The Multiquip 8970620860 is a genuine OEM Connecting Rod Bolt DCA-45USJ 4JG1 designed for the DCA-45USJ ultra-silent generator. As an authentic Multiquip replacement component, it is manufactured to the exact specifications required by the 4JG1 engine powering this unit. This bolt is confirmed compatible with the DCA-45USJ and ensures the connecting rod assembly is secured to the correct torque specification. Sourced directly through authorized Multiquip distribution channels, DHS Equipment supplies this part to keep your generator in proper working order.
Key Features
- Genuine OEM Specification — Manufactured to the exact thread pitch, shank diameter, and tensile strength required by the 4JG1 engine — no substitution guesswork needed.
- Direct-Fit for DCA-45USJ — Engineered specifically for the connecting rod assembly on the DCA-45USJ ultra-silent generator, installing exactly as the original hardware did.
- Critical Engine Retention Hardware — Properly torqued connecting rod bolts maintain rod-to-crankshaft integrity; a worn or failed bolt risks catastrophic internal engine damage.
- 4JG1 Engine Compatibility — Matched to the Isuzu 4JG1 engine used in the DCA-45USJ, ensuring correct material grade and stretch characteristics for this application.
- Safety-Critical Fastener — Connecting rod bolts are among the highest-stress fasteners in any reciprocating engine; using the correct OEM part is essential for safe, continued generator operation.
A connecting rod bolt secures the connecting rod cap to the connecting rod body, clamping the assembly around the crankshaft journal and transferring the force of combustion into rotational power. These bolts operate under extreme cyclic tensile loads and must meet precise torque and stretch specifications — using an incorrect or fatigued bolt risks rod separation, which can destroy the engine block. When servicing or rebuilding the 4JG1 engine in your DCA-45USJ generator, replacing connecting rod bolts with genuine OEM hardware is standard practice to restore full structural integrity to the bottom end.
