Ball bearings in the motor, the spindle shaft and the gear stacks.
To replace the bearings in a Hayward Power Flo 1.5 HP pool pump, first, disconnect the pump from power and remove the pump housing by unscrewing the screws. Carefully extract the motor from the housing and use a bearing puller or a similar tool to remove the old bearings from the motor shaft. Install the new bearings by pressing them onto the shaft, ensuring they are seated properly. Finally, reassemble the pump by reversing the disassembly steps, making sure all connections are secure before reconnecting power.
Your question is very vague...is it how to remove bearings or how the replace bearings or how to size new bearings on an old worn shaft???? And what bearings??? There are several hundred bearings on a car...one kind of bearing on fishing reel...for or five bearings on a bicycle
The bearings are out of it. Replace Blower motor.
You will have to replace it. The bearings are worn out in the blower motor.
Take the motor in to a professionl pool service company or motor rewind shop.
Stop motor. Remove line spool. pull spool from shaft and remove cord or weeds from around shaft. Replace spool on shaft. Re start motor.
If the motor's shaft will not turn (is locked) because maybe its bearings have seized - up or the thing it is driving has got damaged so it won't allow the shaft to turn, the motor will overheat in short-order.
If the window motor runs, replace the plastic spacers with ball bearings or bolt nuts. Oliver said it.
on the blower most bearings are flange mount, and will have a Allen set screw locking the shaft to the bearing,
Lower steering shaft? could be due to salt and/or sand getting into universal type bearings, depending on climate vehicle is exposed too.
