NC Cams: The items being lubed in the head of that tree is the variable plates, IE the bronze bushings between the driven and driving shaft and their sliding plates.The shaft and plates rotate at the same speed,the lube only works to make speed changes easier, and possibly reduce plate noise.
Actually , #2 is better, as it "sprays" less and reduces contaminating the variable speed drive (large belt) it is a set up much like the Bridgies.The shafts are drilled and ported with Zerks at the end.Just a touch every week or so will suffice.
The knee needs the thickest lube you can find ( maybe marine wheel bearing grease ) as the knee is heaver than a bridgie ( and a PITA to elevate without regular lube )
