:welcome: Hola! Yo no hablo mucho español, perdóneme!
Translated:
"It does not move the mini tractor. I dismantled the "clutch" or "friction disk" without removing the dish that will transmición chain. That dish has marked the hole where it enters one of the steel balls, as if tended to go further and leave a mark on the plastic. The opposite plate is not damaged. I do not find the point. If I adjust the nut much outside when I let the clutch get stuck and burn rubber friction. If nothing happens loosened. Someone has reformed?
From Argentina, thank you very much!"
