First of all, I misspoke when I said inside diameter when I meant to say inside circumference.
I broke two wires during disassembly - the Service Manual for the CCR-82 does not address the need to slide out the battery clips from the battery compartment in order to allow sufficient movement of the main circuit board. Nor does it mention that the black wire connected to the negative spring terminal of the battery compartment is glued (i.e., staked) along its length in three places to the plastic base. After the main circuit board and the volume control and its small circuit board were unfastened from the plastic base, I found residue of the sub belt on the plastic pulleys of its circuit. As yet, I've not removed this residue -- perhaps I'll apply a solvent that is safe to use on the plastic pulleys but is effective in dissolving the residue on them. I removed the belt for the tape position counter and then I tied a cord snuggly around its track and cut it in order to lay it out and measure its length (i.e., the track circumference). The track circumference measured 3.8125". The existing belt dimension is .7mm thick by .7mm wide with an inside circumference of 3.75", which is about 98% of the track circumference. This suggests that the belt for the tape position is somewhat stretched but does not yet need replacement. Nevertheless, I'll replace it because the required disassembly effort to get at it has been expended. I placed an order with Studio Sound Electronics for three belts: * SBO7.2 for the Main belt * SBO4.7 for the Sub belt * SBO3.7 for the Tape Position Counter belt Keeper of the Primordial Bit (mother of all bits), -= Ron Wiesen =- _____ From: M100 [mailto:m100-boun...@lists.bitchin100.com] On Behalf Of Paul Pennington Sent: Tuesday, May 19, 2015 19:48 To: Model 100 Discussion Subject: Re: [M100] Replacement Belts for the CCR-82 ComputerCassetteTapeRecorder Ron; I rebuilt two CCR-82's about three years ago. The belts are available from Studio Sound Electronics in Indiana. Their web site still appears to be active: www.studiosoundelectronics.com These are square belts instead of round, but they work fine. You need to order: SBM5.3 Belt $2.00 SBM8.0 Belt $2.00 They charged me a dollar for shipping. If the belts have turned to black goo it is very difficult to clean the pulleys. The manual has good instructions and an exploded view of the chassis. If your time is worth anything at all it's probably better to pick up an electronic voice recorder on eBay :-) Paul Pennington Augusta, Georgia On Tue, May 19, 2015 at 1:47 PM, Mike Stein <mhs.st...@gmail.com> wrote: He did say that it was stretched... ;-) ----- Original Message ----- From: "John Whitton" <jwhit...@bellsouth.net> To: "Model 100 Discussion" <m100@lists.bitchin100.com> Sent: Tuesday, May 19, 2015 1:20 PM Subject: Re: [M100] Replacement Belts for the CCR-82 ComputerCassetteTape Recorder A rare misspeak by Ron.

I think you measured your old belt at 8" circumference, not dia. Please let us know how it goes. Regards, Bob
