CDM9/65 motor

[screamager]

Hello,

This is my first post in this forum.
I purchased an Arcam Alpha 6 CD player on ebay a few months back which turned out to have aparently broken in transport (the seller interaction is a whole other issue).
Initialy it seemed to be the gear that moved the tray, as some plastic gear teeth fell out when opening the box. I found info on the problem with the gear for the CDM9 transports and got myself a new gear for the player, optimal grease and instructions from Arcam on how to take the player apart to replace the gear.
I replaced the gear and now the tray functions flawlesly. However I now find myself with another problem. The motor does not seem to spin the disc. I insert the disc, press play and the motor seems to try to spin (makes a fraction of a turn), the laserhead moves in to read the disc, and then it all stops and I get an "Err" message on the display.

I assume its a problem with the motor not spinning the disc, but maybe someone out there has encountered a similar problem and found it to be something else.

I tried it with diffirent discs, including MFSL "gold" discs, so its not a problem of faulty discs, in any case I would assume that the disc has to spin for the head to read the TOC.

On ebay I can only find CDM9/44 transports for sale, no CDM9 pro (/65), so if there is an alternative to hunting down a transport, that would be great.

Can anyone point me in the right direction (towards either finding a CDM9/65 or another possible cause to the problem)?

Thanks in advance.

Hello,

I have an Arcam Alpha 5 plus with the same transport (cdm9/65) and last few days I have experienced the same problem - insert disc, press play but when motor tries to spin cd it fails and gives the error message "Err" in display.

Any success in solving the above problem?

What I found out is that if I manually help the cd to start spinning the cd will read for me, so my idea is to replace the motor or maybe try to refurbish it somehow. I located the serial on the existing motor, RF-300C-11400, and it seems like I can order a replacement on e-bay. Anyone did something similar before and can offer some advice how to perform a dismantle of the transport?

Thanks, Andreas.

Are there any signs that the laser is trying to focus first ?

It sounds to me that the motor is a little stiff (if it can be started by hand)

Maybe a little careful application of a penetrating lubricant may do the trick

Thank you for the quick replies. I will check further about the laser.

I managed to dismantle the transport and take out the motor. I ordered a replacement motor anyway since it was very inexpensive, but while waiting for the new I will try to add some lubricant to the existing one.

Solution found!

Tried to lubricate the old motor but with no success so I decided to wait for my replacement motor that I ordered. I received the motor with post today from www.cdlens.com and I must say I'm impressed with the service they offered, quick replies on questions and fast delivery (Poland to Malta in just a few days time). They had two very similar motors, I needed the one with the spindle length of 6.2 mm, not the one with 10mm.

So I mounted the motor and voila! CD is working again. Thanks for thread above, I found the part about distance between lens and disc most useful.

Thanks for your assistance and for a great forum!
