I've used JB Weld on crank keyway repairs and it seems to hold up fine. But I
recommend drilling and tapping the crank snout for a retaining bolt and big
washer to snug everything up nice & tight. Doesn't need to be a monster bolt,
5/16 UNF grade 8 should be enough. Radiator & grill must be removed to do
this.
