This CAT Engine Parts cylinder block is a precision-machined engine Cylinder block built for the CAT C15 and CAT C18 diesel platforms. Machined from high-grade cast iron and stress-relieved before final boring and honing, it delivers the structural rigidity and alignment accuracy that a C15 or C18 engine needs after a major overhaul. As a dedicated supplier of CAT Engine Parts, we stock the Cylinder block 488-1675 and the remanufactured 10R-9370 alongside a complete range of C15 and C18 diesel engine components, so excavator owners, engine rebuilders, fleet workshops and spare part traders can source everything from one stable partner. Every Cylinder block we ship is dimensionally verified, pressure tested and inspected against the original CAT C15 and C18 specification before dispatch.
