Hello monarch enthusiasts, I could use some guidance on how to approach the situation that I'm currently in with my new-to-me lathe.
I have a Monarch 14C that is in pretty good shape overall (could use a good cleaning though)but has a meshing issue between the Spindle Clutch and the Small Spindle Drive Gear. I am assuming the previous owner operated the lathe in reverse since all the clutch tangs in the headstock assembly slope away from the direction of rotation The contact surface may have fatigued then the two surfaces pushed away and damaged something in the linkage in addition to the gear and clutch tangs. Or they tried to engage the smaller gear while operating. Again, I'm making an assumption.
You can see in the attached photos how the tangs fully engage on the Large Spindle Drive Gear side but have more than 1/16 inch gap on the other side. You can also see that the Clutch Shifter Shaft Lever for the Spindle Clutch overshoots the Shifter Timing Pin. What you don't see is the excessive slop/movement between the Clutch Fork and its respective pivot shaft.
Is there a key or pin that could be sheared or damaged between the Clutch Fork and its respective shaft and won't let the clutch mesh further up the tangs of the spindle drive gear? Would the best approach be to completely disassemble the headstock?
Any observations and/or recommendations would be greatly appreciated.
Thank you in advance.
