20R-4693 MAIN PUMP 350-0666 Hydraulic Pump For CAT414E CAT416E CAT434E CAT422E
We provide genuine new original hydraulic main pump with cross-reference part numbers 20R-4693 and 350-0666, precisely manufactured to perfectly fit CAT414E, CAT416E, CAT434E and CAT422E construction machinery models. As the core power component of the entire hydraulic system, this high-performance main pump accurately provides stable hydraulic pressure and continuous oil flow for all working operations, including lifting, digging, traveling and steering functions. It directly governs the operational sensitivity, working smoothness, operating efficiency and overall running stability of CAT E-series equipment, making it an indispensable key spare part for routine maintenance and hydraulic system overhaul.
Produced in strict compliance with standard OEM manufacturing specifications and industrial precision processing requirements, the 20R-4693 and 350-0666 hydraulic pumps feature precise dimensional tolerance and flawless assembly matching. They can directly replace original aging, worn-out, leaking or pressure-unstable pump assemblies without extra modification or professional calibration, greatly simplifying repair procedures, shortening maintenance cycles and effectively reducing overall equipment operating costs. Adopting high-strength alloy shell structures and upgraded wear-resistant internal piston components, these main pumps maintain stable hydraulic output under long-term heavy-load and high-frequency working conditions.
This premium hydraulic main pump effectively resolves common hydraulic faults of CAT414E, CAT416E, CAT434E and CAT422E machinery, including slow operation response, insufficient working power, weak hydraulic pressure, oil leakage, abnormal pump noise and system jitter during operation. Equipped with high-quality reinforced sealing components and anti-corrosion internal structures, it delivers excellent vibration resistance, dustproof performance and high-pressure durability, fully adapting to complex and harsh construction site environments.
Every 20R-4693 and 350-0666 hydraulic main pump undergoes rigorous hydraulic pressure testing, airtightness inspection and performance aging tests before shipment to eliminate potential defects and ensure ultra-low failure rates. As reliable aftermarket construction parts with superior cost performance, our hydraulic pumps support sufficient in-stock supply and fast global delivery. We offer 24/7 professional overseas after-sales service to help global customers minimize equipment downtime and restore machinery to optimal working efficiency.
