I changed the waterpump on my truck and after I got everything back together I started it up and the engine started to shake so I shut it of. After inspecting the balancer I found that only the bolt came loose so I took it off to check it all over, I found part of the pin in the slot on the balancer. Tried to drill it out but dont want to mess up the crankshaft itself. So I ordered a Empire Crank Pin kit from XDP just i dont know if its worth it or if I should go with a factor crank pin? I am pressed for time so any good ideas is much appreciated?
