Key Features
- Genuine OEM Cooling Integrity — Built to Genie OEM specification for the Perkins 1104C-44 engine, delivering the same flow rate and sealing performance as the original pump.
- Direct-Fit Replacement — Matches the original mounting pattern, inlet and outlet ports, and drive interface, so the pump installs to the engine block without modification.
- Broad Equipment Compatibility — Fits a wide range of Genie S-series telescopic booms, Z-series articulating booms, and GTH telehandlers powered by the Perkins 1104C-44 engine.
- Sustained Engine Protection — A correctly functioning water pump maintains proper coolant circulation throughout the engine. A worn or failing pump risks overheating, which can cause unplanned shutdowns and engine damage.
- Operational Safety — Engine overheating on an aerial lift or telehandler is a serious operational hazard. Replacing a failing water pump promptly with the correct OEM part keeps the machine within safe operating parameters.
The water pump circulates coolant through the engine to regulate operating temperature, drawing coolant from the radiator and pushing it through the engine block and cylinder head before returning it to be cooled again. On Perkins 1104C-44 powered Genie machines, maintaining this circulation is essential to sustained performance — a pump that leaks, loses flow, or seizes will cause the engine to overheat rapidly. Replacing a worn pump with the correct OEM part, Genie 102643GT, restores full coolant flow and protects the engine from heat-related damage.
