As the title says, I broke my G0765 7x14 lathe yesterday. I was using a parting tool and it suddenly jammed and STOPPED the lathe. There was some loud clacking somewhere in the internals and I hit the emergency off. It was running at the "slow" speed gear selection on the back of the machine. The lathe WILL work when the gear selector is set to the high speed setting, but not the low speed. At the high speed setting it seems fine. So it looks as if I didn't break bearings or the gearbox frame. There appear to be stripped teeth inside the gearbox. when I turn the spindle by hand in the low speed gear, but not in the high speed gear
I searched the web but could not find a guide on how to strip down the gearing to access the gearbox. The exploded diagram is not detailed enough about what inserts into what, and what gears mesh with what other gears.
I think that the problem is with the combo gear (#24 in the "Main" parts diagram) but I can't tell what it meshes with. I assume that the combo gear and/or the gear it meshes with are damaged, so I should probably replace both. They are not terribly expensive from grizzly (hopefully they have them in stock!)
Does anybody have experience with this repair? Can you point me in a direction to a repair operations manual? What parts am I likely to need?
