ABSTRACT:
A bearing pusher for a squirrel cage blower, typically used in an air conditioning or hot air furnace installation, which enables the bearing to be removed quickly and easily with a minimum of effort and which comprises a pusher portion and a puller portion wherein the pusher portion comprises two complementary members which may be joined together to provide a centrally disposed hollow cylindrical portion adapted to surround a shaft and to provide slots to engage the puller portion and which extends beyond the slots along the axis of said shaft a distance which is slightly greater than the thickness of the bearing to be pushed so that the puller portion when engaged with the pusher portion may be so positioned as to readily remove said bearing from said shaft.
