View Full Version : 1990 International 4700 dump truck

Hi, I just bought this dump truck. It has the 5 speed Allison auto trans, and the DTA360 diesel engine. At 50 mph the rpm gage goes to 3200 rpm. that is near the red zone. I don't know what rear end it has but I hear the 7.5-1 rear end does something like this.
Could someone give me some help on this high rpm? Is it normal or is there a problem? Is there a way I can get manuals on this unit?
Any help will be appreciated.
Thanks, jr_2
