Volvo Construction Equipment runs a hydraulically driven cooling fan on its loaders, excavators and articulated haulers, and describes the principle in its own literature: the hydraulically driven cooling fan regulates component temperature and can be automatically reversed to permit self-cleaning of the cooling units. That reversibility is why the fan motor and its drive pump are service items with their own failure pattern, and why ordering by model badge alone goes wrong so often.This section covers replacement hydraulic fan motors and fan drive pumps for Volvo EC excavators, A-series articulated haulers, L-series wheel loaders and G-series motor graders, including the 14533496, 14531612, 14641300 and 14673696 fan motors and the 14524187 to 14778109 fan pump family. Volvo part numbers are quoted as the bare eight digits, with the VOE prefix as a display convention only. Hauler main hydraulic pumps and pump drive housings are listed in the hydraulic pump categories instead, so a search for a fan part does not return the wrong circuit. Every unit is bench checked, photographed against your order and packed in a wooden case. Start with our 液压风扇马达诊断指南, and see the full hydraulic fan motor range for other brands.
