Grease recommendations for worm gear?

[John Garza (3665)]

Roland,

I had the same screeching issue with a 65. First thing to ensure is the wheel turns freely - a small flatblade screwdriver pushing the gear-teeth along should feel close to no resistance to the hand. Then ensure the worm gear and tip are lubed. If all that is done and it still screeches it's time to look at the connection between the worm gear and motor (aka clutch). I've had good luck with tubing and even RTV silicone pushed into the sleeve and then embed the worm gear within it. After it dries, it can still be pulled out by hand, but it provides good grip. -J
