This wet cylinder liner is specially designed for Dongfeng Cummins 6BT/6CT engines, the core wear-resistant pressure-bearing component of engine cylinder block. It is integrally centrifugally cast with high-phosphorus alloy cast iron, inner wall with precision honing mesh oil storage texture, outer wall with multi-layer sealing ring grooves, compatible with used 5-ton wheel loader s and mining trucks equipped with Cummins power. As the bearing base for piston reciprocating movement, the honing texture on inner wall stores engine oil continuously to reduce friction loss of piston rings. Outer wall grooves install sealing rings to isolate coolant leakage, separate cylinder block from combustion high temperature and protect block base, avoid costly cylinder boring overhaul. Precisely machined per Cummins original drawing, outer diameter, length and sealing grooves fully match original cylinder block for press-fit replacement during used loader refurbishment. Bulk supply for domestic repair shops, used machinery refurbishment and overseas complete machine export, supported by Qinyang Hengsheng 7/24 multilingual cross-border remote after-sales service system.

This forged piston is specially designed for Dongfeng Cummins 6BT/6CT engines, the core power component of engine combustion. It is integrally forged with high-silicon aluminum alloy, equipped with concave combustion chamber on top, plasma wear-resistant coating on ring grooves, and built-in wear bush inside piston pin bore, compatible with matching cylinder liner and piston ring for complete assembly. The piston reciprocates inside cylinder liner, the concave combustion chamber cooperates with fuel injector to realize full fuel atomization and combustion. Three ring grooves precisely fit piston rings to seal combustion gas and scrape redundant oil on liner wall layer by layer. High-temperature resistant coating on piston top resists instant combustion heat, effectively avoid piston top ablation and ring groove wear. Outer dimension, pin hole center distance and ring groove spacing fully comply with Cummins OEM standard, no trimming required during used loader engine overhaul, can be replaced as complete overhaul kit with cylinder liner, piston ring and cylinder head gasket. Bulk supply for domestic repair shops, used loader refurbishment and overseas complete machine export, supported by Qinyang Hengsheng 7/24 multilingual cross-border remote after-sales service system.
