Hope that someone can offer some guidance. I just bought a 1968 CA160 with just 3K actual miles. The only thing wrong pertains to 1st gear. When taking of in 1st gear with either light or moderate throttle it sort of randomly "jumps" in and out of gear. There is no gear grinding noise nor clunking sounds. I can take off in 2nd gear with anything from light to heavy throttle without this problem. Third and 4th gears also work fine. I have removed both side engine covers, and the clutch. The shifter properly indexes the transmission into each gear. The spring loaded roller detent on the end of the shift drum also seem in good working order although I don't have any reference as to the spring tension. But, it would seem to "lock" the trans into every gear.

Any help would be most appreciated as I am not looking forward to splitting the cases if I don't have to.

I'm pretty sure you'll have to open the transmission up and look between the gears for worn out parts. I can't really say what it could be without experiencing the problem. Too bad it wasn't a 160 so you could use some parts from my spare tranny.
