Pro-2055 Volume & Squelch Knobs

[shirsch101]

On a Pro-2055 I need to remove the volume and squelch knobs to lubricate so they don’t stick. Which knob comes off first the center or outer ring

Thanks

How do you pull off the volume and squelch knobs? Is there a tool or pliers?

Thanks

Butter Knife and PRY
By the way you use contact cleaner and it is done on the back of the controls.

The knobs are on top of each other. I was told to spray some wd40 on the shaft

Pull the center off with your fingers and use the butter knife on the outer knob.
You were given bad information for cleaning and maintaining electronics.
So if you do not want to take my advice you can wait for others.

The knobs don’t turn separately both turn together. The inner and outer shaft are rubbing each other and get stuck together

I had a PRO197 do the same thing I had to remove the controls out of the scanner the center shaft was bent I had to strighten it then clean the controls that were gummed up with the correct cleaner then replace it back in the scanner.

Thanks for the advice I appreciate it

The difference between Contact Cleaner and WD40 is that WD40 is an Oil and will attract Lint Dust Ect and gum right back up.
Contact Cleaner sold at Lowes will clean and Evaporate leaving the controls to work longer and better.

I had two Pro2096 scanners that did that. Tried several things but the shafts like to turn together due to age and poor design. Over the years the shaft bends just enough to cause this problem. The control is no longer available. I saw where someone made a small rubber washer that went behind the squelch which increased the effort necessary to rotate the knob. I got tired of holding the squelch while I rotated the volume.

If the shaft is bent too much, you might consider just replacing the pot. There's all kinds of tricks you can do so the knobs don't stick together, but that's on a straight shaft / good pot.

I know the feeling of holding the squelch while raising the volume or vice Versa

Be very careful when trying to straighten the bent shaft. It will snap off quite easily.

Having issues pulling off the knobess. I hate to use a pliers.

I've used small pliers and a washcloth so I don't mark the knob. Perhaps ask for help from your dentist (as it's like pulling teeth).

As mentioned above I fixed another's radio with electronic cleaner from radio shack i got when they were closing stores. Sprayed around it and rotated it, did it again as well works good now.
Yanking out parts suseptible to damaging it beyond repair.

With or without the knobs on
