TY175 clutch adjuster was created by PDXtyist

Lubed cable and attempted to readjust clutch lever. I'll try to ride and test this as soon as finish a few other things on the bike.
I am curious though about how to adjust the clutch lever. The OEM Manual and the Haynes book are really confusing. I am not too sure what the purpose is of the lever moving up and down as the adjuster screw is turned.
Thanks for any input.

The clutch actuator on that model has a screw with an offset pin that rides in the groove where I've drawn the arrow. Turning the screw raises and lowers the entire actuator.

The area where I've drawn the red oval is the area the pushes on the internal clutch pushrod... notice how it is "wedge shaped" getting thicker as you get closer to the end? As you raise the actuator with the eccentric screw you are bringing that wedge up and reducing the gap between the actuator and the pushrod. Lowering the actuator increases the gap. So by raising or lowering the actuator you can set the internal play between the actuator and the pushrod... too much play and the clutch will still drag with lever pulled... too little play and the clutch will slip.

Hope that makes sense!

Perfect description!!. The only thing i'll add [sorry MarkT] is you only have a half turn to play with but if you keep screwing in you'll bottom the adjuster out not necessarily up--or down but could be anywhere in between. So if it goes tight by going too far then back it off till you get the half turn up & down but everything still free to operate. By going tight i think the pin will be bottoming in the grove, or the threaded part is going through to touch. same end result of binding up. There, that makes me feel better lol.

Excellent discussion.
I think it'll make a lot more sense when I readjust later. The clutch seems to operate very well so I will leave it be.
For "instutional knowledge" maybe a step by step with photos would be beneficial. Thank you sirs. Good stuff!
