Thank you for asking your question today . Most likely the answer is going to be no. The way to confirm this with 100% certainty, is to go into the parts catalog for both engines with the complete model information and any subsequent letters and numbers after those two models. Then you would compare part numbers for both. The part numbers do not match, it further confirms the answer to be no unless for some reason they do match . Click on this link below and also get the full engine tag model and serial number information so you can use that information to compare part numbers. I will also be glad to confirm this further for you once you post that information as well. It's a pleasure to help anyway I can.

I want to know is the main journals
The same size
Mechanic: Dan, Technician replied 2 years ago

Let me clarify my response on this. You have not provided the full engine model numbers for either model options that you are asking questions for. One of the engine models that you are asking about has over 1100 options that do not all utilize the same crankshaft. They are designed for different horsepower ratings as well as configuration for emissions. You need to be more specific on your engine that you are working on by providing the details off of your actual engine tags. It is never a good idea to build an engine using parts from another engine model that are not confirmed the same part numbers or you could be building Frankenstein or a grenade that is just going to result in failure. If you want to know if the crankshafts are the same, you need the full model information on both. Then a quick search with the link I provided I can do for you if you need me to once you provide me that information, but I feel pretty strongly that the answer is going to be no, they are not interchangeable. It is not just the journal size you have to worry about. It is also the nose design and flywheel side as well as the stroke of the crankshaft. I have been a diesel technician and have rebuilt engines for very long time. I can assure you, that any time a customer of mine has come up with ideas of mismatching parts, I walk away and leave them on their own. I would never put my hands in anything that has the potential to come apart. I'm trying to save you a lot of hassle and aggravation. This is not something you do in the industry. If you can provide me the information I asked for I will also further confirm whether or not the part numbers match with 100% certainty. It is more than just main journals that need to match.
