The engine will be dyno tested checking horsepower, RPM and oil pressure. (Some of these components may not be included with particular engines or applications based on engine type.) Our engines do not include belts, hoses, sending units, air compressors, flywheel, fan blade, remote oil coolers, starter, alternator or any special drive units. This engine will generally include the block, heads, valve covers, oil pump and pan, timing cover, turbo, rear cover, fuel injection pump with injectors, intake manifold, water pump, exhaust manifolds, and oil cooler. New “Timed” Cylinder Head with camshaft, cam followers and timing gears, water pump, oil pump, oil cooler, front cover and rear cover. New cylinder head “untimed”, crank, block & all internals new. Crankshaft is checked for size, reground, if necessary, and micro-polished to OEM specifications.
Connecting rods have new bushings installed and both large and small end are remachined to OEM specifications.
Blocks, heads and crankshafts are 100% magnaflux tested to avoid cracked components. Core plugs are 100% stainless steel to avoid corrosion. All heads are pressure tested and upgraded to the latest style valve seal. All heads get new valves and are vacuum tested to ensure the quali-ty of the valve job. Matched OEM requirements for piston type depending upon HP and application. Fastener Type Torque Spec Main cap bolts 95-105 ft-lbs Connecting rod bolts 40-45 ft-lbs. 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.ġ00% of pistons, rings, bearings, bushings, gaskets and seals. Computer controls ensure that each engine dyno test is conducted under standard, repeatable settings.
In addition, NPD uses OEM or equivalent The 6.7-Liter Cummins Engines CP3 Series (Common Rail) injection systems like the ISB Engines before. 6.7-Liter ISB Cummins Engine range from 225HP in the Freightliner, Sterlings, Bus, Yard Tractors, to 350 HP in the Dodge Ram Cummins Engines.Īll of NPD’s Complete Drop-In Cummins ISB Engines are 100% dyno tested prior to shipment. including pistons, rings, bearings, valves and gaskets, making sure that this engine will stand the test of time. NPD utilizes torque plating methods on the ISB 6.7-Liter Cummins Engines for boring and honing to ensure block straightness, which reduces break-in time and crankcase pressure. The ISB 6.7-Liter Cummins Engines are used in many applications including Freightliner Vans, Uniform Vans, Step Vans, Dodge Ram Pickups, Sterling Pickup’s, and commercial delivery vehicles.Īll ISB 6.7-Liter Cummins Engines are built will all Brand New Original Equipment or Equivalent Components.
