"O" ring destruction.

[Bob Hardie]

Disclaimer... Just a thought:
I feel that heating up the radio, inside of radio, then cooling down can 
cause the rubber to dry out over a period of time.  Again, in repairing 
all those radios, I have chosen to use dial cord and have seen other 
mentions on here as to where to buy it.  The time spent is worth while 
as they will last for the rest of the life of the radio... "pert near" 
anyway. (granted one has to have the dexterity to do this operation.  
Perseverance is the key... HI...plus see the tip below.)

Use a stiff wire, bending the end with a hook in it to help route the 
dial cord around the wheels.  Actually, I found at the local electronic 
type supply house,  soldering aids that has the hooks bent just right to 
help guide the cord on the wheels.  The ones that I found are blue 
plastic with black metal ends on them.  Some of the solder aids have 
wire brushes on them, some are just sharp points like an ice pick and 
some are bent.    A kit was less than $6 if I recall. 
Hope this helps someone in their delema to solve the problem.    Bob,
