Product Introduction: A high-strength alloy steel gear with precision-machined teeth and a heat-treated surface for wear resistance. It features a lightweight, hollow design with cutouts to reduce rotational inertia, and its teeth are precision-ground for accurate meshing with the engine’s timing gear train.

Function: Transmits rotational motion from the engine’s crankshaft gear to the camshaft, driving the valve train to open and close the intake/exhaust valves at the correct timing. The precision-tooth design ensures smooth power transmission, minimizing noise and vibration while maintaining reliable engine performance.

Camshaft Gear 200-04501-0191 SINOTRUK – Precision-Engineered Timing Gear for Heavy-Duty Diesel Engines

When your SINOTRUK engine demands flawless valve timing under extreme loads, the Camshaft Gear 200-04501-0191 delivers uncompromising precision. Manufactured from high-strength alloy steel and heat-treated to HRC 58–62 surface hardness, this camshaft gear is built to synchronize your engine’s timing gear train with micron-level accuracy — mile after mile, load after load. Sourced directly from our factory in China, it reaches your warehouse faster and at a fraction of aftermarket pricing, without sacrificing OEM-grade quality.

Key Features and Benefits of Camshaft Gear 200-04501-0191

Superior Material and Heat Treatment

Forged from premium alloy steel (20CrMnTi or equivalent), this SINOTRUK camshaft gear undergoes carburizing and quenching heat treatment. The result is a hardened tooth surface (HRC 58–62) that resists pitting, spalling, and abrasive wear — extending service life by up to 40% compared to standard carbon steel alternatives.

Precision-Ground Tooth Profile

Each tooth is CNC-ground to ISO Grade 6 accuracy, ensuring smooth, low-noise meshing with the crankshaft gear and idler gears. This precision eliminates timing drift and reduces harmonic vibration throughout the gear train, protecting adjacent components from premature fatigue.

Lightweight Hollow Design

Strategic cutouts and a hollow hub reduce rotational inertia by approximately 15–20% without compromising structural rigidity. Lower inertia means faster engine response and reduced parasitic energy loss — a measurable advantage in fuel-conscious fleet operations.

Direct OEM Replacement

Part number 200-04501-0191 is a direct-fit replacement for SINOTRUK MC11/MC13 series engines. No machining, no adapter plates, no guesswork — it bolts into your existing timing case with factory-spec tolerances.

Technical Specifications

Application Scenarios

The Camshaft Gear 200-04501-0191 SINOTRUK is engineered for demanding real-world environments where engine timing integrity is non-negotiable:

• Long-Haul Logistics Fleets: SINOTRUK HOWO T7H and SITRAK C7H tractors operating 200,000+ km annually require timing components that maintain accuracy across extended drain intervals and thermal cycling.
• Construction and Mining Operations: HOWO dump trucks and mixer trucks endure constant high-RPM, high-torque loads. A worn camshaft gear introduces valve timing errors that degrade power output and increase fuel consumption — this replacement restores factory performance.
• Engine Overhaul and Rebuild Workshops: Authorized and independent repair facilities performing MC11/MC13 engine rebuilds rely on this gear to meet OEM timing specifications without sourcing from expensive dealer channels.
• Aftermarket Parts Distributors: Wholesalers serving African, Southeast Asian, Middle Eastern, and CIS markets stock this high-demand part to fulfill fleet maintenance contracts with competitive lead times.

OEM/ODM Capability

JINAN METTLEAD AUTO SALES CO., LTD. supports flexible procurement models tailored to your business requirements:

• White-Label Packaging: Ship under your own brand with custom boxes, labels, and documentation — ideal for distributors building regional brand equity.
• Custom Packaging: Specify packaging dimensions, materials, and labeling languages to match your market’s regulatory and logistical requirements.
• Strict Quality Control: Every camshaft gear undergoes 100% dimensional inspection, surface hardness testing, and visual defect screening before dispatch.
• Factory-Direct Pricing: Eliminate middlemen. Our direct-from-source model delivers 20–35% cost savings versus traditional import channels.
• Bulk and Mixed-Container Orders: Combine this camshaft gear with other SINOTRUK HOWO engine parts in a single shipment to optimize freight costs.

Frequently Asked Questions

What causes a camshaft gear to fail in SINOTRUK MC11/MC13 engines?

The most common failure modes are tooth surface pitting (from inadequate lubrication or contaminated oil), excessive backlash from wear (leading to timing rattle), and root fracture from shock loads. Regular oil changes with OEM-spec lubricant and replacing the gear during major overhauls prevent catastrophic timing failure.

How do I verify that 200-04501-0191 fits my specific engine?

Cross-reference the part number stamped on your existing camshaft gear or consult your engine’s parts catalog by serial number. This gear is designed for SINOTRUK MC11 and MC13 series engines found in HOWO T7H, A7, and SITRAK C7H platforms. If uncertain, send us your engine nameplate photo and we will confirm compatibility within 24 hours.

What is the expected service life of this camshaft gear?

Under normal operating conditions with proper lubrication, this gear is engineered to match OEM service intervals — typically 500,000–800,000 km or the engine’s first major overhaul cycle. The carburized tooth surface and precision grinding ensure minimal wear accumulation over this lifespan.

Can I visually distinguish a worn camshaft gear from a serviceable one?

Yes. Inspect for visible pitting or micro-spalling on tooth flanks, polished wear marks on one side of the tooth (indicating misalignment), chipped tooth edges, and any discoloration from overheating. If backlash exceeds the service manual’s maximum specification (typically 0.05–0.15 mm), replacement is required.

Does this gear come with a timing mark for installation alignment?

Yes. The gear features a factory-stamped timing mark that must be aligned with the corresponding mark on the crankshaft gear during installation. Incorrect alignment will result in valve timing errors, loss of power, and potential piston-to-valve contact on interference engines.
