SAA6D107E Engine Cylinder Head Assembly 6754-11-1101 for Excavator PW180-7E0 PW200-7E0 PW220-7E

6754-11-1101 Complete Cylinder Head for SAA6D107E Engine – Compatible with Excavator Models PW180-7E0, PW200-7E0, and PW220-7E

Part No.6754-11-1101 cylinder head fits SAA6D107E engines, widely used for overhaul of PC200-8 and PC220-8 medium excavators. It can be supplied as bare casting or pre-assembled valve head. It has five core features:

1. Separated four-port flow guide layout. Four independent ports per cylinder. Intake runners are tuned for ideal swirl ratio while exhaust runners reduce backpressure. It achieves high charging efficiency under turbocharging and quick throttle response for cyclic digging loads.
2. Reinforced injector boss with annular sealing groove. Thickened injector pedestal comes with locating ring groove for stable seal ring positioning. It prevents high-pressure fuel leakage under continuous vibration and avoids fuel mixing into coolant and oil emulsification.
3. Step-variable cross-section cooling jacket. The gallery cross-section changes gradually to distribute coolant flow according to heat load. It controls overheating of middle cylinders and reduces thermal deformation risks on this long six-cylinder head.
4. Ribbed locating land for rocker cover gasket. A raised sealing rib is machined on the top surface to stop gasket shifting. Concentrated clamping force prevents lube leakage and keeps dust out of the valve train to protect rockers and valves.
5. Traceable multi-stage quality control. Blanks go through stress relief treatment. Every finished unit passes magnetic particle crack detection, hydrostatic test and flatness inspection with test records kept. Consistent quality makes it suitable for bulk export orders.

This interchangeable aftermarket cylinder head works reliably with overhaul gaskets and valve kits. It maintains stable sealing and power performance under tough field conditions such as earthmoving and quarrying.
