Camshaft 200-04400-6050 Sinotruk – Precision-Engineered OEM Replacement for Heavy-Duty Diesel Engines

When your Sinotruk engine demands uncompromising valve timing accuracy, the Camshaft 200-04400-6050 delivers exactly that. Manufactured from high-strength alloy steel and precision-ground to OEM tolerances, this camshaft ensures optimal intake and exhaust valve lift, duration, and timing across thousands of operating hours. Trusted by fleet operators and engine rebuilders across Africa, Southeast Asia, the Middle East, and South America, it's the component that keeps your HOWO and SITRAK trucks running at peak thermal efficiency — load after load, mile after mile.

At JINAN METTLEAD AUTO SALES CO., LTD., we supply this camshaft directly from certified production lines in China, eliminating middlemen and delivering factory-direct pricing with full traceability. Whether you're sourcing for a single engine overhaul or stocking a regional parts warehouse, we provide the quality assurance, competitive pricing, and rapid logistics that procurement managers rely on.

Key Features and Benefits of Camshaft 200-04400-6050

Precision Cam Lobe Profiling

Each cam lobe is CNC-ground and polished to achieve surface roughness values below Ra 0.4μm. This precision profiling ensures consistent valve lift of ±0.02mm across all cylinders, translating directly into balanced combustion, reduced fuel consumption, and lower exhaust emissions. Your engine breathes exactly as the engineers intended.

Heat-Resistant Alloy Steel Construction

Forged from chromium-molybdenum alloy steel, this camshaft withstands continuous operating temperatures exceeding 300°C without deformation or fatigue cracking. The material's inherent toughness resists torsional stress generated by high-pressure common rail injection systems found in modern Sinotruk MC series engines.

Hardened Surface Treatment for Extended Service Life

A carburizing and quenching process achieves surface hardness of HRC 58–62 on all cam lobes and bearing journals. This hardened layer — typically 0.8–1.2mm deep — dramatically reduces adhesive wear and pitting, extending camshaft service life beyond 500,000 km under normal operating conditions.

Precision-Machined Bearing Journals

All bearing journals are ground to h6 tolerance class, ensuring optimal oil film formation within the cylinder head bearing saddles. Proper oil clearance (0.04–0.08mm) minimizes friction losses and prevents premature journal wear, protecting both the camshaft and the cylinder head.

Direct OEM Dimensional Compatibility

Part number 200-04400-6050 is manufactured to match original Sinotruk specifications without modification. Bolt patterns, journal diameters, cam phasing angles, and overall length are identical to the factory-installed component, ensuring drop-in fitment during engine overhaul or scheduled maintenance.

Application Scenarios for Camshaft 200-04400-6050

This camshaft serves as a critical valvetrain component in Sinotruk's MC-series inline-6 diesel engines, which power some of the most demanding heavy-duty applications on the road today. Here's where it performs:

• Long-Haul Logistics Fleets: HOWO T7H and SITRAK C7H tractors covering 200,000+ km annually require camshaft replacement during major overhauls at 500,000–600,000 km intervals. Fleet procurement managers stock this part to minimize vehicle downtime during scheduled engine rebuilds.
• Construction and Mining Operations: HOWO dump trucks and mixer trucks operating under extreme load and thermal stress in African and Middle Eastern mining sites experience accelerated valvetrain wear. This camshaft restores factory-spec valve timing after prolonged high-RPM, high-temperature operation.
• Regional Distribution Vehicles: Medium-distance cargo trucks in Southeast Asian markets accumulate mileage rapidly on variable-quality roads. Engine rebuilders in these regions rely on competitively priced, OEM-quality camshafts to keep repair costs manageable for owner-operators.
• Engine Remanufacturing Workshops: Professional engine rebuilders sourcing components for Sinotruk MC11/MC13 remanufactured engines require parts that meet original dimensional and metallurgical specifications without exception.

Frequently Asked Questions – Camshaft 200-04400-6050

What engines does the Camshaft 200-04400-6050 fit?

This camshaft is designed for Sinotruk MC11 and MC13 series diesel engines, commonly installed in HOWO T7H, SITRAK C7H, and related heavy-duty truck platforms. Always verify your engine serial number against the OEM parts catalog to confirm compatibility before ordering.

How do I know if my camshaft needs replacement?

Common indicators include excessive valve lash that cannot be corrected by adjustment, visible pitting or scoring on cam lobe surfaces, unusual ticking or tapping noises from the cylinder head area, and loss of engine power due to reduced valve lift. During major overhauls (typically at 500,000+ km), camshaft inspection and measurement against wear limits is standard practice.

What is the surface hardness, and why does it matter?

The cam lobes and journals are hardened to HRC 58–62 through carburizing and quenching. This hardness level prevents adhesive and abrasive wear at the cam-to-follower interface, where contact pressures can exceed 1,000 MPa during engine operation. Insufficient hardness leads to rapid lobe wear, valve timing drift, and ultimately engine performance degradation.

Can this camshaft be installed without modifying other valvetrain components?

Yes. The 200-04400-6050 is a direct dimensional replacement for the original Sinotruk camshaft. No modifications to rocker arms, followers, valve bridges, or timing gear are required. However, we recommend replacing cam followers and checking valve springs during any camshaft replacement to ensure optimal valvetrain geometry and longevity.

What quality inspections are performed before shipping?

Each camshaft undergoes: dimensional verification on CMM equipment (journal diameters, lobe profiles, overall length), surface hardness testing (Rockwell C scale), magnetic particle inspection for cracks or inclusions, and visual inspection for surface finish quality. Batch inspection reports with measurement data can be provided upon request.

How should the camshaft be stored before installation?

Store in a dry, temperature-stable environment. The camshaft ships with a protective anti-corrosion oil coating — do not remove this coating until installation. Keep the part in its original packaging, stored horizontally on a flat surface to prevent bending or journal damage. Avoid stacking heavy items on top of the packaging.
