Product Introduction

• Structure: A forged steel crankshaft with precision-machined journals and crankpins, surface-hardened for wear resistance. It features an integrated gear at the rear for driving the camshaft and auxiliary systems.

• Performance: Transmits high torque loads with minimal deflection, ensuring smooth engine operation. The hardened surfaces and balanced design reduce vibration and extend service life under heavy-duty conditions.

• Design: Directly interchangeable with original equipment crankshafts, ensuring a perfect fit with the engine block, connecting rods, and bearings.

Core Function

1. Energy Conversion: Converts the up-and-down linear motion of the pistons into rotational motion, which drives the vehicle’s transmission and auxiliary systems.

2. Torque Transmission: Transmits the power generated by combustion to the flywheel and drivetrain, delivering the engine’s output torque.

3. Dynamic Balance: Precision balancing minimizes vibration and stress on engine components, ensuring smooth operation and long durability.

Key Features and Buyer Benefits

Precision-Forged Construction

This crankshaft is manufactured from high-strength forged steel, then heat-treated and micro-finished on all journal surfaces. The result is a component that resists fatigue cracking under continuous high-torque loads — exactly what long-haul and heavy-load applications require.

OEM Dimensional Accuracy

Every journal diameter, fillet radius, and counterweight profile matches WEICHAI’s original engineering drawings. That means drop-in fitment with no rework, reducing your workshop downtime and labor costs during engine rebuilds.

Dynamic Balancing

Each Crankshaft 1006574089 WEICHAI undergoes multi-plane dynamic balancing to minimize harmonic vibration. Lower vibration means extended bearing life, quieter engine operation, and fewer warranty claims flowing back to your service desk.

Corrosion-Resistant Surface Treatment

Journal surfaces receive anti-corrosion treatment that protects the crankshaft during extended storage and ocean freight — a practical advantage for international buyers managing longer supply-chain lead times.

Cost-Efficiency for Bulk Procurement

METTLEAD’s factory-direct model eliminates intermediary markups. Procurement managers gain access to tier-one pricing structures that protect margins while maintaining genuine component quality.

Technical Specifications

Application Scenarios – Vehicle and Engine Fitment

The Crankshaft 1006574089 WEICHAI is designed for installation in WEICHAI WP-series diesel engines commonly powering the following heavy-duty platforms:

• SINOTRUK HOWO T7H / A7 – Long-haul logistics tractors running WEICHAI WP12/WP13 powertrains
• SINOTRUK SITRAK C7H – Premium highway tractors demanding peak engine reliability over 1,000,000+ km service intervals
• SHACMAN X3000 / F3000 – Regional distribution and construction-site tippers requiring high-torque crankshaft durability
• FOTON Auman EST-A – Intelligent heavy trucks pairing WEICHAI engines for fuel-efficient freight corridors
• Construction & Mining Equipment – Stationary and mobile machinery powered by WEICHAI industrial diesel engines sharing the same crankshaft architecture

If your fleet operates any WEICHAI-powered platform and you’re planning scheduled overhauls, this crankshaft ensures your engines return to service at full OEM performance.

OEM / ODM Capability and Custom Packaging

White-Label Supply

METTLEAD offers white-label packaging for distributors who sell under their own brand. Your company logo, part numbers, and barcode labels are applied at the factory — products arrive shelf-ready for your warehouse.

Custom Packaging Options

Whether you require branded wooden crates, retail-style color boxes for counter sales, or bulk palletized shipments optimized for container loading, our packaging team adapts to your logistics requirements.

Strict Quality Control

Every Crankshaft 1006574089 WEICHAI passes through a multi-stage quality gate:

1. Raw material chemical composition verification
2. Forging process dimensional inspection
3. Post-heat-treatment hardness testing
4. 100% magnetic particle testing for subsurface defects
5. CMM (Coordinate Measuring Machine) final dimensional audit
6. Dynamic balance verification before packaging

This six-step protocol ensures that every crankshaft leaving our facility meets or exceeds original equipment standards — giving your customers zero-defect confidence.

Frequently Asked Questions – Crankshaft 1006574089 WEICHAI

What engines does Crankshaft 1006574089 WEICHAI fit?

This crankshaft is designed for WEICHAI WP-series heavy-duty diesel engines. It serves as a direct replacement in engines installed across SINOTRUK, SITRAK, SHACMAN, and FOTON platforms that specify part number 1006574089. Always cross-reference your engine’s nameplate data to confirm compatibility.

Is this crankshaft supplied at standard size or in undersize options?

Our standard supply is OEM nominal dimension. If you require undersize journal crankshafts (e.g., -0.25 mm or -0.50 mm for regrind situations), please specify this in your inquiry and we will confirm availability from current production batches.

How is the crankshaft protected during international shipping?

Each crankshaft receives a heavy anti-rust oil coating, followed by VCI (Volatile Corrosion Inhibitor) wrapping, then placement in a reinforced wooden export crate designed to withstand ocean freight handling. This triple-layer protection keeps the component pristine across 30–45 day sea voyages.

What quality certifications accompany each shipment?

Every batch ships with a material test certificate, hardness test report, dimensional inspection report, and magnetic particle testing clearance document. Additional certifications can be arranged upon request during order confirmation.

Can I order a sample crankshaft before committing to bulk quantity?

Yes. METTLEAD supports sample orders so you or your technical team can verify fitment, finish quality, and dimensional accuracy before scaling up. Sample lead times are typically shorter than bulk production runs.

What is the expected service life of this crankshaft under normal operating conditions?

When installed with correct bearing clearances and maintained with clean, properly graded engine oil, this crankshaft is engineered to match OEM service-life expectations — typically aligned with a major overhaul interval of 500,000 to 800,000 km depending on load profile and maintenance discipline.
