Question from Hank in Cleveland: What's the Mack E-7 Engine insulation procedure for the cylinder sleeves and refitting the liner protrusion? Answer: Excellent question Hank. Three things to consider when looking at the insulation process for the Mack E-7 reman: ... read more »

Nearly everyone who operates, owns or manages heavy diesel transportation equipment knows the Federal Government instituted regulations in an attempt to reduce emissions, fuel consumption and bolster a positive impact on the environment, but how does remanufacturing of diesel engines and engine components fit into the equation? ... read more »

In the United States approximately 90% of all goods are shipped using diesel engines. This includes over the highway freight, marine and train transportation. Diesel tractor trailers alone consume approximately 20 billion gallons per year, and a fully loaded tractor trailer traditionally obtained approximately 5-7 miles per gallon. ... read more »

Capital Reman Exchange in Denver has recently acquired a massive inventory of camshafts, new parts, connecting rods, blocks and heads. Currently, Capital Reman has inventory of nearly 4,000 connecting rods, over 2,000 camshafts, many blocks, heads and new parts that include thermostats, gaskets, overhaul kits, pistons, injectors, turbos and much more. ... read more »

A major source of engine wear is the sideways force exerted on the piston through the connecting rod by the crankshaft, which typically wears the cylinder into an oval cross-section rather than circular, making it impossible for piston rings to correctly seal against the cylinder walls. Geometrically, it can be seen that longer connecting rods will reduce the amount of this sideways force, and therefore lead to longer engine life. However, for a given engine block, the sum of the length of the connecting rod plus the piston stroke is a fixed number, determined by the fixed distance between the crankshaft axis and the top of the cylinder block where the cylinder head fastens; thus, for a given cylinder block longer stroke, giving greater engine displacement and power, requires a shorter connecting rod (or a piston with smaller compression height), resulting in accelerated cylinder wear ... read more »

Manufacturing or rather Re-Manufacturing is alive and well in the heartland of America. Two companies are doing great things in the diesel engine remanufacturing industry: Capital Reman Exchange and CNH Industrial. Diesel engine remanufacturing in its truest form is the process of recovering used engine components and machining them to better than new form as per original engine manufacturer guidelines. Sometimes remanufactured parts surpass brand new components due to engineering upgrades, reduced prices and a more competitive warranty. Remanufacturing simply does not repair or rebuild a used component from a point of failure but rather build up a core part to "better than new" standards. All parts are then tested to make sure they meet or exceed OEM specifications so that the product is top notch for the customer upon delivery. ... read more »
