Hello Maybe someone has had contact and knows how to remove the rotor from Celma PRAa (claw grinder - handpiece). I have a problem removing the impeller to replace the bearings. The impeller is pressed into the sleeve and the stator behind it. Is there any way to take it out without damage? THIS...

So old age on the Besel Kaso 74/35 engine. The impeller is squeezed from the forehead.

I don't keep it secret, only the nameplate is in terrible condition. The engine is actually a BESEL The impeller is squeezed from the front I know, but on the impeller there is a plastic fan, followed by a black plastic spacer. When I try to remove the impeller, this insert bothers me.

I completely forgot that the rotor is catching. You need to heat this casing and then knock it on the edge of the table - the entire stator charge will start to slide out and after it the rotor.

Hello
Maybe someone has had contact and knows how to remove the rotor from Celma PRAa (claw grinder - handpiece). I have a problem removing the impeller to replace the bearings.
The impeller is pressed into the sleeve and the stator behind it. Is there any way to take it out without damage?

THIS is a newer model. Mine has an aluminum body
