Hello everyone!
A new member here... Been reading Peter's thread on the boom box reconstruction.
Meanwhile, I have a decent Theta Data Basic that needs a part. It works very well electronically (until I start modding it
); however has a bad drive gear for the drawer.
As owners of this drive know, Theta wants nothing to do with it.
Therefore, I am asking the community globally to check their parts drawers and see if they have a suitable (or exact) replacement for this pulley/gear piece. I am willing to pay for it- no hand-outs here! PayPal waiting...
I think the drive was/is called "Pro 9" or something like that... Should have payed better attention...
Dimensions:
Pulley OD= 43.00-43.15mm (probably made at 43)
Pulley Groove= ~40.25 as measured with my calipers. Note I cannot get ALL the way to the bottom...
Shaft major OD= 10.5mm
Shaft ID= 2.94mm (Probably made at 3mm)
Gear OD= 10.1mm (note most are broken in my case- which is why I need another!)
Gear root= 6.16mm (as best as I can measure)
Overall height= ABOUT 24mm. It is dished out on the bottom, and difficult to measure with calipers...
Color= orange-brown (and I don't care if different! just for identification purposes!)
It also has a small 'seal' on the bottom side (side against my hand) as well. The seal is light green if that helps at all... It rides on a brass shaft riveted to a steel plate in the drive.
Photo attached... Thanks in advance to everyone!!! (now off to read the electronic mods for this baby...)

Thanks for the reply!
I actually did find one there ($18 each shipped) but also read on other threads about an ABS replacement (better material) that I am interested in. The one on eBay appears to be a stock replacement (based on color and details) and will also fail the same death I'm sure...
Still waiting to hear from a member I e-mailed regarding the ABS replcement...

If you do get a replay form him, please let me know...I have four CDM9 to repair 8-(
I heard from no one (*cricket-cricket-cricket*)
So I ordered a pair from eBay... $18.00 each, including shipping.
I suppose it could be worse!
Of course it can...I've to buy four of them
Which one you ordered?
Looks like it's a common failure The very same happened to my Theta Data Basic. Get yourself a cheap as chips Philips (Magnavox in the US) CD player & cut off the geared part of the draw mechanism, the bit that has lost the teeth, then cut off the bu**ered bit on that pulley & plastic weld the new bit on.
Problem solved
E2A:- find yourself a remote control for something like a Marantz CD63 or similar & revel in all the new functions the remote control gives you
