8N1188 cylinder head for CAT 920, 930, and 950 wheel loaders and 518 skidder
Part No. 8N1188 cylinder head matches 3304 series 4-cylinder diesel engines, serving as overhaul replacement for wheel loaders, bulldozers, generator sets and marine power units. It has five core features:
Optimized spiral port for 2-valve layout. Two valves per cylinder with specially formed spiral intake runners create steady intake swirl. It helps full fuel-air mixing and delivers solid low-speed torque, ideal for long continuous heavy-duty mining applications.
Reinforced thick combustion roof. The thickened casting structure raises explosion pressure resistance. It withstands repeated combustion impact and resists bulging and cracking, perfect for generator and marine engines running at full load nonstop.
Zoned directional cooling water jacket. Separate guided water galleries focus coolant flow around combustion chambers and exhaust seats for targeted heat dissipation. It prevents hotspots and thermal deformation, extending the service life of the whole head.
Integrated external oil return passage. The oil return channel is cast into the side wall with a short, smooth route. It speeds up oil drainage and avoids oil accumulation inside the valve chamber, reducing oil seal leakage and excessive lube consumption.
One-setup machining for all reference holes. Bolt holes, injector bores and pin holes are machined in a single clamping operation. It guarantees precise positional tolerance and coaxiality. Parts fit directly without reaming or grinding, shortening workshop assembly time.
This heavy-duty cylinder head is a popular aftermarket spare part for construction and marine engine repair. When assembled with matched valve sets and overhaul gaskets, it maintains stable sealing and low failure rate under sustained high-load working cycles.
