Please fill out the following to ask a question. MAKE: IH MODEL: 4700 YEAR: 2002 MILES: 365,000 ENGINE: DT466 I'm looking for a medium duty box truck preferably an IH with a DT466 or a Ford with a Cummins 6BT. I found an IH. The mileage wasn't listed. When I called, the salesman said it had 365,000. My next question was whether any engine work had been done? The reply was that the engine had been rebuilt. My next question asked whther it was an in frame which the salesman confirmed. The dealer did not do the engine work. The engine was rebuilt around the 255,000 mile mark. I thought that was a bit early. The dealer has been using the truck for parts delivery. Brakes have been worked as necessary. Other than checking oil pressure to detect issues, is there anything else I can do diagnostic wise to find issues. What kind of mileage can be expected out of an in frame rebuild? Any other suggestions to determine condition of the engine?
