[TowerTalk] US Tower gearbox

[Bob K6UJ]

John,

I don't know the capacity of your TX455 gearbox but it would not be over 
one quart.
My HDX589 gearbox takes exactly one quart.
As you probably already know it is important to flush the old gear lube 
out with
the synthetic lube you are going to use.  The original lube and the 
synthetic are
not compatible.  I would order two quarts.  That should work fine for 
flush and fill.
Here's a supplier that I have used.
