Hydraulic Gear Pump 17A-49-11100 for Komatsu D155A Bulldozer The 17A-49-11100 hydraulic gear pump is an essential fluid power component engineered specifically for high-load earthmoving and construction equipment. Responsible for driving the machine’s critical hydraulic circuits, this heavy-duty work pump ensures efficient blade control, stable pressure distribution, and responsive steering under demanding field conditions. Manufactured with robust housing materials and premium internal seals, this replacement gear pump provides long-lasting volumetric efficiency and minimizes power loss in heavy dozing operations. Product Specifications Built to meet or exceed rigorous industrial performance criteria, this pump is designed to withstand continuous high pressure and temperature fluctuations. Part Number: 17A-49-11100 Alternative Format: 17A4911100 Product Class: Heavy Machinery Hydraulic Components Pump Type: External Engaged Gear Pump / Pilot Work Pump Estimated Net Weight: 16.0 kg (Approx. 35.3 lbs) Equipment Application & Machine Serial Numbers This premium replacement gear pump is accurately matched to ensure precise fitment and system integration with the following crawler dozer series: Compatible Komatsu Bulldozer Models D155A-3 (Serial Numbers: 60001-UP) D155A-5 (Serial Numbers: 65001-UP) D155A-5 (Extreme Cold Terrain Configurations) Cross-Reference & System Compatibility Before completing an installation, verify that your current equipment setup aligns with these interchangeable references and system placements: Interchangeable Parts: 17A-49-11100, 17A4911100 Associated Engine Series: Komatsu SA6D140E / SAA6D140E engine-driven hydraulic assemblies Primary Function: Main hydraulic work circuit pressure generation or pilot pressure control system Installation and Hydraulic Maintenance Notes Technical Recommendation: To maximize the operational life of your new 17A-49-11100 gear pump, it is critical to flush the existing hydraulic system thoroughly prior to installation. Always change the hydraulic oil and replace all primary system filters. Foreign particulate contamination inside aged oil is the primary cause of accelerated gear wear, premature seal failure, and rapid pressure drop. Related Part Numbers NO P.N.
