Cyberlight tilt motor problem and other difficulties

Hello!
I am now a proud owner of 6 old cyberlights.
I changed the PFC capacitor and and all bigger power supply capacitor and there were no more faults.

The one that looks as new makes but is as old as the others makes the biggest problem.
There is a tilt motor named 02V at the end.
It works fine, but is heating very much, so that you cant touch it anymore, even when its not moving.
Is that the wrong motor? It looks like it has left the factory like this and was never used.
The other cyberlight right next to it has a 03V motor there instead.
Also,the lightpath is not clear.
It cuts off a small part of the projection from all wheels. Is this a fault of the reflector or the power lens in the middle?

Where can I get new 3773 drivers as a spare?
How much current does a blower draw?
Where can I get a new heatstop-glass?

I dont need to replace all of this, but I like to have the spare parts at hand.
