Default Philips CDM-9 service?

Hi first off a service question, is it advisable to give the swing bearing a drop of light oil top bottom or both?

And can anyone say is the CDM-9 the same as the CDM-9/44??? I can't find this info anywhere??

Cheers George

Not interested in the 9/pro, just the 9 and the 9/44.

Cheers George

The CDM9-44 and CDM9-65 are basially the same.
The difference is in the lead length and is only very slight.

The designation CDM9 is meaningless without the /44 or /65 or similar.


I would not recommend using any oil.

Thanks Poynton, that clears things up about 9 v 9/44 v 9/65

I would not recommend using any oil.
Do you have a reason for this have you dismantled/inspected one?
Are there materials bearing parts involved that could react to oil.
Is the bearing itself roller or brass sleeve/bush

I asked one of our resident Philips laser experts @tiefbassuebertr to comment but he hasn't yet.

Cheers George

As I know, the CDM9 exist only in two basically versions:
1) with brushless motor (pro-version) - go to images under
用PHILIPS无刷马达和金属托盘升级CDM9摇臂机芯_jjjjjj1_新浪博客
2) with normal motor

All the other differences was only small details (e. g. lenght of the foil connector etc.).

If one have a certainly cd player for service, check one of the various cross reference list and try to buy a second device in used condition with exact the same CDM9 version - for me the most helpful way.
