The 4B/3.9L Cummins is a popular engine used in step van applications including bread, snack, uniform, and other commercial delivery vehi-cles. This engine is also used in various industrial and construction applications. Diesel Experts utilizes torque plating methods for boring and honing to ensure block straightness, which reduces break-in time and crankcase pressure. In addition, Diesel Experts uses OEM or equivalent pistons, rings, bearings, valves and gaskets, making sure that this engine will stand the test of time.
Dynamometer Testing
All of the Complete Drop-In engines are 100% dyno tested prior to shipment. Computer controls ensure that each engine dyno test is conducted under standard, repeatable settings. Every engine is run through a warm
up cycle; three separate cruise segments simulating light, medium and heavy throttle conditions; maximum torque and horsepower tests; both high and low idle tests; and a black light leak detection test with dyed oil, coolant and fuel.
