That looks like it. I had to put a new cam in the k301 in my 123 for the same reason you need one now. It was a non-running basket case when I got it. It is almost 20 years now, but my memory of it is that everything has to come out of the crankcase to get to it. Might as well check & replace anything that is worn like worn piston/connecting rod/crankshaft etc while you are in there. When I did mine, it needed a new oversized piston, re-bored, bearings and a new (used) crankshaft.
I don't remember it being a difficult job, but it did require a generous application of dollars for parts and machining. On the plus side, it hasn't needed anything internal since then.
