Yes it does have the 8.3 cummins. The motor shelled out at 4500hrs. The mechanic said the oil pump had failed. He claims that is what will get the cummins so since then we have just replaced the pump around 3000 hours to play it safe. Actually had it changed this past harvest and the mechanic said it was good that we did as it was starting to get weak........ Good or bad I am not sure but since the original motor going at 4500hrs we have since got over 6000 more hours on it and it runs like a beast.
