Frozen band switch on Mohican receiver

[Bob Groh WA2CKY]

Mike,

Assuming we are talking about a switch is frozen where the shaft passes through the front bushing: I had a switch on an S-40B that was similarly frozen. I removed the knob (a major task in itself!), set the radio on it's back and just kept the area between the shaft and bushing wet with penetrating oil (actually a very light oil I use on HO train engines). Checked it couple times a day for several days, kept the oil on it and tweaked back and forth with a vice grip on the shaft and finally it broke loose.

Now in reading your email, I almost get the feeling you are saying that the switch is frozen at the wafer's? I don't have a good idea of what the arrangement is like inside. So I'll wait for the 2nd installment!

Subject: [HEATH-TEMPE] Frozen band switch on Mohican receiver

Well gang, the subject line says it all

got escrewed with this "works just fine" mohican

band switch is frozen

I can get it to move with a vise grip, but afraid I'll break out the  
wafer switches as the whole switch flexes when I attempt to turn it  
with the vise grip.

I've put some teflon micro oil on the shaft where it goes into the  
bearing and tried rocking the shaft back and forth.

right now.. unless I can free up the band shaft, this thing is a goner..

I did manage to get the band switch on the broadcast band and the  
receiver does work after a fashion

any ideas to free up a frozen shaft like this??
