CD960 belts specs & service manual

[ruting]

Hello friends of DuyAudio,

1. I own a CD960 with it's rewarded transport. The belts are worn/stretched and I try to get replacements. Does anyone have formal specs of the diameters and thickness of the square belts (4 in total) and recoomendations where to buy them in the Netherlands?

2. If anyone has a technical service manual on this machine I would be delighted to get a copy.

3. Last but not least, what's your experience with hooking up a separate DA convertor. Should I use optical of coax digital out? What is a fair priced DA convertor which realy sounds nice, you reccomend to me to look for?
I have a power amp with Balanced inputs so perhaps there is also a DA convertor (with attanuator) which I feed directly into the power amp.

You can get original replacement belts from SEME in the UK and Charles Hyde in the UK. Say you have a Marantz CD94, it's the same mechanism.

About £30 for the 4 belts. Tray belt, Cam belt, and two Motor belts (the small thin ones).

OR...

CPC do a range of near enough size belts, cost about £2 for all four.

AVBELT77 £0.26 37 x 1.9mm ( original=36.2x1.6) it will do for both Cam drive (the tray lifter) and Motor and belts.

AVBELT91 £0.55 51.5 x 2mm Tray drive belt (the very long one)

Are the belts the same for the CD12?

[IanAS]

I think so.

We've recently found that the supposedly OEM belts supplied by SEME and Charles Hyde vary in length.

Comparing the original and new belts we had 3 different lengths for each belt size. The CPC belts are different again.

None of the new belts were good enough on the last 960 repair. The new ones were too stretchy or seemed to have lost their grip. We reused some old original belts from various donor CDM1 Philips players and moved the motors so they were further from the pulleys. That tightened the belts a bit.

Just a bit more info in case it helps anyone:

Philips part numbers for the belts:

Tray 482235830903
Cam 482235830763
Motor 482235830762

Tray is the long one.
Cam is the short thick one.
Motor are the two short thin ones that go on the motor pulleys.

Same numbers for the Marantz CD94.

I think the OE tray belt might be 2.2mm diameter, so 10% thicker than the CPC AVBELT91. That might mean it stretches less and maybe works better.

This thread is about the Marantz CD94 which has the same belts, I suppose:

Marantz cd94: belts for loading tray

[IanAS]

Thanks for linking the threads.

Yes, they are the same belts in the CD94 and are interchangeable with the CD960 belts.


I just phoned Charles Hyde and bought their last two tray belts.

The motor and cam belts from them are discontinued.

From SEME the tray drive belt is discontinued.

Belt for the tray, part No from Philips 4822 358 30903 (482235830903) for me unknown.
Therefore I have study some service manuals for the Marantz CD-7 and CD-94
(Philips CD-304 MK-II and CD-960 uses the same Loader A'ssy)

Here a more exactly describtion of all needed belts for Philips CD-960,
Marantz CD-94, Philips CD-304 MK-II and partly Marantz CD-7
so as some Philips compact disc player from LHH series.

Follow belts are necessary for loader A'ssy A001, used both for old CDM-2/CDM-4
and new VAM12xx mechanism units,

You can repair sliping belts by shortening them. Cut-out 2-3 mm and glue together by cyanoacrylat glue. Route the cuts in skew direction, not perpendicular.

Repaired the 051M belt and it works again.

This is a good solution, if new devices are no longer available and if the rubber material isn't brittle (cracking through fissures). If I want to get special diameter sizes (individual belts), current meter of belt materials with certainly thickness is necessary. If I have this I can carried out the same methody. I have heard about such suppliers but I have forget the exactly delivery sources; perhaps you know this.
