Mars M40852 Fan Blade Hub Puller

Product Description

The MARS M40852 is a fan blade hub puller designed for removing fan blade hubs from motor shafts without damaging surrounding components. HVAC technicians use this tool during condenser fan motor replacements and other service calls where a blade assembly must be separated from a seized or press-fit hub. It delivers controlled, even pulling force, reducing the risk of bending the blade or marring the shaft. This type of specialty puller is a standard addition to an HVAC service toolkit for any technician working on residential or light commercial air-cooled equipment.

The M40852 is suited for HVAC service applications where condenser or evaporator fan blades need to be removed from motor shafts. It is particularly useful when a hub is corroded, press-fit, or otherwise resistant to manual removal. The tool helps technicians complete fan blade swaps efficiently without resorting to improvised methods that risk component damage or injury.
