The job is a piece of cake. It wasn't that easy to find the 14mm hex key though. I found a 14mm (long) key at a local industrial hardware supply shop for about 8 bucks.
I hoped that Craftsman made one since most of my stuff is Craftsman, but no such luck...
The lube really smells awful, so plan to get rid of it right away rather than having it sit in your drain pan stinking up your garage.
Experience is something you don't get until just after you need it.
