Product Features

• Structure: Precision-machined from high-strength alloy steel, with a hardened and ground surface to resist wear. It features a 10-tooth profile designed to mesh perfectly with the outer rotor of the oil pump.

• Performance: Rotates within the pump housing to create pressure and draw oil from the sump, delivering it to critical engine components. The hardened surface ensures long service life and resistance to abrasion from contaminants in the engine oil.

• Design: Factory-calibrated to match the original pump’s internal tolerances, ensuring perfect meshing with the outer rotor for efficient oil pumping.

Core Function

• Works in tandem with the outer rotor to generate oil pressure, ensuring a continuous flow of lubrication to the engine’s crankshaft, camshaft, and bearings.

• Maintains precise internal clearances to ensure optimal pump efficiency and consistent oil pressure across all engine operating speeds.

• The hardened surface resists wear, extending the service life of the oil pump and preventing premature failure due to component degradation.

Key Features and Benefits of Inner Rotor-Oil Pump 200V05104-0234

Precision-Engineered Performance

The inner rotor-oil pump 200V05104-0234 is manufactured using high-grade powder metallurgy technology, delivering exceptional dimensional accuracy (tolerance within ±0.01mm). This precision ensures optimal meshing with the outer rotor, maintaining stable oil flow rates across varying engine speeds from idle to full load.

Superior Material Durability

Crafted from wear-resistant sintered alloy steel, this inner rotor withstands the abrasive nature of engine oil contaminants and resists surface fatigue even after 500,000+ km of heavy-duty operation. The hardened tooth profile minimizes volumetric efficiency loss over the component’s service life.

OEM-Grade Fitment

Every unit is manufactured to match the exact dimensional and performance specifications of the original SINOTRUK part number 200V05104-0234. This guarantees drop-in installation without modifications — saving your customers costly workshop downtime.

Consistent Oil Pressure Delivery

The rotor geometry is optimized to maintain rated oil pressure output (0.3–0.5 MPa at operating temperature), protecting critical engine components including crankshaft bearings, camshaft journals, and piston cooling jets from premature wear.

Cost-Effective Procurement

As a factory-direct supplier, METTLEAD eliminates distribution markups. Bulk procurement programs and flexible MOQ arrangements make this inner rotor-oil pump an ideal choice for fleet maintenance operations and regional parts distributors seeking competitive margins.

Application Scenarios — Where This Inner Rotor-Oil Pump Works Hardest

The Inner Rotor-Oil Pump 200V05104-0234 is designed to serve across the full range of SINOTRUK heavy-duty applications where engine reliability is non-negotiable:

• SINOTRUK HOWO A7/T7H Long-Haul Tractors — Maintaining consistent oil pressure during 20+ hour continuous highway operations across Africa, Southeast Asia, and Middle Eastern corridors.
• SINOTRUK SITRAK C7H Premium Logistics Trucks — Supporting the MC11/MC13 engine platform in high-frequency start-stop urban distribution cycles where oil pump wear accelerates.
• SINOTRUK HOWO Mining Dump Trucks — Enduring extreme vibration, steep gradient loads, and dust-contaminated operating environments in open-pit mining operations.
• SINOTRUK Concrete Mixer Trucks — Delivering stable lubrication during prolonged idle periods and variable-load PTO-driven operations on construction sites.
• SINOTRUK HOWO Cargo Trucks (6×4, 8×4) — Protecting engine internals during overloaded conditions common in developing market freight operations.

Whether your fleet operates in the scorching heat of the Middle East or the freezing conditions of Central Asia, this inner rotor maintains its dimensional stability and oil delivery performance across the full -30°C to +150°C operating envelope.

Frequently Asked Questions — Inner Rotor-Oil Pump 200V05104-0234

What is the function of the inner rotor in an oil pump assembly?

The inner rotor-oil pump 200V05104-0234 is the driving component inside a gerotor-type oil pump. It meshes with the outer rotor to create expanding and contracting chambers that draw engine oil from the sump and deliver it under pressure to all lubrication points within the engine. A worn or damaged inner rotor leads to reduced oil pressure, accelerated bearing wear, and potential catastrophic engine failure.

How do I know when the inner rotor needs replacement?

Common indicators include low oil pressure warnings at idle, increased engine noise (particularly from the valve train or crankshaft area), and visible scoring or excessive clearance (beyond 0.15mm) between the inner and outer rotor during inspection. Preventive replacement is recommended during major engine overhauls or when oil pressure drops below manufacturer specifications.

Is this inner rotor compatible with all SINOTRUK engine models?

Part number 200V05104-0234 is specifically designed for SINOTRUK MC-series and D-series engines commonly found in HOWO, SITRAK, and related platforms. Always cross-reference your existing part number or consult our technical team to confirm fitment for your specific engine variant before ordering.

What is the expected service life of this inner rotor-oil pump component?

Under normal operating conditions with regular oil and filter changes, this inner rotor is engineered to deliver reliable performance for 400,000–600,000 km. Actual service life depends on oil quality, filtration maintenance, operating loads, and environmental conditions.

Can I order a complete oil pump assembly instead of just the inner rotor?

Yes. METTLEAD supplies both individual oil pump components (inner rotor, outer rotor, pump body, relief valve) and complete oil pump assemblies for SINOTRUK engines. Contact our team to discuss whether a rotor replacement or full assembly is more cost-effective for your application.

What packaging options are available for this part?

We offer three packaging tiers: METTLEAD branded packaging, neutral (unbranded) packaging for white-label resellers, and fully customized packaging with your company branding, part numbers, and barcodes. Anti-corrosion VCI wrapping is applied to all units regardless of outer packaging choice.
