Information:
Engine Runs Smoothly
Recommended Procedure
1. Engine Used in a Lug Condition ... "Lugging" (when the truck is used in a gear too high for engine rpm to go up as accelerator pedal is pushed farther down, or when the truck is used in a gear where engine rpm goes down with accelerator pedal at maximum travel) the engine causes a reduction in the intake of air with full fuel delivery to the cylinders. Because there is not enough air to burn all the fuel, the fuel that is not used comes out the exhaust as black smoke. To prevent lugging the engine, use a gear where engine can have "acceleration" (increase in speed) under load.2. Dirty Air Cleaner ... If the air cleaner has a restriction indicator, see if the red piston is in view. If there is no restriction indicator, restriction
