Tuning problem in SB-101

[Kenneth G. Gordon]

I am attempting to resurrect an SB-101 that has been 
stored for about 20 years. This rig will be used by a retired, 
handicapped policeman, so I want it to work correctly.

At the moment, the only really serious problem I am having 
with it is that it will not tune below 25 Khz above the bottom 
of each band.

The LMO is acting like an internal stop is incorrectly placed. 
The frequency is correct. It just won't tune below, for 
instance, 3575 Khz on 80 meters.

However, as I remember it there are a stack of "washers" 
(for want of a better word) on the shaft. Each washer has a 
short "lever" on an edge, with the end of the lever turned 
down, and after the operator has turned the shaft a certain 
number of turns, those turned-down ends all line up and act 
as a stop.

I am wondering if it is possible that two or more of those 
things has "stuck"?

I seem to remember that someone else here had a similar 
problem a couple of years ago, but can't find the discussion 
in the archives.

Anyone remember the problem and how to fix it?

I really don't want to dismantle the LMO, but at this point I 
don't think I have much choice.

Suggestions?
