[Kenwood] TS-940SAT fan help

Wed Nov 8 13:36:41 EST 2006

I had the noisy fan problem in my TS940SAT with both fans. It is not 
too hard to lube them, and if you use the right oil, there is no risk 
of causing a burnout. Try Labelle 101 oil. It is available from on 
line hobby stores and other places. You might find it in a local 
hobby shop that carries trains or other things with small motors. It 
has a long, thin applicator that lets you reach the fan shaft without 
complete disassembly of the radio. It is good stuff.
To lube the fans, just get a drop of oil on the shaft where it enters 
the motor. You do not have to completely remove the blades to do 
this, but you will have to loosen the blade assembly to uncover the 
shaft. When you put the blade assembly back on, don't mount it flush 
against the motor or you will experience a new kind of noise. Leave 
enough room so that no part of the blades will hit anything as they 
rotate. Pay attention to the small copper contact that rides against 
the shaft.
