The Multiquip 8941140540 is a genuine OEM Connecting Rod Bushing DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator. As a direct OEM replacement sourced from Multiquip, part 8941140540 is manufactured to the exact tolerances required by the Isuzu 4LE2 engine at the heart of the DCA25USI unit. This is not a generic substitute — it is the same component specified for original assembly, ensuring a correct installation without guesswork. Contractors and rental fleets depending on the DCA25USI for continuous power output can order with confidence knowing this bushing is built to perform in that specific application.
Key Features
- Precision-Toleranced OEM Bore Fit — Manufactured to the exact dimensional specifications of the Isuzu 4LE2 engine, ensuring correct oil film clearance between the connecting rod and crankpin for proper load transfer.
- Direct Engine-Spec Replacement — Engineered to seat into the connecting rod bore of the 4LE2 engine the same way the original component does, requiring no machining or shimming during installation.
- Confirmed Fitment for DCA25USI — Verified for use with the Multiquip DCA25USI ultra-silent diesel generator series powered by the Isuzu 4LE2 engine.
- Protects Crankshaft and Rod Integrity — A correctly fitted bushing maintains the oil wedge that prevents metal-to-metal contact; a worn or failed bushing accelerates crankpin wear and can lead to rod knock or catastrophic engine failure.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip component under part number 8941140540, providing assurance that the material grade and geometry match the original engine build specification.
The connecting rod bushing is a small but critical engine component pressed into the small or big end of the connecting rod to provide a precision bearing surface between the rod and the crankpin or wrist pin. It absorbs the cyclical load forces generated during each combustion stroke and relies on a controlled oil clearance to maintain a lubricating film that prevents direct metal contact. When this bushing wears beyond its service limit, clearance increases, oil pressure drops at that journal, and the resulting rod knock can quickly escalate into serious internal engine damage — making timely replacement essential to keeping the DCA25USI generator running at full rated output.
