612600060726 WD615 Water Pump

612600060726 is an exclusive water pump for WD615 series engines, the core power component of the engine cooling system. Driven by a belt, it rotates the impeller at high speed to force coolant circulation, transferring heat from the cylinder block and head to the radiator for cooling, maintaining the engine's normal operating temperature (85-95℃). Suitable for heavy-duty long-haul, mining and engineering operations, it resists high temperatures, high speeds and long continuous operation, preventing fatal faults like overheating, cylinder scuffing and bearing seizure, ensuring stable power output and prolonged engine life.

Applicable Vehicles: SHACMAN Delong X3000/F3000/Aolong, SINOTRUK Steyr/Howo and other heavy-duty trucks & engineering vehicles (tractors, dump trucks, mixers) equipped with WD615 series diesel engines.

Adaptable Systems: Original WD615 engine cooling system, compatible with same-spec pipelines, pulleys and tensioning mechanisms.

OE Reference Number: 612600060726

Rated Bearing Life: ≥2000 hours.

Overall Weight: 4.8kg.

Installation Dimensions: Pump body flange aperture Φ110mm, bolt hole distribution circle Φ130mm (fixed with 4-M12 bolts).

Core Materials

Pump body: High-strength cast iron (HT250), heat-resistant, vibration-resistant and wear-resistant. Impeller: Cast aluminum (ZL104), lightweight and corrosion-resistant. Bearing: High-carbon chromium steel (GCr15) for high speeds. Mechanical seal: Silicon carbide + graphite, excellent temp resistance and sealing. Shaft: 45# quenched and tempered steel, high torsional strength and deformation resistance.

Surface Treatment

Pump body: Anti-rust spray painting (96h salt spray resistance). Impeller: Anodized for enhanced coolant corrosion resistance. Pump shaft: Chrome-plated for wear and rust resistance. Flange sealing surface: Precision ground for tight fit and leak prevention.

Production Process

Pump body: Precision casting to reduce internal defects. Impeller: CNC-machined (unbalance ≤5g·cm) for dynamic balance. Mechanical seal: Cold-pressed for uniform gap. Bearing and shaft: Interference fit press-fitting for stability. 100% factory testing (water pressure sealing, idle noise, flow) before delivery.

Production Line Capacity

Equipped with exclusive molds, automatic assembly lines and precision testing equipment, monthly output ≥10,000 units, supporting flexible bulk order delivery.

Quality Grade: High-quality after-sales parts, meeting WD615 OE standards, bench-tested and interchangeable with original parts.

Inspection Items: Water pressure sealing, coolant flow, high-speed idle, noise, high-low temp cycle, bearing clearance and dimension accuracy tests.

Quality System: Certified by both IATF16949 automotive industry quality system and ISO9001 general quality system, with full compliance control of the production process.

Batch Tracking: Laser-coded OE number, batch number and production date; 3+ years of records for full-batch traceability.

Average Service Life: ≥4 years (or 350,000 kilometers, matching the regular maintenance cycle of WD615 engine).

Performance Improvement: Silicon carbide + graphite seal reduces leakage by 90% and doubles seal life; precision balanced impeller (≤60dB) reduces noise and bearing wear; HT250 pump body resists vibration/cracking; pre-injected high-temp grease ensures long maintenance-free bearing life.

Harsh Environment Adaptation: -40℃ cold-start capability (no jamming/seal brittle fracture); 135℃ high-temp stability (no leakage); excellent rust/corrosion resistance for desert and coastal areas, avoiding sand/rust-induced faults.

Common Fault Improvement

Targets common original pump faults: coolant leakage, bearing noise, impeller corrosion, flow attenuation and seal aging. Upgraded materials and structure eliminate high-intensity operation vulnerabilities, reducing fault rates.

Maintenance Value

Direct in-situ replacement (no hole modification/pipeline adjustment), cutting maintenance time by 50%. Long service life matches engine maintenance cycles, reducing replacements. Stable performance prevents overheating damage, lowering overhaul costs and ensuring vehicle attendance.

Packaging Configuration

Three-layer packaging: Plastic film (moisture-proof) + EVA foam (shock-absorbing) + thickened corrugated carton. Desiccants included; water inlets/outlets sealed with plugs to prevent impurities, ensuring transportation safety.

Marking Specifications

Outer Carton Marking: OE number, product name, adaptable engine model, quantity, batch number, weights and moisture-proof/shockproof warnings.

Product Marking: Laser-coded flange end (OE number, model, batch number, production date), wear-resistant and coolant-corrosion-proof.

Customization Service: Neutral packaging or brand LOGO-customized packaging available, with adjustable carton printing for foreign trade and domestic sales.

Inventory Status: Sufficient stock for regular specs, covering all WD615 series models.

Minimum Order Quantity (MOQ): 5 units.

Delivery Cycle: In-stock orders are shipped within 24-48 hours after payment, and bulk customized orders are shipped within 7-10 days.

Supply Stability: Monthly output ≥10,000 units; own production lines, molds and supply chains ensure year-round capacity, no delivery delays.

Certification Qualifications: IATF16949 & ISO9001 certified; third-party test reports (sealing, flow, service life) available on request.

Quality Guarantee: 18-month warranty; 7-day free return/exchange for non-human/installation faults; free replacement during warranty.

Q1: Fits all WD615 sub-models?

A1: Fits mainstream models (WD615.67/68/71); engine number required for special modified models.

Q2: Post-installation precautions?

A2: Clean flange, replace gasket + apply sealant; adjust pulley tension properly; bleed air after coolant refill; check for leakage/noise post-startup.

Q3: Sample supply & fee?

A3: Samples available (same as bulk quality); sample fee fully deductible from bulk orders, delivery in 1-2 days.

Q4: Warranty leakage handling?

A4: Provide fault photos/batch number; supplier reissues new product and bears round-trip freight for quality issues.

Installation Requirements

Check idle state (no noise/jamming) pre-installation. Clean flange (no oil/impurities), fit gasket flatly. Tighten bolts evenly (25-30N·m) to avoid deformation. Correct pulley coaxiality post-installation to prevent vibration.

Regular Inspection

Check for leakage/noise every 10,000 km. Inspect belt tension and impeller (via radiator filler neck) every 50,000 km. Replace coolant regularly to avoid corrosion from inferior products.

Storage Requirements

Store in dry, ventilated, light-proof warehouse; avoid oil/acid/alkali contact and extrusion. Unopened shelf life: 1 year; install promptly after opening, recheck idle state pre-installation.

Replacement Tips

Replace promptly if coolant drops fast, noise occurs, engine overheats or shaft leaks. Replace gasket, belt and tension pulley simultaneously to avoid secondary faults.
