM specifications using the same forged alloy steel material and machining tolerances as the original SINOTRUK factory part. It serves as a direct replacement with identical fitment, hardness, and balance characteristics.

Q2: How do I verify this crankshaft fits my specific MC13 engine?

Confirm your engine nameplate shows the MC13 series designation and cross-reference part number 201-02101-0632 with your existing crankshaft. If your engine produces between 360–540 HP and uses a 156 mm stroke, this crankshaft is your match. Our team can also verify compatibility if you provide your engine serial number.

Q3: What quality inspections does this crankshaft pass before shipping?

Each unit undergoes a multi-stage inspection process: raw forging material certification, CNC dimensional measurement of all journals, magnetic particle testing for subsurface cracks, surface roughness verification, and final dynamic balance testing. Only crankshafts that pass every checkpoint leave our warehouse.

Q4: What is the expected service life of this crankshaft?

Under normal operating conditions with proper lubrication and regular oil changes, this crankshaft is designed to last the full engine overhaul interval — typically 500,000 to 800,000 km depending on load conditions and maintenance practices.

Q5: Can I order this crankshaft with custom packaging or without SINOTRUK branding?

Yes. We offer white-label and custom packaging options. Whether you need neutral boxes, your own brand labels, or specific crate dimensions for container optimization, we accommodate your requirements.

Q6: What other MC13 engine components can I source together with this crankshaft?

We supply the complete MC13 engine rebuild kit including main bearings, connecting rod bearings, pistons, piston rings, cylinder liners, camshaft, oil pump, water pump, gasket sets, and more. Bundling components in a single order reduces your shipping costs and simplifies procurement. Browse our full SINOTRUK engine parts catalog for details.
