Broken CDM9 Transport

jonclancy · 21st April 2003, 04:19 PM

Hi All,

well, typical Bank Holiday blues!!

My Arcam Alpha 6 tray jammed. I took the top off, retrieved the disc and thought that was the problem solved. It certainly wasn't!! The tray would barely open and shut. I have removed the transport for investigation and found that half the teeth on the plastic orange turret (which is belt -driven from the motor, mounted on a silver metal plate and secured to the bottom of the transport) have been stripped.

Does anyone know of a good supplier of replacement CDM9 transport mechanisms? Or can I just get hold of this one single part (ie the plastic toothed turret)??

Of course, if there is a superior solution that is a bolt on, I'm all ears...!!!

Thanks in advance for any suggestions / pointers you may have.

All the best

Jon

Don't scrap it or I'll come over to get it ! That is a serious threat

I know the orange gear you speak of and in my memory this gear has been modified. Don't know the part number unfortunately.

They were used in Philips CD9xx series too. Maybe finding one with a dead laser will solve your problem ? Finding a new CDM 9 will be difficult and expensive. There are some german companies that sell them for 140 Euro

But I googled this one for you:

edit: oops, I made a thinking error: the gear is part of the tray not of the laser unit. Please contact Philips for the gear. CD931 and 951 have the same gear.

In my database I found a gear which description says:
Gear from CD-tray (open/close)
Part number Philips: 4822-522-33192
Cost: €4.56 without transport.
Could this be the one?

It's listed in the CD931 & CD951 database.

Hi Hugo, you're the fastest as always

I'm pretty sure that it is the right gear. They are known for failure and I think it had something to do with wrong grease that was applied.

It's not me, it's my database...

To jonclancy: it can be ordered. Try Philips. If things don't work out, mail me.

Jon, please check this site if it is the right gear:

This might help.......worked great for me:

Here is the best info. I have on replacing the gear.

Good luck with the procedure.

I bought the gear from Robinson Racing Products Tel 209 966 2465 or
www.robinsonracing.com
I found it on the web it is a 32 pitch 10 tooth gear their number RPB
0100 for $3.50. I cut off the remainder of the old gear teeth and
slightly cut down the gear end of the old pulley assembly so that
when I mounted the gear on it (tooth end up) ,I couldplace a clip ring
in the notch of the original metal shaft so that the plulley assembly
wouldn't slide of. You have to cut the pulley back slightly to give
just enouth clearance between the gear and the clip ring that it turns
easily. I got a clip ring from the local Ace Hardwaree for 11 cents.
The material of the old pulley gear assembly is so soft that you can
easily cut if back with a sharp knife. I then used epoxy to glue the
gear on the pulley assembly. Rememger the collar part of the gear must
be mounted down so that the highest gear is furthest from the pulley
wheel. Use slow setting epoxy to give a strong bond. The thing works
fine. John

Thanks Guys! Spot on as usual!

I was amazed to see the pic on Eddie's site - exactly the same problem!! I have attached Eddies Pic and my own for comparison.

I'll be onto Philips tomorrow.

Thanks again. I'm kind of looking forward to re-assembling the kit.

Hi Jon, be sure to clean the new gear and lubricate it with a non-agressive kind of grease like silicon grease. Don't forget the axle.

As I said the gear gets weak from the used grease if I remember correctly.
