G4003g Change Gears Noisy

Stens 770-123 "00" Grease!

I've tried just about everything and this stuff makes my change gears super quiet. The only negative is changing the gears (sticky mess). The color is a semi-clear light blue gray. Much cleaner than the open gear lub.

Amazon has it for 22 a quart. I'm guessing one quart will last me 10+ years

Might give this a try. I've been using open gear lube and it gets all over the place.

If it's the same open gear lube I tried thats nasty stuff. I've got a 1942 Logan 200 that I restored about a year ago. As I mentioned before I've tried all sorts of gear oil, white lithium chain lube etc... Then I read about open Gear Lube and by the name I figured it would be perfect. After one shot to the gears I realized it was the same nasty tar stuff I spent hours (more like days!) removing during the restoration. I'm guessing it puts a great protective film on the gear teeth for sure but no way will I use it.

This 00 grease sticks to the gears great and unless you overdo it doesn't sling. What tells me it is really doing a good job is how quiet the gears run.

have you checked the gear clearances?
for example SB instructions say to use a piece of paper between the gears to set the clearance.
My SB gears ways very noisy before I adjusted the gears clearances, now very quite before oiling

My gears are not very noisy really and the back lash is about right... Just saying that this lube made them very quiet. With that said... the majority of the noise coming from my gears is from an area that is not adjustable, that being, the reverse gears for the feed. A little wear in the bushings no doubt.

Over time the gears will wear in and quiet. When I run my lathe in reverse with the gear train engaged it's very loud, but forwards even at high speeds it's fairly quiet. That's because one side of the teeth have meshed together, but the other sides are fairly new.

My Logan has cast iron gears which are nearly perfect. The only gear that has any sign of wear is the one on the spindle and it isn't too bad. There is a bit of movement in the reverse gears I need to address. It's making the gears mesh a little deep. Long term my only concern is the spindle gear and removing it. I'm guessing its been attached to the spindle for 74 years (1942 model)
