Description

The 348-9904 Cylinder Block is a core load-bearing component custom-designed for CAT C27 and C32 high-performance engines. As the "backbone" of the engine, it integrates key structures such as cylinder bores, crankcases, and main bearing caps, providing a stable installation benchmark and operating space for moving components like pistons, crankshafts, and connecting rods. Adhering strictly to CAT's original technical standards, this cylinder block is made of customized high-strength alloy cast iron, formed through precision casting and multiple CNC machining processes. It ensures that all structural dimensions are fully compatible with the original parts and can be directly used as a replacement for the original cylinder block. Whether for maintenance or overhaul of C27/C32 engines used in mining machinery, heavy-duty trucks, marine power, or generator sets, the 348-9904 Cylinder Block provides reliable support for restoring the engine's strong power and stable performance.

Advantage

  • High Original Compatibility, Unobstructed Installation:Developed and produced in full accordance with the original drawings of CAT C27/C32 engines. The key dimensional errors of the cylinder block, such as cylinder bore roundness, main bearing cap bore coaxiality, and mounting hole position accuracy, are controlled within ±0.02mm. It achieves seamless fitting with components such as the cylinder head, oil pan, and timing system of the original engine, eliminating the need for secondary processing of installation parts and significantly shortening the maintenance cycle.
  • Excellent Material Strength, Impact and Wear Resistance:Made of high-strength alloy cast iron containing chromium and molybdenum. After quenching and tempering heat treatment, the material's tensile strength reaches over 650MPa, and the Brinell hardness is maintained between 220-260HB. Compared with ordinary cylinder blocks, its high-temperature creep resistance is improved by 30%. When the engine operates under high load, it can effectively resist the impact force caused by the reciprocating movement of the piston and the extrusion of high-pressure gas in the cylinder, reducing the risk of cylinder bore wear and deformation.
  • Optimized Heat Dissipation, Extended Service Life:The interior of the cylinder block is designed with multiple sets of optimized cooling water channels. The cross-section of the water channel adopts a streamlined structure, which reduces the cooling liquid flow resistance by 20%, and the heat dissipation area is increased by 15% compared with the original standard. It can quickly take away a large amount of heat generated during engine operation, keep the cylinder wall temperature uniform and stable, avoid failures such as cylinder block cracking and piston seizure caused by local overheating, and extend the overall service life of the engine.
  • Strict Quality Inspection, Stable and Reliable Performance:Each cylinder block undergoes multiple strict inspection procedures before leaving the factory, including ultrasonic flaw detection to check for internal defects such as sand holes and cracks, fluorescent penetrant inspection for surface quality, and water pressure test (test pressure up to 1.2MPa, no leakage for 5 minutes). Ensure the qualified rate of delivered products reaches 100%, suitable for long-term stable operation under various harsh working conditions.
