R4C rubber dial bushing

Floyd - K8AC All Messages By This Member #82249 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. ? 73, Floyd - K8AC
Jim Shorney All Messages By This Member #82250 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.

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 :-) 73, Steve Wedge, W1ES Time flies like an arrow.

Stan Gammons All Messages By This Member #82254 开云体育 Yes. I used some Gates 4219XL, bought from O'reilly's, 3/8" id and about 5/8" od, hose to make a bushing for my TR7 PTO.?? I haven't had to replace the bushing on my TR5 yet, so I don't know if it's the same as the TR5. 73 Stan KM4HQE On 1/26/25 15:57, Steve Wedge, W1ES/4 via groups.io wrote: toggle quoted message Show quoted text 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.
