Signal-stat no.381-motor adjustment??

[Cleatus Snow]

I am a new collector,I have a signal stat no.381. any tips on motor adjustments? Seem really loud/motor to gear. I can send pics if it would help.just don't want to ruin motor or gears.

Also, any input on gear lube. I was leaning towards silicone grease.

i found the metal gear 381s to be loud. maybe even a little louder than a Federal Signal Fireball FB-1 (metal gear driven model)

Pics would help. If it's the older brass gear model, disassembly, cleaning, and light (sewing machine or gun) oil are recommended. Just a drop here and there, not too much. Assembly should be adjusted so there is a little play between the brass and worm gear. One drop of oil at each motor bearing is also recommended. This is done with the motor mounting screws. This light will still be louder than the modern motors. Nature of the beast.

Nice old version light. Do just as I said.

That is a nice light. I have a Fireball that sounds like I"m making margaritas in the blender when it runs.

Nature of the beast. With this light you never need a pilot light on your switch to know if it's on or not.
