Product Introduction: A precision-engineered bi-metal bearing made of a steel backing with a lead-tin alloy overlay. It features a lubrication hole for continuous oil flow, reducing friction and wear between the connecting rod and crankshaft journal. The bearing is designed to fit precisely into the connecting rod big end, ensuring proper alignment and load distribution.

Function: Supports the connecting rod and reduces friction during high-speed rotation of the crankshaft, ensuring smooth power transmission within the engine. The lubrication system dissipates heat and prevents premature wear, while the bi-metal construction provides high load capacity and durability under extreme engine conditions.

Camshaft VG1246050038 for SINOTRUK HOWO Engine – OEM Precision Timing Component

The Camshaft VG1246050038 is a critical engine timing component engineered specifically for SINOTRUK HOWO heavy-duty truck engines. Manufactured from high-strength alloy steel with precision-ground cam lobes and a heat-treated surface, this camshaft delivers exceptional wear resistance and accurate valve timing throughout its service life. Its lightweight, hollow-core design with strategically placed cutouts reduces rotational inertia, enabling smoother high-RPM operation and improved fuel efficiency in demanding commercial transport applications.

At JINAN METTLEAD AUTO SALES CO., LTD., we supply this genuine-spec camshaft directly from China’s manufacturing base, ensuring factory-direct pricing without compromising on the strict quality control that SINOTRUK HOWO engines demand. Whether you’re a fleet maintenance engineer or a parts distributor, this component is built to keep your heavy-duty trucks running at peak performance.

Key Features and Benefits of Camshaft VG1246050038

Superior Material Engineering

Forged from premium alloy steel (typically 20CrMnTi or equivalent), the VG1246050038 camshaft undergoes carburizing and quenching heat treatment to achieve a surface hardness of HRC 58–62. This ensures the cam lobes resist pitting, scuffing, and premature wear even under extreme cylinder pressures and high operating temperatures typical of HOWO diesel engines.

Precision-Ground Cam Profile

Each cam lobe is CNC-ground to micron-level tolerances, guaranteeing accurate valve lift, duration, and timing. This precision meshing with the engine’s timing gear train translates directly into optimized combustion efficiency, reduced emissions, and consistent power delivery across the engine’s operating range.

Weight-Optimized Hollow Design

The hollow-core construction with engineered cutouts reduces the camshaft’s rotational mass by approximately 15–20% compared to solid designs. Lower rotational inertia means faster engine response, reduced parasitic losses on the timing drive system, and less stress on camshaft bearings during rapid speed changes.

Direct OEM Fitment

Designed as a direct replacement for the original SINOTRUK HOWO part number VG1246050038, this camshaft requires no modifications for installation. Journal diameters, cam spacing, keyway dimensions, and drive gear interface all match factory specifications precisely.

Application Scenarios for Camshaft VG1246050038

This camshaft serves as the heartbeat of the SINOTRUK HOWO engine’s valve train system. Here are the primary scenarios where this component is essential:

• Fleet Overhaul Programs: When heavy-duty HOWO trucks reach 400,000–600,000 km intervals, camshaft replacement is a standard part of major engine overhauls. The VG1246050038 restores factory valve timing precision and eliminates power loss caused by worn cam profiles.
• Premature Wear Replacement: Contaminated oil, overheating events, or timing gear failures can damage camshaft surfaces. This component provides a cost-effective, OEM-spec replacement that restores engine performance without requiring a complete engine rebuild.
• Engine Assembly and Remanufacturing: Remanufacturing facilities and engine assembly plants rely on consistent, high-quality camshafts to build reliable powertrains. Our strict dimensional inspection ensures every unit meets assembly-line tolerances.
• Parts Distribution Inventory: Distributors serving African, Southeast Asian, Middle Eastern, and South American markets—where SINOTRUK HOWO trucks dominate heavy transport—maintain this part as a high-demand inventory item.

Frequently Asked Questions – Camshaft VG1246050038

What engines does the VG1246050038 camshaft fit?

This camshaft is designed for SINOTRUK HOWO trucks equipped with WD615, WD618, and WP10 series inline 6-cylinder diesel engines. Always cross-reference your engine nameplate data and existing part number to confirm compatibility before ordering.

How can I verify this camshaft matches my original part?

Compare the OEM number VG1246050038 stamped on your existing camshaft. Additionally, measure journal diameters, overall length, and cam lobe count (12 lobes for 6-cylinder). We can provide detailed dimensional drawings upon request for pre-purchase verification.

What is the expected service life of this camshaft?

Under normal operating conditions with proper lubrication and clean oil maintenance, this camshaft is engineered to last 500,000+ km. Premature failure is typically caused by oil starvation, coolant contamination in the oil system, or incorrect timing gear installation creating excessive load.

Does the camshaft come with the timing gear pre-installed?

No. The camshaft VG1246050038 is supplied as the shaft assembly only. The timing gear, thrust plate, and associated hardware should be ordered separately or reused from the original assembly if they pass inspection criteria.

What causes camshaft failure in HOWO engines?

The most common failure modes include: lobe surface pitting from abrasive particles in degraded oil, journal seizure from oil pump failure or blocked oil galleries, and fracture from incorrect timing gear backlash creating cyclic overload. Regular oil analysis and adherence to SINOTRUK maintenance intervals prevent most failures.

Can I order a sample before committing to bulk quantities?

Yes. We encourage technical evaluation before volume orders. Sample units are available with full dimensional inspection reports so your engineering team can verify fitment and quality standards independently.
