Thanks, Grant. This is an esoteric process and difficult to describe clearly. By "cam tool," I was referring to the tool on the right, which fits into the ends of the cams without locking their rotation but prevents them from falling out. By "cam retainer," I meant the tool on the left, which also keeps the cams from falling out. The lighter-color links are seven links apart and were paired with the divots on the sprockets. So even if the cams rotated a bit during the process of fitting the chain over the pads, it would only matter if the chain jumped a tooth and a lighter link was no longer lined up with its divot. Also, it's my understanding that, once they're loosely held in place by these tools, the cams can be rotated by hand if necessary to line up the slot.
