The 6210-11-8820 gasket is specified for the Komatsu HD785-5 rigid dump truck, sealing the joint between the rocker arm housing cover (part 6210-11-8111) and the cylinder head on the SA12V140-1 diesel engine. It is documented under the same figure, A1110-A7A3A (catalogue page 030020), directly alongside the cover it seals.
One gasket is fitted per rocker arm housing cover, so the quantity of 12 corresponds directly to the SA12V140-1's 12 cylinders — the same count as the cover itself. The Komatsu HD785-5 is a large rigid dump (haul) truck built for mining and quarry operations, powered by the SA12V140-1 diesel engine — a 12-cylinder (V12), 140 x 165 mm bore/stroke, 30.48-litre unit producing approximately 753 kW (~1,007 hp), per public HD785-5 specifications. The truck itself has a net load capacity of around 91 tonnes. Gaskets are a routine wear item, generally replaced as a set whenever the rocker arm housing cover is removed, since re-using a compressed gasket risks an oil leak at the cover joint.
Cross-Reference Part Numbers: 6210-11-8820 — Komatsu's parts documentation carries no alternate prefix or aftermarket cross-reference for this part; this is the single canonical OEM designation.
