Microscopic chance for radio part

[MBfreak]

Repairing a top of the Blaupunkt line 1968, a Koeln series X self seeking car radio, LW, MW,SW and FM.
Radio works perfectly, replaced all electrolytics in speaker driver part
Some specialist has sprayed the entire radio with loads of some kind of "cleaning spray "
that has also enered the small PM dc motor.
The commutator has five copper segments, OD appr 1/4 " l appr 5/16".
The spray has dissolved the glue holding the commutator segments to its pertinax spinner.
Photo enclosed.
Will pay good money for a working unit ( it runs on 2,7 V, appr 0,15 A )

Best regards

Ola

Thanks to all.
Tried all of the above and several more some weeks ago.

We had an ace radio guy on this forum some years ago.
RADIORON
He did incredible work. But not here anymore.
I have tried to contact him, no luck.

Any possibility of repairing the motor ?

Bill.
The entire commutator assy ( OD appr 1/4", l appr 5/16 ") had disintegrated due to some bonehead that had drowned the entire unit so that the 5 small commutator segments became loose, glue was dissolved.
Two of the very thin rotor wire assys had lost all insulation.
Way beyond my repair skills

@MBfreak -
I'm going to go over next door and ask my neighbor.
What numbers do I need to give him? All of the above (in the first post?)
You're just looking for that little motor widget?
Can't make any promises, but it might be worth a shot.
From what he's told me, his entire basement is filled with old car radios - he used to repair them as a hobby.
The rest of the basement is filled with the chrome trim off his 1953 Ford Crestline that's rusting away out back.

Thanks a lot.
The radio is a Blaupunkt Köln series X, which in Blaupunkt lingo means it is manufactured 1968.
This was the Blaupunkt top of the line radio, found in epensive MBs and even some BMWs.

And the part I am looking for is the little permanent magnet DC motor.
Including the plastic assy on the output dia 2,5 mm drive shaft, which has a number of "ears" that stops the motor spinning when a station is found and a gear that drives the tuning mechanism.
( Not at all like the DELCO radios)
There are two small soldering lugs on he other end.
Dia is around 22 mm and length over metal part around 70 mm. It operates on 2,7 V and pulls 0,17 A .
There was an earlier Köln which had a much bigger motor, dia appr 45 , l 90. This will not fit in a X series radio.

All help much appreciated
