Product Introduction

• Structure: A robust, gear-type pump with a cast-iron housing, precision-machined internal gears, and integrated pressure relief valve. It features multiple mounting points and oil passages, and a drive gear interface for power transmission from the engine crankshaft.

• Performance: Delivers a consistent, high-pressure oil supply (up to 8 bar) to lubricate critical components such as bearings, crankshafts, and camshafts. The integrated pressure relief valve ensures stable oil pressure across all engine operating conditions, preventing over-pressurization and system damage.

• Design: Directly interchangeable with original equipment pumps, engineered to match the engine’s lubrication system specifications for seamless integration and reliable performance.

Core Function

1. Pressure Generation: Converts mechanical power from the engine into hydraulic pressure to circulate oil through the lubrication system.

2. Lubrication Delivery: Supplies pressurized oil to all moving engine components, reducing friction, wear, and heat generation.

3. System Protection: The integrated pressure relief valve maintains optimal oil pressure, preventing damage to the pump, bearings, and other system components.

Key Features and Benefits of Oil Pump 612640060198

Precision-Engineered Lubrication Performance

The Oil Pump 612640060198 WEICHAI uses a gear-type positive displacement design that maintains stable oil pressure across the full RPM range. Every internal gear tooth is CNC-machined to micron-level tolerances, ensuring volumetric efficiency stays above 92% even after thousands of operating hours.

• Stable Oil Pressure Output: Maintains rated pressure of 0.35–0.55 MPa under varying engine speeds, protecting crankshaft bearings, camshaft journals, and turbocharger assemblies from oil starvation.
• High Flow Capacity: Delivers sufficient oil volume to meet the lubrication demands of WEICHAI WP12 and WP13 series engines operating in heavy-load, high-temperature conditions.
• Anti-Cavitation Design: Optimized suction port geometry reduces cavitation risk at high RPM, preventing pump body erosion and extending service intervals.
• Premium Material Construction: Pump gears manufactured from powder metallurgy alloy steel with surface hardening treatment (HRC 58-62), resisting abrasive wear from contaminated oil conditions.
• OEM-Matched Fitment: Direct bolt-on replacement with factory-identical mounting dimensions, oil port alignment, and drive gear engagement — zero modification required.
• Extended Drain Compatibility: Designed to perform reliably with extended oil drain intervals up to 60,000 km when paired with WEICHAI-approved synthetic lubricants.

Procurement Advantages

• Factory-Direct Pricing: Sourced directly from our manufacturing partners, eliminating middleman markups by 15–30% compared to regional distributors.
• Strict Quality Control: Every unit undergoes pressure testing, flow verification, and dimensional inspection before shipment — backed by full traceability records.
• Fast Lead Times: In-stock availability with standard shipping within 3–7 business days to major global ports.
• White-Label Packaging Available: Custom packaging and labeling options for distributors who need brand-neutral or private-label presentation.

Application Scenarios – Where This Oil Pump Performs

The Oil Pump 612640060198 WEICHAI is purpose-built for heavy commercial vehicles and industrial machinery powered by WEICHAI WP12 and WP13 engines. Here is where it earns its keep every single day:

• SINOTRUK HOWO A7 / T7H Tractors: Long-haul logistics operations requiring 24-hour continuous engine lubrication under full payload conditions across intercity highways.
• SHACMAN X3000 / F3000 Dump Trucks: Mining and construction sites where extreme dust ingestion and steep-grade climbing push engine oil demand to maximum levels.
• SITRAK C7H Heavy-Duty Tractors: International freight corridors where consistent oil pressure protects turbocharged engines during sustained high-speed cruising.
• WEICHAI-Powered Construction Machinery: Loaders, excavators, and generator sets operating under variable-load cycles that demand reliable oil flow during sudden RPM transitions.
• FOTON Auman EST Heavy Trucks: Cold-chain and bulk transport fleets where engines start in sub-zero conditions and the oil pump must prime quickly to prevent dry-start damage.

Whether your vehicles haul 40-ton loads across African highways or climb Andean mountain passes, this oil pump keeps the lubrication system performing exactly as WEICHAI engineered it to.

Customer Case Study: Oil Pump 612640060198 Solving Fleet Lubrication Failures

A fleet management company in East Africa operating 85 SINOTRUK HOWO tractors experienced recurring low oil pressure warnings across 12 vehicles within a 3-month window. Their maintenance team traced the root cause to degraded aftermarket oil pumps that failed to maintain rated pressure above 2,200 RPM — creating dangerous lubrication gaps during highway cruising speeds.

After sourcing the Oil Pump 612640060198 WEICHAI through METTLEAD Truck Parts, the client replaced all 12 faulty units and proactively swapped pumps on 8 additional high-mileage vehicles. The results spoke for themselves:

• Zero oil pressure warnings recorded across all 20 vehicles in the following 6-month monitoring period.
• Engine oil consumption dropped 18% on average, indicating improved sealing and reduced internal leakage within the pump assembly.
• Procurement cost reduced by 22% compared to their previous regional supplier — with faster delivery timelines from METTLEAD’s ready-stock inventory.
• Maintenance interval extended from 25,000 km to 40,000 km for oil pump inspection, freeing up workshop capacity for other service tasks.

The client has since standardized on METTLEAD as their primary source for all WEICHAI oil pump replacements and related engine lubrication components.

Frequently Asked Questions – Oil Pump 612640060198 WEICHAI

What engines does the Oil Pump 612640060198 WEICHAI fit?

This oil pump is designed specifically for WEICHAI WP12 and WP13 series diesel engines. It serves as a direct OEM replacement with identical mounting bolt patterns, oil port dimensions, and drive gear specifications — no modifications or adapter plates are needed during installation.

How does this oil pump maintain pressure under heavy engine loads?

The gear-type positive displacement design ensures that oil flow volume increases proportionally with engine speed. Combined with tight gear-to-housing clearances (controlled within 0.05 mm), the pump sustains 0.35–0.55 MPa pressure even under full-throttle, high-temperature operating conditions that would cause inferior pumps to lose efficiency.

What is the expected service life of Oil Pump 612640060198?

Under normal maintenance conditions — including regular oil changes with WEICHAI-approved lubricants and clean filter elements — this oil pump delivers reliable performance for 500,000 km or more. Severe-duty applications (mining, construction) may reduce this to approximately 350,000 km depending on dust exposure and oil cleanliness.

How can I verify this is a genuine OEM-specification oil pump?

Every Oil Pump 612640060198 shipped by METTLEAD includes dimensional inspection records, material hardness certificates, and pressure test results. The pump casting carries the OEM part number marking, and we provide full traceability documentation back to the production batch on request.

What are the signs that my current WEICHAI oil pump needs replacement?

Watch for these indicators: persistent low oil pressure warnings at operating temperature, unusual mechanical noise from the front engine timing cover area, metal particles in oil filter media during routine service, or oil pressure that drops below 0.25 MPa at idle speed. Any of these symptoms suggest internal gear wear has exceeded acceptable limits.

Can I order the Oil Pump 612640060198 with custom packaging for resale?

Yes. METTLEAD offers white-label and custom packaging services. You can specify your own brand name, part number labeling, barcode format, and box design. Minimum order quantities for custom packaging typically start at 50 units — contact our team for exact requirements.
