Anyone have cassette player motors?

My old panasonic boombox from the late 70s just pooped out.

Opened it up and it looks like the cassette drive motor is seized. That's kind of weird. I turned it by hand and it does feel pretty sick! Lots of friction inside. I messed around with it for a bit then for some reason it got back to normal and when I plugged it in it spun again just fine. I tried putting it back together again, although keeping in mind it would probably only be a temporary fix, but by the time that was done it was back to not working.

The part number is MHT-5ST6Y and it is a 6VDC motor.

If anyone here thinks they have any motors around for this type of thing and from around that time please let me know and I'll post further details! It doesn't have to be a precise numbers match as I'm sure something else can be made to work.

Meanwhile I'll see if maybe just maybe I can make this one work again by rebuilding it somehow, but with these touchy tiny screws I fear I'll have to break out the drill and the blow torch!

Thanks a lot,

did you try oiling it?

Hi Simp,

I'll go ahead and give that a shot but I don't know if it'll work, something really feels messed up!

Well I found the problem. The shaft got stuck to the rear bearing of the motor, the bearing was spinning along with the shaft. I rebuilt it and now it spins freely again. However now the problem is that it doesn't power up! The brushes do seem to be making contact and sometimes I can feel it buzz when I get it close to the armature but once it's closed up nothing. Arg how annoying!

I have it fixed. The problem was a hairline crack in a copper strip holding/forming part of one of the brushes. When I voltage checked it, the slight touch of the probe must have made the gap close and thus it showed me a voltage. Eventually the gap got big enough where even the voltage checker didn't give me a reading and that's when I discovered the crack. Thankfully it wasn't a bad winding.
