Part overview
About this Cylinder Head Assembly for WD615 / HOWO 371
A complete cylinder head assembly for the Sinotruk WD615 series, the 9.7-litre six-cylinder diesel used in HOWO 371, HOWO 375 and Steyr King tractors. Every unit is supplied fully assembled with intake and exhaust valves, springs, guides and stem seals, so the workshop can fit it straight to a prepared block.
Castings come from a licensed foundry and are machined on CNC centres to the original drawing. The deck is checked for flatness within 0.05 mm, combustion chambers are cc-matched across all six cylinders, and each head is pressure-tested at 4 bar for ten minutes before packing.
Standard and +0.5 mm deck heights are available for blocks that have already been resurfaced. Tell us your engine number when you enquire and we will confirm the correct valve size and injector sleeve configuration.
