I have a Nakamichi Dragon on the bench. I need to dismantle the DD
motor. To do so, I have to remove the circlip thingy (see photo:
https://imgur.com/a/5pEwdVw ). It must be destroyed during removal,
which means I need a replacement, after repair. The bearing is 13mm in
diameter. Any ideas where one can be found. Oh, and what it is called
would be nice too.

TIA

** Seen similar ones holding plastic neon bezels on to front panels of Marshall valve amps.

FYI
The BLDC motors in Roland tape echo machines have a small ball bearing ( 13x5x5mm) on the output shaft that goes bad.
Side play develops and the motor runs slow or even stops.
The fix is to push another, identical bearing right of top of the bad one.
Cos extracting the old one is a PITA nightmare.

If no-one here knows, I could ask about it on PFM as a number of repair
bods post there.
