Multiquip 8973695545 Cylinder Block Assembly DCA25USI 4LE2

The Multiquip 8973695545 Cylinder Block Assembly DCA25USI 4LE2 is a genuine OEM component designed for the DCA25USI ultra-silent diesel generator series. This is the complete cylinder block assembly sourced directly from Multiquip, ensuring an exact-match replacement for the Isuzu 4LE2 engine at the heart of the DCA25USI. As a genuine OEM part, it is manufactured to the same specifications as the original component installed at the factory. Verify your model and engine code against 8973695545 before ordering to confirm correct application.

Key Features

• Genuine OEM Casting Integrity — Produced to Isuzu 4LE2 engine specifications, with correct bore dimensions, coolant passage geometry, and deck surface tolerancing that aftermarket castings may not replicate.
• Direct Application for DCA25USI — Engineered specifically for the DCA25USI ultra-silent diesel generator; mounts, ports, and threaded interfaces align with the existing engine architecture without rework.
• Full Structural Foundation — The cylinder block is the primary load-bearing structure of the engine; using a correctly specified OEM assembly preserves the alignment of all internal rotating components.
• Isuzu 4LE2 Engine Compatibility — Matched to the 4LE2 powerplant used in the DCA25USI platform, ensuring correct cylinder count, displacement configuration, and accessory mounting positions.
• Critical Sealing Surfaces Maintained — OEM casting quality preserves the head gasket deck, liner bore, and main bearing saddle finishes necessary to achieve proper compression and oil control on reassembly.

The cylinder block is the structural core of a diesel engine — it houses the pistons, cylinder liners, crankshaft, and coolant passages that keep the engine running under continuous load. Every major engine system, from the lubrication circuit to the top-end valve train, depends on the block's bore alignment and sealing surfaces remaining within specification. When a cylinder block is cracked, scored, or otherwise damaged, compression loss, oil contamination, and coolant leaks follow quickly, rendering the generator unable to produce reliable power output. Replacing it with the correct OEM assembly — part 8973695545 — restores the structural baseline the entire engine is built around, making it the critical starting point for any major engine rebuild on the DCA25USI.
