Idler tire - Pioneer CT-F650

[62vauxhall]

Has anyone replaced the rubber idler in a Pioneer CT-F650? If so, what did you use and where did you get it?

A couple of years ago I acquired the deck, had an ID number lathed off the face plate and installed a belt kit from Vintage Electronics. Included was an extremely concise set of installation instructions but no idler - just an acknowledgement they do not provide them and a remark that it too may need replacing.

In my case it did but after removing and measuring the original then spending considerable time searching online, I was unsuccessful in finding a match.

That being the case, I soaked the old one in Rubber Renue and that did the trick for a while. But after time, it reverted to it's non functional state.

I would not mind having some confidence in restoring this deck so would appreciate any and all suggestions on where to obtain a new idler of the correct size.

Are you talking about the rubber pinch roller?
Did you see this?

No, not the pinch roller. What I'm referring to is a round "tire" that fits on a plastic hub and is responsible for FF, REW & Auto Stop - like this:



I have recorded the dimensions somewhere and was hoping someone would know a supplier of such things with a variety of sizes.

The CTF-650 was my first deck. Man I made a lot of tapes on that machine. I guess EBay might be your best bet for a idler tire. I would say Marrs Communications but you may never get your order. If all else fails use the same size O ring. I have done this to a Tascam deck and it has been working for the last 5 years.

Mcmaster Carr may be a source.

Mcmaster Carr may be a source.

Thanks for the tip. They do list a square profile O ring that's close to the dimensions I measured. The dimension which might be problematic is OD. I found the original to be .75" and the one on the McMaster Carr site is .691" - a difference of .06" or 3/50".

I need to open the deck up again to look at the idler in situ - that size difference might make the McMaster Carr replacement too small.

I used the square profile rings from McMaster in my Pioneer CT-F7272. They worked great. The size difference is probably not a problem but also consider that your originals are metric. McMaster has metric sizes, keep scrolling down the list. If you can't find the exact size try the closest inch size.

I revisited their website using "metric O ring" as a search term which led me to Square-Profile Oil-Resistant Buna-N O-Rings.

Is this the category in which you found those for the CT-F7272?

Those are the ones.

Did you ever find new tires? I'm working on my CT-F650 right now and running into the same problem.

Have you guys tried the WJoe Radio website? They offer belt kits that include the capstan tires. They also include printed instructions with diagrams.
