3415365 Lubricating Oil Pump Replacement Part As the power core of the engine lubrication system, this lubricating oil pump adopts a gear-driven rotary pump structure. It is machined from a high-strength alloy casting, offering structural advantages of compact size and light weight. Its design is fully compatible with the installation layout of Cummins B-series engines. Through precise gear meshing, it achieves efficient lubricant delivery and operates stably under extreme temperatures ranging from -30°C to 120°C, as well as in harsh conditions with high dust and vibration. Each unit undergoes a 30-minute no-load operation and pressure stability test prior to shipment, ensuring that flow output and pressure control meet original equipment manufacturer standards.

Commercial Vehicle Sector: Compatible with medium-duty trucks and cargo vehicles from brands like Dongfeng and Foton equipped with Cummins B-series engines, ensuring continuous engine lubrication during long-haul transportation. Proven through 1.2 million kilometers of operation without major repairs. Construction Machinery Sector: Widely used in excavators and loaders from brands like XCMG and Liugong, providing stable lubrication for engines like the 6B5.9 in heavy-duty conditions such as infrastructure projects and mining operations. Designed for environments with significant temperature fluctuations and high dust concentrations. Industrial Power Applications: Serving stationary generator sets and pump units, Cummins B Series engines prevent shutdown failures caused by insufficient lubrication through stable pressure control during continuous operation. Agricultural Machinery Applications: Designed for combine harvesters and tractors, these engines withstand dusty and bumpy field conditions, ensuring engine reliability during seasonal high-intensity operations. |

- OEM-level compatibility: Precisely matches the oil gallery layout and mounting interfaces of Cummins B-series engines, enabling direct replacement without modifications. This eliminates the issues of poor fitment and complicated installation associated with non-OEM parts. Installation requires only aligning the locating pins and bolt holes, using the original factory gasket for assembly. Single-person labor time can be controlled within 1.5 hours.
- Extreme Condition Tolerance: Featuring an alloy monoblock pump body and precision-ground gears, it withstands 120°C high-temperature oil washdown and 200 bar instantaneous pressure surges. In dusty, high-vibration environments like mining and construction sites, failure rates are reduced by 60% compared to standard cast iron pumps.
- Efficient Lubrication Assurance: Optimized rotor profile design enhances flow output linearity by 15%. Maintains a minimum operating pressure of 1.2 bar even at engine idle, preventing dry friction wear during cold starts and extending engine lifespan by over 20%.
- Full-cycle cost advantage: Priced at just 60%-70% of OEM components, it delivers an 8,000-hour service life (approximately one year). Backed by 24/7 after-sales support, emergency replacement parts arrive within 72 hours via DHL or other international couriers during failures, minimizing equipment downtime losses.

1. Which engine models are compatible?
Compatible with Cummins 6C8.3 and other B-series core models
2. How does it differ from OEM parts? What are the pricing advantages?
Core performance is identical (same gear transmission structure, pressure fluctuation ≤0.3 bar). Eliminates OEM brand premium, with unit price only 60%-70% of OEM cost. Includes 6-month warranty and supports 72-hour emergency replenishment to meet rapid equipment maintenance needs.
3. How to determine replacement is needed?
① Abnormal oil pressure: <1.2 bar at idle or >0.5 bar fluctuation during operation;
② Unusual operational noise: Engine emits “clunking” friction sounds that intensify with increased RPM;
③ Signs of lubrication failure: Rapid oil degradation or abnormal wear marks on critical components.
4. Special tools required? Can regular repair shops install it?
No special tools needed. Standard socket wrench, torque wrench + OEM gasket suffice. Skilled technicians at regular repair shops can complete installation within 1.5 hours. Directly fits OEM mounting holes without modifications.
5. What post-installation checks are required?
① Idle test: After starting, idle for 5 minutes with oil pressure stabilizing at 1.2-1.5 bar. ② Load test: Run at 70% rated RPM for 10 minutes, maintaining pressure between 2.5-4.0 bar. ③ Leak check: Shut down and let idle for 30 minutes; no oil seepage from the pump body or connections indicates pass.
6. Consequences of reverse installation? How to prevent it?
Consequences: Complete lubrication system failure, causing internal engine dry friction and potentially rendering components unusable. Prevention: Align pump body “IN (inlet)/OUT (outlet)” markings with engine oil passages. Reverse installation will cause noticeable binding—verify by manual rotation.
7. What to monitor daily? When to shut down?
Daily monitoring: Oil pressure (normal range 1.2-4.0 bar), oil temperature (≤120°C). Immediate shutdown required if: Pressure <1.0 bar or >4.5 bar, temperature exceeds 130°C, noticeable abnormal pump noise, or significant oil leakage.
8. How to start in -30℃ extreme cold?
The product can start directly at -30℃ without additional preheating. After starting, idle for 2-3 minutes until oil pressure rises above 1.2 bar before gradually increasing load to avoid dry friction during cold starts.
9. Causes and solutions for abnormal pump body noise?
A: ① Mechanical failure: Foreign objects lodged between gears or bearing wear → Disassemble pump to remove debris; replace worn bearings promptly. ② Installation issues: Insufficient bolt torque (loose/rattling noise) or misaligned gasket → Tighten bolts to standard torque of 18-22 N・m, or replace gasket and reassemble.
