DAMAGED KICK SHAFT FOR THE C/CA/CB/CL72/77 ENGINES

[LOUD MOUSE]

This is what happens when the kick shaft in a C/CA/CL72/77 engine isn't indexed at 11:00 o'clock. If it's at 12:00 or later the internal stop bolt will hit the big end and cause the splines to twist and eventually the spline end will shear off. Pic one is where the stop bolt hits and pic 2 is how the splines look as they first twist. ................lm

Perfect timing LM. I am put chain side back on last evening. Indexed at 11. Great info.

LM, can you please explain how to "index" it at 11 o'clock? Do you just have the kick start lever pointing at 11 o'clock when sliding the crankcase onto the threads?

Guess I got a small job tomorrow. My shaft is at 12 o'clock. "Indexed" I suppose means in the returned, relaxed state. My manual shows the kick arm at 11. Never really gave it much thought.
Thanks Ed.

Is 11:00 right for CB 77, seems to far back for front kicking. In your subject title, LM, you include CB
