IDP 3196715 piston is the core power component of CAT C18 large displacement heavy-duty diesel engine. It converts fuel combustion pressure into mechanical driving force through reciprocating movement inside the cylinder liner.

Piston ablation, crack, bushing wear or ring groove deformation will lead to engine power drop, oil burning, abnormal knocking and cylinder pulling failure. It is generally replaced together with piston rings, cylinder liner, connecting rod bearing and crankshaft bearing during complete engine overhaul.
