CDI Squashed rubbers

Posted by: Sean P on 05 December 2001

Can ayone suggest a way of reviving the "rubbers on the Top hat puck for a CDI. Mine appear fairly nackered and no amount of flicking and squeezing will bring them back into shape. For the first time I am experiencing disc slip/ misstracking because of this. Is a new puck still available.

Thanks in advance

Have you rotated the rubbers? There's a few ways to do this...

New pucks are still available, ask your dealer.

You can insert a round pin in the rubber's hole, large enough to stretch it just a little, leave this for 2 or 3 days.
You can also clean the rubber with a "rubber renewer" BUT TAKE CARE this stuff is corrosive for plastic.

Mike the top hat rubber/s are glued in place.

To that end remove it and rotate then glue back in place.

Or buy a new one from naim, about 12 quid I think.

With the pucks that came with my cd3.5 and cdx, the rubbers loop around plastic pin, and compressed onto the magnet subassembly. Spinning the rubbers is easy using a piece of blutack.

There's another way involving a razor blade and taking the whole puck apart, but it's probably not recommended.

Thanks for the replys.
Rubbers are glued on so can't be rotated. Using cocktail sticks thro rubbers holes limited sucess 3 hour listening session and they are flat again looks like its a new tophat.

Sean,

I would strongly advise against playing your CDI in its present condition. The disk slippage will cause excessive wear of the Nextel ring on the transport hub and lead to the transport becoming unrepairable.

After you have acquired a replacement puck, try to avoid leaving CDs in the player between listening sessions. This will preserve the shape of the rubber ring and prolong the useable service life of the puck.

Seconded.

Order 2 new pucks. Don't use the CDI until you receive them. The nextel ring will be damaged. It will cost you a fortune to replace and you will lose your CDI for one month.

NEVER LEAVE A NON-PLAYING DISK IN A NAIM CD PLAYER.

Thanks for the warning. Although how I am going to survive without music is a problem. Its a pity you can't order online. How about it P.S. give me an address and I'll get a cheque in the post. Normally I order through my dealer however If I wait the same time on the pucks as I did with my Stageline I won't see the pucks untill well into the new year. While vinyl will give me some music it only constitutes 20 percent of my collection.

Hoping for a positive reply

Works like a dream.

I small 'rubber sized' lump opposite the squashed rubber ring. When it flattens, you can reshape it!!

Give it a try..

Also on problematic cds put a little selotape to give it a better grip.

Phone naim direct I am sure they will help you out, even if just to tell you to call your dealer big grin
