CEC CD3100 CD player tray belt, puzzled indeed!


Hope somebody has a good educated guess at what the issue is here because it has baffled me so far.

I bought a CEC CD3100 belt drive cd player as non working item.

Got it and as I suspected it was the belt for the tray door, in this case it was so stretched it was just slipping on the drive capstan. A quick down and dirty fix was to cut it and tie it back together in a knot which actually worked surprisingly well and allowed me to play cds to prove it was worth going further.

Could not find anywhere the exact size of said belt so measuring the one I hadย  ( before I cut and knotted) and deducting approx. 15% for stretch ( figure most sites seemed to state was normal stretch), I ordered a rubber belt from eBay.

Now when this arrived it actually fit perfectly and the tray flies in and out tout suite and I thought my job was done.

Ha, if life was only that simple!

After putting the top cover back on and fitting back into the system cued up the first cd and... nothing!

It spins the cd, reads the tracks and total time but then will not play at all.

Replacing the new belt with the old knotted one and it reads and plays cds again just fine!

My best guess so far is that maybe the new belt is a little too thick ( it was the thinnest cross section one I could find but it is a fair bit thicker than the original).

Now how or why that stops it playing the actual cd I have no idea.

Which is where I hope somebody much smarter than me comes in..... please.. lol.

The C.E.C is performing well above expectations tbh.

Just last night I was listening to a Joe Cocker ultimate collection CD, Not one you would be noted to expect great sq from.

But it truly shone and held my attention deeply.

Very happy indeed.
A good tip for the future though George.
Or for anybody else with a similar problem.

Thank you
Thx Jetter.

Tbh I did not even think of emailing the manufacturer, not sure why!
But it is all good for now.

The new CEC are still a great deal even if you have to buy one direct from Japan and if I was in the market for a brand new spinner it would likely be at the top of my shopping list!
But for what I paid for mine considering the final fix cost zero cents I am very happy indeed!

I actually placed the Myrtle wooden blocks that came with the EX8 under the C.E.C instead as I already had Herbies footers and lampblack balls for the amp that made a tremendous difference on the old Ayre ax7e.

Now I just need a little more time to evaluate the difference

And I will also be placing "The Gate " into my electrical breaker box Saturday so exciting times indeed ahead!

I had been trying to follow the "wood for vibration control" thread but as per normal when a certain somebody gets involved it just turns into a peeing contest of which there is no return.

Shame as it started out promising.

Yes this CEC has really brought my CD to life again played through the EX8, it is a stunning combo.It is by far the best that CD has ever sounded to my ears with any configuration of equipment I have ever owned.
The kicker is that right now you can buy mint CD for $1 or less from most thrift shops, hard to go wrong!

They were some great links btw, I did not come across the marrs one.

A couple of other good places for belts are....

Kenselectronics.com

Dalbani Corporation on eBay.

Quite a selection between them.
Nonoise.
Yep been through all of those and a few more...lol.

I considered the goody bag of 50 or more belts as well.

But finally tonight I got her done!

A hairband.

Yup a 10c hair band from my daughter's stash has just the right amount of give to work.

Funny old world!

You are correct.

With the now two problem belts I think I may have it figured out.

The "problem belts I have are a little tighter than the original, a lot stiffer, less stretchy if you will.

This is I believe stopping the tray to go completely back into position.

So to fix it I really would need to know the exact specs of the original belt to order exactly the right size but even then the rubber composition could be totally different.

Lets hope my original knotted belt holds up for a while!
Not really.
As I do not know the exact size and specifications of the original belt that would be very difficult.

One thing for sure the original belt is a lot softer and more stretchy than anything I have tried so far.

However that also could be old age impacting its properties as well.

For now the down and dirty fix of original belt is still working!

Unfortunately in the big city, (lol), stores like Home Despot and Lowe's have put all the little mom and pop hardware stores out of business.

Our Ace hardware closed about 7 years ago and when I asked at our Home Despot if they had a selection of o-ringsย  you would have thought I was asking for cocaine by the look on his face!

So it is what it is.....

sometimes the simplest ideas can be the best!

Never even thought of an o-ring, that is a great idea.
Just boughtย  a pair of ebay and will see how they perform, certainly thinner at 0.8mm.
A whole $3.25 so no big deal if no improvement.

Thank you
Nothing I can see except change of belt.

So 2 things different with new belt.

1/ it is thicker cross section.
2/ it is tighter than old one.ย 

So I guess one question is, how tight is too tight?

Without knowing exact original belt specs its just educated guess work right now.
