The motor isnt mine , it came to me half dismanteled with all the parts in a non well packed cardboard box .
By the transport the parts were rubbing against each other , cracking the magnetwheel and sensor board .
They tried to get out the spigot by drilling , not at the best way . I've done that job more often by drilling with a 5 mm drill at the side where the M5 screw is .
About 20 mm deep and than hammer the spigot out with a 5 mm pin punch , later I made M6 thread in it .
I managed to get out what was left of the spigot and made a new one .
The long M6 bolts holding the gearbox to the bottomplate were loose and worn , the thread in the bottomplate also .
Drilled the bottomholes deeper with new M6 thread and bolts at custom lenght .
Imagine they managed to separate the gearbox from the bottomplate , still with the cover and the triangle alu adapter together .
That triangle adapter had cracks at both ears , repaired it with a 5 mm steel plate , also used to strengthening the bottomplate .
Put all together with inox bolt and nuts and now its ready for sending back to Germany .
