Push button switches on 40-190 - Bob - 01-14-2009
Hello all
Do the 8 push button switches need any kind of lube? I have cleaned the switch contacts using a contact cleaner. They cleaned up very well. The push buttons work well they lock in and release okay. Also on the tuner there are some ball bearing, is it a good idea to put some kind of grease on these?
Thanks Bob

Hello Bob. For the ball-bearings on the tuner section (variable capacitor), you can just spray a small amt of WD-40 into the bearings and the other frame points where the cap rotates, then rotate the tuner assy manually until it rotates freely and easily. Do this while set is unplugged & not operating. Remove the excess WD-40 overspray with clean paper towel or Q-tips. You should be good to go.

I use a little Lubriplate for bearings and switch contacts. Leaves a thin film of lubricant on the switch/control that I think lasts longer than WD40. Product has been around for years.

Product has been around for years.I never thought of using Lubriplate in a radio. I believe I have a tube of it left from an engine rebuild. Great idea. Thanks for posting it.

Thank you all
Got the tuner all clean and freed up. The Lubriplate sound like a good idea. Where would I get this from?

Hello all
I was able to get some Lubriplate. I used it on the switch contacts and the tuner ball bearings. It make a big difference on the switches, they seam to work nice and easy and snap on/off real nice.
Thanks Again

BTW, when applying lube. I like to do it sparingly. I also use a q-tip to apply it. That way it isn't getting sprayed all over the chassis or dial.
