I've got a 1993 Sony cassette deck - K611S - and the capstan motor has
recently started making a loudish hum. I tried a little lithium grease
on the spindle, and the noise diappeared for a few minutes. The pitch
varies when the speed adjustment screw is twiddled.
The part (X33566461) appears out of stock everywhere, and the fault
does
crop up on forums. I'm reluctant to chuck too much money at it though.
Any ideas on the cause and remedy?
Thanks, Rob
**Replace the motor. Replacements cost less than $15.00. IF the motor
can be dismantled (ie: It will have two or three small screws in the
casing), then it can be stripped down and BOTH bearings can be
lubricated with light machine oil, AFTER the bearing faces have been
cleaned. Such motors usually employ a mechanical speed regulation
system. Modern motors (ie: Anything made after 1980ish) employ
electronic speed regulation systems and are almost impossible to
repair,
without a significant machine shop.
It's much easier to replace the motor. Here in Australia, they are easy
to obtain. I expect they will be available in most other places too.
I've not got round to it just yet, but I can't find a replacement listed
at less than $60US - and then I'm not sure it's in stock. Here's a pic

Not sure if it has screws beneath the case tape.
Could you point me to a supplier?
Thanks, Rob
**That's a bog-standard, electronically regulated Mabuchi motor. I can't
tell if it is CCW or CW (CCW is more common), but it is likely to be a
12 Volt type. It's swaged together, making repair all but impossible
(you can't get to the thrust bearing, without ripping the thing apart).
Either way, it's not worth it. My cost price is about 8 Bucks. Retail
(in Oz) would be about $12.00 ~ $15.00, depending. I have no idea where
you can buy them in Pommyland (or anywhere else). This is my supplier:
www.wes.net.au
Dunno if they'll post O/S, but it's worth a shot.
45 Bucks! (shakes head). PLUS 28 Bucks shipping! Jeez. What a rip-off.
Got a motor advertised as:
EG500AD2B MABUCHI SPINDLE MOTOR EG-500AD-2B 12V CCW
for £8 delivered.
Looks to be the right size/connector, but it's labelled 'Qingfeng'
EG500AD2B. There's no speed control screw as on the original - but I'd
let that go as it wasn't specified.
Is it worth querying this brand switch with the ebay supplier?
In the event it works perfectly. Thanks everyone.
