Would you believe DeWalt used to use nylon gears in the transmission of
their cordless drills? That made for a lot of repair bills. Now, they use
metal gears, and they last much much longer.

What can wipe out the plastic gearing besides oiling and lubricating them is
BANGING THE GEARS ON THEIR END STOPS! I'm talking about running the dial to
the end of their travel rotation quickly while tuning across the band. You
can do this all day long with metal geared radios but not those with plastic
gears.

I bought a new C-line when they first came out and the radios had plastic
gearing. (I had been using a metal geared TR-4 up until this point in time
and had been used to running and banging the dial up to it's end points
while scanning the band.). I found out very quickly you could not do this
with a radio with plastic gears. Within two months of purchase Drake had
sent me 3 new geared PTOs as replacements. (The banging warped the gearing
so they did not rotate smoothly and freely as when new). Once I changed my
ways and did not bang against the end stops, my problems with plastic gears
went away.
