The AJ61045 serves as the core component of the cooling system for medium-sized tractor engines, positioned as a cost-effective OEM replacement part. It features an integrated centrifugal pump assembly structure combining the pump housing, impeller, mechanical seal, bearings, shaft, and pulley tailored for specific engine models. Driven by the engine crankshaft belt/gear, it is compatible with ethylene glycol-water mixtures (adjustable from -37°C to 0°C) configured to OEM standards. It offers the core advantages of direct installation and zero-tuning. Its seal and bearing assembly undergoes durability optimization, with flow and pressure precisely matching requirements, effectively reducing the risk of equipment downtime during agricultural operations.

Perfectly aligned dimensions and pulley positions—no machining or modification required.
Ceramic-carbon mechanical seals withstand high temperatures and prevent coolant leakage.
Sealed ball bearings with pre-lubrication eliminate the need for additional grease.
Optimized impeller design ensures demands are met at both idle and rated speeds.
Cast iron housing and cast aluminum impeller suit harsh agricultural conditions.
Meets technical cooling standards for North America, Europe, and Asia markets.
Clean coolant lines. Inspect thermostat, radiator, and hoses for blockages. We recommend replacing coolant and thermostat simultaneously.
Tighten flange bolts to OEM torque specifications. Install gaskets correctly and ensure proper belt tension (10–15mm deflection).
Inspect every 500 hours. Replace coolant every 1000 hours to prevent scale buildup and corrosion.
