The radio on/off - volume **** is friction fit onto a D shaft.
The D shaft fits securely into the ****, however the shaft on potentiometer or rotary encoder(?) assembly exhibits about 5 degrees of mechanical side-to-side play.(without moving volume)
Not planning to replace the potentiometer, so have plotted a solution to eliminate the movement by adding a rotary shaft seal.
APM-Hexseal offers a line of switch sealing componenent. A nut is insert molded into a rubber boot, several of which work with rotary shaft potentiometers.
The plan is to substitute the radio control nut with the rotary shaft seal/nut assembly. The dual inner seals will exert friction on the shaft whereby shaft no longer exhibits play.
Radio on-off volume control **** There appears clearance for a rotary shaft seal behind light pipe. The shaft flat does not extend down to threaded bushing, so a rotary seal will work. The nut is removed and replaced by shaft seal with integral nut. Image depicting how a rotary shaft seal can exert pressure on the rotary shaft. This is a two part seal (nut and boot) and is not the better solution, but illustrates the concept. This image depicts the rotary shaft seal with nut insert molded into rotary seal.. It features Military grade silicon rubber with two internal sealing lips which will apply tension to shaft and mask notchiness in **** sweep.
Will also survey backlighting and light pipe for improvement.
However, before disassembling radio, does anyone knows shaft diameter...and shaft bushing thread size/pitch?
Administrator... the word k-n-o-b is displayed as **** in post.
The word is a descriptive technical name for a component part in a rotary potentiometer or rotary switch.
works fine. I’ve seen that in the past a couple times but it definitely isn’t in the filter and unfortunately no fix. Just try to edit and retype and often it passes
As requested previously a few times, please don’t leave me random notes in the forum, it’s happenstance when I see them. Post in site suggestions forum or use private message thanks
