Normaly I have to repair my wife's car, but this is more important

First of all the number and type, if not Martin will ask for it🙂

Bottom cover of and inside the envelope, a very good sign, still glued to the cover

Inside the envelope, the drawing

The inside looks like new, this deck didn't see much use, on all adjusting screws I can see the lacquer placed from the factory, screws has never been touched (red arrows)

Drive out, everything dry and with small amounts of dry grease, but nearly all clean.

Drive with suspension out, motor open

The belt drive wheel, I will have to make a new one 20 % smaller maybe in poliamide

Other side

Nice project !  🤒

And now some useless info:
Because of very high demands, B&O made a conversion kit for this. Incredibly rare, I never saw one but it
was available at some point.
The kit had a new motor and platter (with strobo markings for the Beogram 1200).

Repaired the wife and her car yesterday, but today I got to the more important work.

Here the prototype, made in Nylonacero, Polyamide for mechanics, it a little oversize where needed, I will have to refine it anyway.

The shaft is the original, not yet fastened to the wheel, will epoxy it when done testing the fit and location

As you see it fits perfectly to the idler wheel.

here side view, the wheel is overall diameter 28,5 Mm. the original is 35.4 Mm, so a little oversize, its easier to machine down if too big, than make a new piece, all together a 1.5 hour work. in the weekend I will clean, lubricate and install everything to see if I get some rotation. Then try to manipulate the belt to work with the new wheel, going to be interesting.😁

Brilliant job, Søren 🤒

I opened up my 1202 once so far (this was a while ago) and remember finding my envelope with schematics as well 😁

Also - I have a special surprise upgrade for my 1202, coming soon to a BeoWorld thread near you.

Got a little farther, took the the whole drive apart in detail, everything very hard and full with old very hard grase, had to scrape some of it off with a screwdriver

All clean

Together again, the new wheel was epoxied to the shaft, waiting for it to dry, before putting load on it, the motor was aligned with, checking the space around the rotor with linings, perfect fit, and runs very light.

Tomorrow I will try belt and functions, and I hope, play a record. Maybe I will have to adjust the new wheel a little

Perhaps we should start a betting line on what that first record will be.

I give 4 to 1 odds its Blondie - Parrallel Lines
