I have a tube of white lithium greese and agree and will use it on the plastic gears i have cleaned all of the brass with gun solvent and dried and then cleaned with rubbing alk. I then used a high quality gun oil on the brass. Thanks again to all of you of you for the gentle direction, It was a hard job and the worst being cleaning the old sticky black ooze the old belt had turned into on the HARD  TO REACH motor drive pully . I have taken one last picture of the correct position of the belt placment for future brave soles who want to attempt to change their own belts. I will post again when and if it plays the first CD.

I haven't ever opened a CD50, and it is different (being a Japanese transport) to all the other B&O CD's on which I've worked (with Philips transports), so I can't comment on "HOW TO" here.

But I'd like to offer a "WHAT" - being the lubrication.

I am not happy with lithium grease on plastics, being that it dries out, and at some point, one has to disassemble everything again for a cleaning.

For me, Silicon Spray is absolutely the only lubricant to use for plastic-to-plastic contact. It is super-slippery, super-thin, does not harden or dry out, and one of its inherent properties is that it is very kind to plastics, in fact inhibiting chemical breakdown.
