Suspension rubber for CDM12.x

[JonHarrison]

Hi,

Does anyone know where I could get hold of a visco-elastic silicon rubber suspension bush for a Philips CDM12.x CD mechanism ? There are four that support the laser head assembly in the plastic suspension housing and I've just broken one whilst removing the old head unit . I think the Philips part number is 3149 194 00431.

Cheers,

Jon

Does it look like this?

Yes, pretty much exactly like that 😀

Are you desparate?
I have some at home but will not be back for 3 weeks!!

Ask Brent over on the CD63/67 mods thread. He will probably have some.

Hi Andy,

I'm not desperate just annoyed at breaking one 😱 . I've sent Brent a PM.

Cheers,

Jon

Yeah I have a set attached to a mech I can strip.

I found one of these last night on the floor under my desk?? Very random!

I'd be happy to post it if you send me your address.

I think Brent might be the best bet though because you'll be replacing all four at once. This means they'll be the same age and consistent bouncyness!

All the best,
Martin. 🙂

Source for CDM12.1 suspension

Hi,
Did anyone ever find a source for replacement mounts? These things are pretty fragile!

I've never noticed them to be fragile but there are different coloured versions so maybe some are worse than others?
As long as you're not looking for a many, there should be plenty lying around a repair shop somewhere.

Hi Martin,

Thanks for the tip. I used to own the only audio repair shop in the area. So to my knowledge there are none left in Vermont. I was hoping to be able to buy a dozen or so as I still occassionaly do some CD repairs w/ the Philips assembly.

How to remove CMD12.x without destroying the rubber mounts?

Hi,

Does anybody know the "correct" way to remove a CDM12.x without destroying the rubber suspension mounts?

On my player (Cyrus dAD3 S24) the slots for the rubber on the CDM open in the opposite direction to those on the player body, so seems impossible to remove the feet - other than by brute force.

Any ideas? Thanks!

Easy (if this is what you mean)... you use a small jewellers screwdriver and just push/prise the mounts away from the CDM12 body in a horizontal direction. You are pushing against the barbs in the CDM frame but the mounts slide out easily if you apply enough controlled force.

I have worked on many of these and never damaged or split one.

If you mean removing the "other end" then again, you use a small screwdriver and very carefully work one end of the bush into the slot it's pushed through. Then do the other side of the bush. They are very compressible and will go through the chassis slot. Be careful not to stab them or puncture them but they are pretty tough I find.

Thanks - tried to ease it out, with controlled force, but it just wouldn't go (also quite awkward to get a tool into the right position). Finally, knowing that I was replacing the CDM12.4 anyway, I didn't mind damaging the old non-working unit, so just snipped the plastic a little, and cracked the CDM's retaining tab off (gulp!), thus guaranteeing that the rubber mounts were in perfect condition, unstressed. And everything is fine.... now I just have to figure out where the white nylon drawer-switch cam mechanism goes - not obvious, after it fell out!
