Product Features

• Structure: Precision-machined from high-strength, wear-resistant alloy steel, with external gear teeth and an internal splined bore for direct drive.

• Performance: The hardened steel construction resists wear and fatigue, ensuring consistent oil pressure delivery across all engine speeds. The precision-machined teeth ensure smooth meshing with the inner rotor for efficient oil pumping.

• Design: Factory-calibrated to match the original oil pump’s internal tolerances, ensuring a perfect fit and optimal flow rate.

Core Function

• Works in conjunction with the inner rotor to create a positive displacement pumping action, drawing oil from the pan and pressurizing it for the engine’s lubrication system.

• The meshing of the outer and inner rotors creates expanding and contracting chambers that move oil through the pump, maintaining stable pressure.

• The splined bore directly connects to the pump drive shaft, ensuring synchronized and reliable operation.

Key Features and Benefits of Outer Rotor-Oil Pump 200V05104-0251

Precision-Engineered Performance

The Outer Rotor-Oil Pump 200V05104-0251 is manufactured using high-grade powder metallurgy steel, delivering exceptional dimensional accuracy (tolerance within ±0.01mm). This precision ensures optimal meshing with the inner rotor, maintaining stable oil pressure across varying engine speeds from idle to full load.

Extended Service Life

Surface-hardened through advanced heat treatment processes, this outer rotor achieves a hardness rating of HRC 55-62. It resists abrasive wear from contaminated oil particles and withstands thermal cycling without deformation — typically lasting 300,000+ km under normal operating conditions.

Seamless OEM Compatibility

Designed as a direct drop-in replacement for the original SINOTRUK part number 200V05104-0251, this outer rotor requires zero modifications during installation. Every unit undergoes 100% dimensional inspection to guarantee perfect fitment with your existing oil pump assembly.

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

The Outer Rotor-Oil Pump 200V05104-0251 serves as the heart of the engine lubrication system in the following SINOTRUK vehicle platforms:

• SINOTRUK SITRAK C7H — Long-haul logistics tractors operating 200,000+ km/year on highway corridors across Africa, Southeast Asia, and Central Asia
• SINOTRUK HOWO T7H — Heavy-duty freight trucks handling 40-ton payloads in mining and construction environments
• SINOTRUK SITRAK G7 — Regional distribution trucks requiring consistent oil pressure during frequent stop-start urban cycles
• SINOTRUK HOWO A7 — Equipped with MC-series engines where this rotor maintains lubrication integrity at elevated ambient temperatures (45°C+)

In these demanding scenarios, the outer rotor maintains consistent volumetric efficiency above 92%, ensuring every bearing, piston, and camshaft receives adequate lubrication — even when operating in extreme heat, high altitude, or dusty conditions typical of emerging market routes.

Frequently Asked Questions — Outer Rotor-Oil Pump 200V05104-0251

What causes an outer rotor oil pump to fail in SINOTRUK MC-series engines?

The most common failure modes include abrasive wear from contaminated engine oil (poor filtration maintenance), thermal distortion from overheating events, and cavitation damage from running low oil levels. The 200V05104-0251 outer rotor is heat-treated to resist these conditions, but regular oil and filter changes remain essential for maximum service life.

How do I verify that 200V05104-0251 is the correct outer rotor for my engine?

Cross-reference the part number stamped on your existing oil pump assembly housing or consult your SINOTRUK engine parts catalog for the MC11/MC13 lubrication system section. If you are unsure, send us your engine nameplate photo and VIN — our technical team will confirm compatibility within 24 hours.

What is the dimensional tolerance of this outer rotor, and why does it matter?

Our outer rotor holds ±0.01mm tolerance on all critical surfaces. This precision directly affects the tip clearance between the inner and outer rotor — too loose and oil pressure drops; too tight and the pump seizes. OEM-grade tolerance ensures your oil pump delivers rated pressure (350-500 kPa) consistently across the full RPM range.

Can I replace only the outer rotor, or must I replace the entire oil pump assembly?

In most cases, if the inner rotor and pump housing show no scoring or excessive wear (clearance still within 0.05-0.15mm), replacing only the outer rotor is a cost-effective repair. However, if the pump has run with metal debris contamination, we recommend replacing both rotors as a matched set to restore optimal clearances.

What is the minimum order quantity for the 200V05104-0251 outer rotor?

We offer flexible MOQs starting from as low as 10 pieces for initial trial orders. For white-label or custom packaging orders, the typical MOQ is 100 pieces. Volume pricing tiers are available for orders exceeding 500 units — reach out to our sales team for a tailored quotation.
