12159765 Deutz Oil Pump

truck parts 12159765 Oil Pump for Deutz TD226B-6 / WP6G125E22 Engine

1. Product Function & Application

Core Role: Acts as the power source of the engine lubrication system, drawing oil from the oil pan, pressurizing it, and delivering a steady flow to key moving components including crankshafts, camshafts, bearings and piston rings. It achieves full lubrication, reduces friction and wear, and carries away residual heat from parts in operation.

Performance Impact:

Reliability: Maintains stable oil pressure across engine idle to full-load conditions, preventing dry friction and component seizure that could lead to severe engine failure.

Durability: Optimized oil flow design lowers hydraulic resistance and pump parasitic load, extending the service life of both the oil pump and the engine itself.

Adaptability: Ensures consistent lubrication during cold starts and high-temperature operation, adapting well to extreme working environments.

Applicable Scenarios: Suitable for construction machinery, heavy-duty trucks, stationary generator sets and agricultural equipment; exclusively matched to Deutz TD226B-6 and Weichai WP6G125E22 diesel engines.

2. Compatibility & OE Compliance

Applicable Engines: Dedicated to Deutz TD226B-6 series in-line 6-cylinder diesel engines and Weichai WP6G125E22 series engineering machinery-specific engines.

OE Reference Number: 12159765, fully compliant with Deutz and Weichai OEM technical specifications, enabling direct replacement of original oil pumps without any modification or adjustment.

Interchangeability: Directly interchangeable with genuine Deutz and Weichai oil pumps, as well as aftermarket parts with the same OE number for the above-mentioned engine models.

Matching Service: Provides free engine model verification service; customers can submit engine serial numbers or vehicle VIN codes to confirm 100% compatibility before ordering.

3. Material & Craftsmanship Advantages

Premium Material Selection:

Pump body and gears are made of high-strength ductile iron, featuring excellent wear resistance and impact resistance to cope with long-term high-load operation.

The pump shaft adopts alloy steel material with quenching and tempering treatment, enhancing surface hardness and fatigue resistance.

The pressure relief valve core undergoes nitriding treatment, ensuring accurate pressure control and no oil leakage during operation.

Precision Processing Technology:

Adopts precision machining processes to ensure optimal gear tooth profile and clearance, realizing efficient oil suction and delivery with low energy consumption.

The oil inlet and outlet ports are precision-calibrated to match the original engine lubrication pipeline interface, ensuring seamless connection and no oil leakage.

The pump body is coated with anti-rust electrophoretic paint, which can resist corrosion and rust in humid and dusty working environments, extending the product service life.

4. Quality Testing & Grade

Quality Grade: High-quality aftermarket part, equivalent to Deutz and Weichai OEM quality level, meeting the strict technical requirements of heavy-duty diesel engine lubrication systems.

Rigorous Testing Procedures:

Undergoes 100% dimensional inspection to ensure perfect matching with the engine block mounting position and no assembly interference.

Passes oil pressure and flow stability tests across the full engine speed range, with no abnormal pressure fluctuations or oil supply interruptions.

Goes through long-term continuous operation durability tests under full-load conditions, with no gear wear, oil leakage or performance degradation.

Passes low-temperature cold start tests to ensure normal oil supply in a short time at low temperatures, avoiding dry friction during startup.

Certifications & Traceability: Complies with ISO 9001:2015 quality management system and IATF 16949 automotive parts production standards. Each unit is marked with a unique batch number, enabling full-process tracking of raw material sources, processing links and test results.

5. Service Life & Application Advantages

Service Life Performance: Under normal operating conditions, it has a long service life, adapting to the high-intensity working requirements of heavy-duty trucks and engineering machinery. Even in continuous-operation generator sets or harsh construction site environments, it can maintain stable performance for a long time.

Core Application Advantages:

Stable Pressure Output: The optimized gear structure and precision pressure relief valve ensure consistent oil pressure, avoiding oil starvation during high-speed operation and excessive pressure during low-speed operation.

Low Wear & Tear: High-strength ductile iron gears and precision machining reduce gear tooth wear, significantly extending the service life compared to ordinary cast iron oil pumps.

Strong Contamination Resistance: With built-in anti-clogging design, it can adapt to working environments with high oil impurity content, reducing faults caused by oil contamination.

Fault Improvement Effect: Effectively solves common problems of ordinary oil pumps such as unstable pressure, oil leakage and premature gear wear, reducing engine maintenance downtime and overall operation costs.

6. Packaging & Protection

Packaging Options:

Neutral Packaging: Uses standard export cartons with shock-absorbing foam lining inside to fix the product, preventing collision and damage during transportation, suitable for cross-border bulk shipment.

Custom Packaging: Supports customized packaging with customer brand logo, product introduction and installation notes to meet personalized brand promotion needs.

Protection Measures: Each oil pump is wrapped with anti-rust plastic film before packaging, effectively isolating moisture and air, and preventing rust during storage and transportation.

7. After-sales Support & FAQs

Technical Support: Provides free professional installation guidance, oil pump pressure adjustment tutorials and lubrication system matching suggestions. Offers 24/7 online technical consultation to solve problems such as abnormal oil pressure and oil supply failures encountered by customers during use.
