Question CDM1: help please: removal of spindle motor shaft

Re the CDM1 (mk1) mechanism.

Does the spindle motor shaft come out from the top, or the bottom? Must I remove the disk turntable (how???), or the motor rotor to get it to come apart?
Thanks

Hi Steerpike,

Turntable and shaft are inseparable. They come out from the top. See attached exploded view from the service manual.

It's in a ReVox B226.
The spindle is a little "stiff" or feels heavily damped. No audio problems yet, but the disc stops immediately the power is shut off - there is no inertial run-on. I imagine there should be some free-wheeling of the spindle and disc, although the motor does not yet seem to be struggling to overcome the load. What prompted me to investigate this is that the transport has become a little noisier than I remember it being.

I had the same with my CD304MK2 CDM1, sometimes the toc won't read. I removed the underside motor parts only. The spindle rests on a teflon plate, it was lightly oxidated(brown), cleaned it(beware of scratches on axle, did that with a fingernail), new clock oil on bushes/spindel and some grease on teflon plate and its allright now.
You have to align the bearing until it turns freely when reassembled with locking of screws.

Good luck

Lourens, you wouldn't happen to have a service manual for the CDM1.2 by any chance?

AFAIK there is no dedicated sm for Philips CDM1 mkII (the one you're looking for?). I found this exploded view of it in the Philips CDD882 manual.
For complete servicing information of the CDM1 mkII you need to have the Philips CD880 manual as well.... Both, and many others on one cd, obtainable from http://ultranalog.com/
