[QUOTE="RJCarp2, post: 16070961, member: 104030"] After more researching and reading the TFS instructions, I think I understand the issue. The crank keyway is stepped in the area of the aft gear. In other words, the groove in the crank does not go all the way back to the back face of the aft gear. There is a step in the keyway and the aft gear engages with more of the step than it does the solid key. The step is a wet noodle. It can't support the gear load. So the gear is only being fixed by a key half its length. This I think is why they fail. TFS instructions recommend machining the keyway farther back and installing a longer hardened keyway to eliminate the step. Since my crank was already at a machine shop for balancing, this is the route I'm going to take. [/QUOTE]
