High-quality cylinder head assembly for PC200-8 (S6D107 engine)
PC200-8 S6D107 cylinder head assembly is a pre-fitted complete unit for 6-cylinder turbocharged direct-injection diesel engines, made for medium excavator overhaul. It comes fully assembled with valves, springs and collets. It has five core features:
Symmetric 4-valve layout per cylinder. Separate intake and exhaust ports ensure sufficient gas flow. It maintains stable air charge under turbocharged conditions and delivers fast throttle response during frequent load changes typical for digging cycles.
Integrated pedestal for EGR connection. The cast-in mounting base on the side matches the EGR system perfectly. Even exhaust gas recirculation lowers peak combustion temperature and emission levels, and removes leakage risks from extra adapter pipes.
Parallel zoned cooling galleries. Multiple branch passages wrap around valve seats and injector bosses. Each cylinder gets balanced coolant flow, solving the common overheating issue on the middle cylinders of this long 6-cylinder head and reducing thermal fatigue cracks.
Pre-tested valve train assembly. All valve springs are sorted by load during assembly, and valve sink depth is controlled uniformly. Repair teams skip component selection work and cut installation time significantly.
Combined leakage test for full assembly. Beyond standard hydrostatic test for the casting, the finished assembly goes through multi-path leak inspection for ports, water and oil galleries. Valve sealing performance is verified at the same time to catch poor valve seating or insert leakage before shipment.
This pre-assembled head is a popular aftermarket spare part for PC200-8 excavators. It features good interchangeability and performs reliably in earthmoving and quarry sites. It can be mounted directly together with matched overhaul gaskets.
