sounds like the countershaft bearing is crushed, dont start it no more, your spreading metal debris around. the balls in the bearing are fukt. you gonna have to tear it apart and hope the housing isnt screwed too, and your output shaft might be bent, ?????????????? its a big ass piece if steel but anything is possible

never use clipon masters unless they are properly safety wired and siliconed and even then you need to check it often.

my best guess without seeing or hearing it
