I dont want sabotage our worm gear discussion but wanted to throw in a
question about gear lube for a worm gear box. I am going to change the gear
oil in my US tower
box. It is a Hub City worm gear. Thinking of using a Mobil 1 Synthetic gear
lube, a PAG type.
Dont ask me what the PAG means but Hub City recomends a PAG synthetic. Any one
used a
synthetic ?
