Quoting myself:
>Bosch blower motors that are squealing, running slow or even seized
>can almost always be saved by freeing-up and oiling. This one can't
>because the switch was left on in high position while it was seized,
>until a terrible smell emerged and the fuse blew. Since the motor's
>dead, good chance to show how one is put together and where to oil
>it. Note that to get to the oiling places (except the outside of the
>rear bearing) you have to remove the motor, which is not very
>difficult if you have a vise. I'll have more pictures later showing
>how this is done. On the Meyle aftermarket blowers the design
>requires that a puller of some sort be built that will extract the
>blower wheel from its shaft; so generally speaking the Meyle is not
>practically serviceable.
