We will be adding MANY notes / info as we go
thru old 'work sheets', more turntables and as time allows
and repairs are completed...

MCS 6500 turntable motor
disassembly / re-lube.
MCS turntables were primarily built by Panasonic /
Technics and / or used much of the same parts / subassemblies. There are
many steps to restoring a 'vintage' 1950's thru 1980's turntable and
re-lubing the motor bearings is one. Unfortunately most manufacturers of
turntable (and cassette decks, 8-track decks, reel to reels, VCR's etc) were
not envisioning consumers trying to utilize their products 20, 30, or 40 or
more years later, so some parts such as motors were considered to be
'life-time' products that never need maintenance. "Life-time" however
commonly means the 'usable' life-time of the product or 'product design' and
would typically be 5-10 years. The motors on most 'belt drive' turntables
utilize bronze bearings / bushings with polished steel shafts, with nylon
shims and are lubricated at the factory prior to assembly. There is not
typically any 'lubrication' access provided either for a professional repair
person or the end user, nor any lubrication points on the motors if they
were able to be easily accessed (the exceptions would be on some Reel to
Reel decks that do have lubrication / oil access points). They are also not
really meant to be disassembled for any service. Some are even soldered /
sealed shut, or utilize one time use 'press tabs' to seal up the housing
(making disassembly either not practical or destructive to pursue).
In the case of this example, the MCS 6500 turntable,
the motor and bearings were still functioning, but didn't 'feel' great, and
frankly, as we warrant our units and hope they will provide MANY MORE YEARS
of service, we proactively re-lube the bearings on most if not all the
tables we restore. Unfortunately you cannot simply 'drip' some oil on the
motor shaft and hope for the best (you can't even see the rear shaft on most
turntable / cassette deck motors). Following is a 'photo essay' of one we
recently did. Again, this is not meant to be 'how to' instructions, nor
permission for you to not head the above "CAUTIONS".
