T560 Overhead motor

[Rochester]

Does anyone have advice / instructions on the dis assembly of the overhead motor / worm drive for the T560? I'm having clutch issues and wondering whether to change the clutch bearing or just tighten the screw tighter. TIA.

What issues are you having?

I (stupidly) left the groove motor running unsupervised so it ran right to the end of its travel. Since then it seems to move less freely and I need to tighten the thumb screw more in order to stop it slipping. So I presume I have damaged the clutch bearing.

Hm, its quite common for that to happen, and it shouldn't damage the clutch. It's more likely to be an issue with the lead screw itself. When you wind it back, the screw has to lock back onto the nut, so perhaps its cross threaded, or there is some grit / swarf stuck in there. I would try running it to the end of its travel again and gently winding it back to lock it back on.

Hey, I have been experiencing this on and off over the last week with my nut sometimes coming loose on its own, gave it a clean and flipped and it has been behaving now ha!

When you say :

"I would try running it to the end of its travel again and gently winding it back to lock it back on"

When you are winding it back are you leaving the nut loose please?

Thanks

Well the nut will come loose of its own accord.

For clarity: I was suggesting this as a solution to the free up the movement of the leadscrew, not as a solution to a sloppy thumb screw issue...
