Product Overview
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.

Core Product Features
- Honed Inner Working Wall: Cross mesh oil storage texture, continuous lubrication for piston ring reciprocation
- Double Sealing Grooves: Install rubber O-rings to block coolant leakage into combustion chamber
- Thick Pressure-bearing Tube Body: Integral high-phosphorus cast iron, no deformation under combustion high pressure
- Upper & Lower Positioning Steps: Precise limit for press fitting, ensure coaxiality with cylinder block to prevent eccentric piston wear
Core Product Advantages
- Inner & outer diameter, length and sealing groove depth strictly match Dongfeng Cummins 6BT/6CT cylinder block. No cylinder boring or polishing needed during used loader overhaul, direct cold press assembly with precise coaxiality to avoid eccentric piston wear, shorten refurbishment working hours.
- Integral centrifugal cast high-phosphorus cast iron with dense metallographic structure, qualified inner wall hardness. Resist cylinder pulling and rapid wear under long heavy-load mining & pushing work of used loaders, service life extended by 50% compared with ordinary cast iron liners.
- Cross honing mesh on inner wall stores engine oil stably, complete oil film during piston ring movement to seal combustion gas and reduce oil burning into combustion chamber. Black smoke and oil consumption faults greatly reduced after used loader refurbishment, fuel consumption cut by 6%-9%.
- Two standard sealing grooves on outer wall realize double-layer sealing to block coolant leakage, solve common faults of old liner s on used loaders such as water seepage and blown cylinder gasket, avoid costly overhaul caused by overheating cylinder pulling.
