I am new to this sub and looking for the experts’ inputs please.

My e110 JD riding mower wouldn’t start and after trying everything I opened up the engine and found the camshaft in pieces. Going to replace it.

My concern is the broken pieces seem to have taken out a small slice of the bottom of engine cylinder wall as in the pic. Is this serious damage or is it worth repairing the camshaft?

Thanks in advance!
