The 3415365 Lubricating Oil Pump is the power core of the engine lubrication system, featuring a gear-driven rotary pump structure. Machined from high-strength alloy casting, it offers a compact and lightweight design fully compatible with Cummins B-series engine layouts. Through precise gear meshing, it achieves efficient lubricant delivery even under extreme temperatures ranging from -30°C to 120°C and harsh conditions involving high dust and vibration. Each unit undergoes rigorous no-load and pressure stability testing to ensure performance meets original equipment manufacturer standards.

Commercial Vehicles
Compatible with medium-duty trucks and cargo vehicles equipped with B-series engines. Proven reliable for over 1.2 million kilometers of long-haul operation.
Construction Machinery
Widely used in excavators and loaders (e.g., 6B5.9 engines) for heavy-duty infrastructure and mining projects with high dust concentration.
Industrial Power
Serves stationary generator sets and pump units, providing stable pressure control during continuous 24/7 operations.
Agricultural Machinery
Designed for combine harvesters and tractors to withstand dusty and bumpy field conditions during seasonal high-intensity work.
- OEM-level Compatibility: Precisely matches oil gallery layouts and mounting interfaces for direct replacement without modifications. Align locating pins and bolt holes for assembly in under 1.5 hours.
- Extreme Condition Tolerance: Alloy monoblock body withstands 120°C oil and 200 bar pressure surges. Failure rates are reduced by 60% compared to standard pumps in mining environments.
- Efficient Lubrication Assurance: Optimized rotor design improves flow linearity by 15%, maintaining 1.2 bar pressure at idle to prevent dry friction during cold starts.
- Cost-Effective Reliability: Delivers an 8,000-hour service life at 60%-70% of the cost of branded components, backed by international logistics support for rapid replacement.

Frequently Asked Questions
1. Which engine models are compatible with part 3415365?
It is primarily compatible with Cummins 6C8.3 and other core B-series diesel engine models.
2. How does this replacement part compare to OEM parts in price and performance?
The performance is identical (gear transmission, pressure stability ≤0.3 bar), but the cost is only 60%-70% of the OEM brand price. It includes a 6-month warranty.
3. What are the signs that the oil pump needs replacement?
Look for abnormal oil pressure (<1.2 bar at idle), unusual "clunking" sounds that increase with RPM, or signs of rapid oil degradation and component wear.
4. Can regular repair shops install this pump?
Yes, no special tools are required. A standard socket wrench, torque wrench, and OEM gasket are sufficient for a 1.5-hour installation.
5. What checks should be performed after installation?
Run an idle test for 5 minutes (pressure 1.2-1.5 bar), followed by a load test at 70% RPM for 10 minutes (pressure 2.5-4.0 bar), and check for any leaks.
6. How does the pump perform in extreme cold (-30°C)?
The pump can start directly at -30°C without preheating. It is recommended to idle for 2-3 minutes until oil pressure stabilizes before increasing load.
