Camshafts – Camshafts are examined and straightened, and all main journals and lobes are checked. Those that pass are machined to ensure proper valve lift and timing; those that do not meet specs are replaced with new.
Connecting Rods – Connecting rods are thoroughly cleaned and checked for straightness; those that do not meet specifications are replaced with new. Both crank and piston pin bores are checked for size, and 100% new bearings and bushings are installed.
Crankcases – Machining is performed to ensure all bores meet exacting dimensional specifications. Cylinder bores are honed with the latest technology. This level of precision ensures that bores meet EPA tier emission requirements. Wet sleeve engine sleeves are replaced 100% with new.
Crankshafts – Crankshafts are dimensionally and structurally inspected, then ground and micro-polished to exacting tolerances.
Cylinder Heads – All cylinder heads are inspected for cracks; those that pass are milled to ensure flatness. Valve seats and guides are machined with precision equipment to ensure proper valve seating, recession, clearance and runout.
Cylinder Sleeves – Engine with wet sleeves are replaced 100% with new. In dry sleeve engines, cylinder bores are enlarged and honed. In the repair process, a liquid nitrogen cooling tank contracts cylinder repair sleeves before installation, so once set, they expand to a permanent, pressed fit.
Painting – Guards, plugs, and grease protectant are used to avoid painting active surfaces. This prevents system contamination, misalignment, or leak-causing gaps created from melting or flecked paint.
Wear Parts – All pistons, rings, gaskets, bearings, bushings, seals, filters, and thermostats are replaced with OEM parts in every CNH Industrial Reman engine.
