Original bearing assembly lasted 30 years. Why buy a cheap knockoff when this costs about $50 more than a knockoff. This is an original manufacturer replacement. It item comes with B&G Oil and Gasket. Shut off the furnace, drain your system (open vent in radiator to drain faster), replace bearing assembly., refill, be sure to to vent system and close all vents. I recommend a ratcheting wrench to speed up the job. You need an Allen wrench to release to coupler from the motor to the bear. If you still have an original coupler, now is the time to replace it.Perfectfit perfectMy old bearing locked up and this was a good replacement.This shipment came with only one gasket, the view shows two gaskets. That second unit is necessary to complete installation.excellent merchandise. everything is sealed and together. ONE washer comes with it, NOT 2. quite reasonably priced.This unit did not come with an impeller.Good replacement for original
