I have an exact replacement tire on the way from a reliable source for a R2R pinch roller. I want to try replacing the tire myself as opposed to sending the pinch roller out to be rebuilt.

I think...
(1) cut the old tire off
(2) freeze the roller
(3) warm the new tire (no direct heat or high temps)

I should be able to 'slide' it on, right? Any other methods, tips or tricks here?

Thanks

I've never replaced a tire on a pinch roller but your plan sounds like a reasonable one. Let us know how it works out if you go that route or another one.

The only pitfall that I imagine is what if the metal "wheel" has grooves around it? Hopefully it is just a interference fit.

I always send this kind of thing to VM (Gary stork). There is also Terry's Rubber Rollers.

My concern would be getting the wheel to run true......for example, I can imagine having to "true it up" after mounting to the metal base.

The fact that you were able to buy the part gives some hope that your approach will work.

where did you buy the replacement? it seems odd they would make it separately and sell without clear instructions as to how to install

Bought from Just Audio Repair Center via Reverb.com. I did see a few different vendors selling just the tire, so maybe it's a friction fit as mentioned above and fairly simple. I'm willing to give it a try.

I would have thought that glue would be involved.....

In this one instance ( a pinch roller) you can probably get along without the glue if the fit is reasonably tight. The roller is passive, not driving any other mechanism. All that is needed is enough adhesion so that the bearing resistance (very small) can be overcome.

Well that was easier than I expected. Removing the old tire and cleaning up was the majority of the work. The new tire went on with a little wiggling and no heat/cold. Very good grip and no slipping. So this may not be a good example of a DIY refurb of a pinch roller as this one seems to be lacking any of the complications some of the other types out there might bring.

Good to know. I have an A-2300SD as one of my TEAC decks.

Great machines. Built like tanks and run forever. This one was a cosmetic mess - it had years of nicotine that took many hours to clean. But it was apparently part of someones system that smoked a lot yet listened to very few tapes as the heads are near perfect. It came with Teac NAB adapters that had to be gently un-stuck, and yellow (once gray) original Teac cables. This one I'm keeping.

Thanks for the input all!

The “A” series are much more robust than the “X” series. I have and have had many different models with the first being an A-4010. Still have several.

Thanks Rich, all,

Now on to find some 10.5" NAB reels and maybe some ATR brand tape.

I've had a few and my favorite was an A-3340S, but gave it away years ago to a family member. But don't really have a need for 4 channel these days, or really need the 15ips.

Make sure the Teac can bias and erase ATR tape, which is very hot (+9 I believe). Maybe check with a Teac forum to see if anyone has experience with it. ATR tape is costly and it would be a problem if it turns out you can't use it.
