And the TR7 bushing, just to mess things up, is 5/8¡±
I have found that whatever Drake used in the 7 (and possibly the TR5) was softer. The bushings I have removed from a couple of them were semi-liquid.?
They work on the same principle. You need to be able to hold the skirt and move the PTO. It¡¯s not as important with the 5/7, since you have the digital display but we preservers always want to have everything working as it should :-)

The original suggestion that I saw years ago cited heater hose, which is what I used. It works well also and I still have enough for several more radios.

> My R4C dial scales started slipping today and I checked out the rubber bushing because of other posts here.? Sure enough, the bushing was hard as a rock.? I was able to find a suitable rubber hose for making a new bushing at the local Autozone store.? The hose has these markings on it: "50087 5/16" (7.9MM) Fuel Injection Hose SAE J30R9? Made in China" .? Unfortunately, the smallest length you can buy is 1 foot at a cost of $8.? I cut the proper length for the bushing and it worked perfectly.? There's no longer any slippage in the dial.
