PC220-7 Fan Hub Assembly supports secure cooling-fan mounting for B2B excavator parts repair, overhaul, and wholesale sourcing.
The PC220-7 Fan Hub Assembly YNF18164 is supplied as a combined cooling-fan mounting unit consisting of the 6732-61-3430 retainer and 6732-61-3410 hub, with 3913433 also provided as a reference number. The assembly is used in the compatible PC220-7 cooling-fan drive area, where the fan is supported and positioned for stable rotation.
Unlike a simple spacer, the hub assembly forms part of the mechanical support structure for the rotating fan system. Correct alignment, mounting dimensions, and bearing or shaft interface are therefore important during replacement.
For B2B buyers, the YNF18164 fan hub assembly should be confirmed by all reference numbers, machine model, mounting layout, shaft or bore dimensions, and existing-part photos. Accurate matching helps repair workshops and distributors reduce installation errors, repeat freight, and machine downtime.

YNF Machinery supplies PC220-7 fan hub assemblies and related excavator cooling-system parts for machinery dealers, repair workshops, wholesalers, and international importers.
The YNF18164 assembly combines the 6732-61-3430 retainer and 6732-61-3410 hub, helping professional buyers source the required fan-support components as one matched set.
For B2B purchasing, the complete reference numbers should be provided together with the PC220-7 model, required quantity, bore dimensions, mounting measurements, and clear photos of the removed assembly. This is especially important because similar fan hubs can differ in shaft interface, flange dimensions, bolt pattern, or installation depth.
Related fan blades, spacers, pulleys, belts, shrouds, water pumps, and radiator parts can also be included in the same inquiry to simplify cooling-system parts sourcing.
