Multiquip 8972315444 Cylinder Block Assembly DCA25USI 4LE2

The Multiquip 8972315444 is a genuine OEM Cylinder Block Assembly DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator. As a direct OEM component, 8972315444 is manufactured to the exact tolerances required by the Isuzu 4LE2 engine powering the DCA25USI, ensuring correct bore geometry, coolant passage alignment, and mounting interface compatibility. This is a core structural engine component sourced directly through Multiquip's authorized parts supply chain and sold by DHS Equipment.

Key Features

• OEM-Grade Bore Tolerancing — Cast and machined to the precise cylinder bore dimensions of the Isuzu 4LE2 engine, maintaining correct compression ratios and piston clearances.
• Direct Engine-Mount Compatibility — Matches the exact bolt pattern, deck height, and coolant port layout of the DCA25USI generator's engine block for a straightforward swap-out installation.
• Confirmed Fitment for DCA25USI — Engineered specifically for the DCA25USI ultra-silent diesel generator equipped with the Isuzu 4LE2 engine platform.
• Structural Integrity Under Load — The cylinder block is the backbone of the engine assembly; a genuine OEM casting ensures correct wall thickness and material density to handle sustained generator operating loads.
• Fuel and Coolant Passage Accuracy — Internal oil galleries and coolant passages are cast to OEM specification, supporting proper lubrication and thermal management throughout the engine.
• Critical Safety-Relevant Component — An improperly fitted or substandard cylinder block can lead to catastrophic engine failure, coolant loss, or oil contamination — genuine OEM sourcing eliminates these risks.

The cylinder block assembly is the primary structural casting of the engine, housing the cylinders, pistons, and crankshaft bearing bores while routing oil and coolant throughout the powerplant. On the DCA25USI ultra-silent generator, the Isuzu 4LE2 engine relies on the cylinder block to maintain precise dimensional relationships between all internal moving components — any deviation in bore size, deck flatness, or gallery alignment directly affects compression, lubrication, and engine longevity. When a cylinder block is cracked, worn beyond service limits, or damaged by overheating or impact, the engine cannot be reliably rebuilt without replacing this foundational component.
