Glad i found this thread. I busted the stock crank in my 5.9 common rail and im replacing with 12valve crank and rods. Planning to installing soon and would have put in same way as cracked cap rods.
Should i really be worried about peen and polishing these rods? Might never be over 500hp in this truck.
I have never heard of any one "Busting" a 5.9 Cummins crank, especially in a stock setup. I would like to see a pic of it.... Unless you meant you spun a bearing.
