MCS-TECHNICS BELT-DRIVE TURNTABLE MOTOR REPAIR DISASSEMBLY LUBRICATION DIY

 

The motors on most 'belt drive' turntables such as the ‘Technics / MCS’ in this example, 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. 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). However…

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".
