I have an Ingersoll-Rand SD100F pad foot roller with a Cummins B3.9-C in it that has recently started having an issue where the engine becomes wildly under powered when you attempt to move the machine and becomes even worse when you attempt to run the vibrator and the travel motors together. The engine starts easily and if your parked and at high idle it runs fine. One symptom that presents itself when the engine is under load is the exhaust smoke becomes a very heavy black like its not burning all the fuel. We have replace all the filters on the machine within the last 50HRS and checked the turbo and its spinning freely from what we can see on the intake side. I think that the gate valve on the turbo may be sticking because its hard to move by hand? My mechanic also thinks that we may have a hydraulic motor going out on the drum drive possibly or a main pump dying? Any help on trouble shooting this issue would be greatly appreciated.
